Chart Attributes

Functional Attributes

You can control a variety of functional elements on the chart. For example, you can opt to show/hide data labels, data values, y-axis values. You can also set chart limits and extended properties.

These attributes let you control the functional properties in a drag-node chart.

Name Type Range Description
viewMode Boolean 0/1 Whether to set the chart in view mode or edit mode. In view mode, end users will only be able to drag the nodes (which are marked as drag-able). In edit mode, they can add/delete nodes or add/delete connectors.
enableLinks Boolean 0/1 If there are any links defined on the nodes, you can opt to start the chart in link mode (rather than dragging mode) by setting this attribute as 1. Your users can, at runtime, toggle between link mode and drag mode using the right-click context menu of chart.
animation Boolean 0/1 This attribute lets you set the configuration whether the chart should appear in an animated fashion. If you do not want to animate any part of the chart, set this as 0.
palette Number 1-5 Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme.
paletteColors String List of hex color codes separated by comma While the `palette` attribute allows to select a palette theme that applies to chart background, canvas, font and tool-tips, it does not change the colors of data items (that is, column, line, pie etc.). Using `paletteColors` attribute, you can specify your custom list of hex colors for the data items. The list of colors have to be separated by comma, for example, `"paletteColors": "#FF0000, #0372AB, #FF5904..."`. The chart will cycle through the list of specified colors and then render the data plot accordingly. To use the same set of colors throughout all your charts in a web application, you can store the list of palette colors in your application globally and then provide the same in each chart JSON.
showLabels Boolean 0/1 It sets the configuration whether the x-axis labels will be displayed or not.
labelDisplay String 'AUTO', 'WRAP':, 'STAGGER', 'ROTATE', 'NONE' Using this attribute, you can customize the alignment of data labels (x-axis labels). There are 5 options: AUTO, WRAP, STAGGER, ROTATE or NONE. By default, this attribute is set to AUTO mode which means that the alignment of the data labels is determined automatically depending on the size of the chart. WRAP wraps the label text if it is too long to fit in one line. ROTATE rotates the labels vertically. STAGGER divides the labels into multiple lines.
useEllipsesWhenOverflow
Since 3.2
Boolean 0/1 When enabled in AUTO mode, long data labels are truncated by adding ellipses to prevent them from overflowing the chart background. The default value is 1.
rotateLabels Boolean 0/1 This attribute lets you set whether the data labels would show up as rotated labels on the chart.
slantLabels Boolean 0/1 If you have opted to show rotated labels on chart, this attribute lets you set the configuration whether the labels would show as slanted labels or fully vertical ones.
labelStep Number 1 or above By default, all the labels are displayed on the chart. However, if you have a set of streaming data (like name of months or days of week), you can opt to show every n-th label for better clarity. This attribute just lets you do so. It allows to display every n(th) x-axis label.
staggerLines Number 2 or above If you have opted for STAGGER mode as `labelDisplay`, using this attribute you can control how many lines to stagger the label to. By default, all labels are displayed in a single line.
showYAxisValues Boolean 0/1 The y-axis of the charts is divided into vertical sections using div (divisional) lines. Each div line assumes a value based on its position. Using this attribute you can set whether to show those div line (y-axis) values or not.
showLimits Boolean 0/1 Whether to show chart limit values.
showDivLineValues Boolean 0/1 Whether to show div line values.
yAxisMaxValue Number Numeric Value This attribute helps you explicitly set the upper limit of the chart. If you do not specify this value, it is automatically calculated by the chart based on the data provided by you.
yAxisMinValue Number Numeric Value This attribute helps you explicitly set the lower limit of the chart. If you do not specify this value, it is automatically calculated by the chart based on the data provided by you.
xAxisMinValue Number Numeric Value The node chart has both x and y axes as numeric. This attribute lets you explicitly set the x-axis lower limit. If you do not specify this value, the chart will automatically calculate the best value for you.
xAxisMaxValue Number Numeric Value The node chart has both x and y axes as numeric. This attribute lets you explicitly set the x-axis upper limit. If you do not specify this value, the chart will automatically calculate the best value for you.
use3DLighting Boolean 0/1 Whether to use 3D lighting effects while filling the nodes.
yAxisNameWidth Number (In Pixels) If you opt to not rotate y-axis name, you can choose a maximum width that will be applied to y-axis name.
clickURL String The entire chart can now act as a hotspot. Use this URL to define the hotspot link for the chart. The link can be specified in FusionCharts Link Format.
showPrintMenuItem Boolean 0/1 When you right click on the chart it shows a context menu. This attribute allows you to show or hide the "Print" option in the context menu.
unescapeLinks Boolean 0/1 Internally the chart decodes a Url that you set as link. Before invoking the link it again encodes the Url. If you are passing multilingual characters via a Url or do not want this decode-encode mechanism to be handled by chart you can set,`unescapeLinks='0'`.
yAxisValuesStep Number 1 or above By default, all div lines show their values. However, you can opt to display every x(th) div line value using this attribute.
adjustDiv Boolean 0/1 The chart automatically tries to adjust divisional lines and limit values based on the data provided. However, if you want to set your explicit lower and upper limit values and number of divisional lines, first set this attribute to false. That would disable automatic adjustment of divisional lines.
rotateYAxisName Boolean 0/1 If you do not wish to rotate y-axis name, set this as 0. It specifically comes to use when you have special characters (UTF8) in your y-axis name that do not show up in rotated mode.
setAdaptiveYMin Boolean 0/1 This attribute lets you set whether the y-axis lower limit would be 0 (in case of all positive values on chart) or should the y-axis lower limit adapt itself to a different figure based on values provided to the chart.

  • Decimal places to which the numbers will round to
  • Scaling of numbers based on a user defined scale
  • Custom number input formats

These attributes let you appropriately format the numbers displayed on the chart.

Name Type Range Description
formatNumber Boolean 0/1 This configuration determines whether the numbers displayed on the chart will be formatted using commas, for example, 40,000 if `"formatNumber":"1"` and 40000 if `"formatNumber":"0"`.
formatNumberScale Boolean 0/1 Configuration whether to add K (thousands) and M (millions) to a number after truncating and rounding it - for example, if `formatNumberScale` is set to 1, 1043 would become 1.04K (with decimals set to 2 places).

inDecimalSeparator String Character In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, the chart accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the decimal separator.
inThousandSeparator String Character In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, the chart accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the thousand separator.
decimals Number 0-10 Number of decimal places to which all numbers on the chart would be rounded to.
forceDecimals Boolean 0/1 Whether to add 0 padding at the end of decimal numbers. For example, if you set decimals as 2 and a number is 23.4. If `forceDecimals` is set to 1, the number will automatically be converted to 23.40 (note the extra 0 at the end).
yAxisValueDecimals Number 0-10 If you have opted to not adjust div lines, you can specify the div line values decimal precision using this attribute.

Chart Padding & Margins

PowerCharts XT allows you to manually customize the padding of various elements on the chart to allow advanced manipulation and control over chart visualization. Padding in PowerCharts XT is always defined in pixels, unless the attribute itself suggests some other scale (like plotSpacePercent).

You can also define the chart margins. Chart margins refer to the empty space left on the top, bottom, left, and right of the chart. That means, PowerCharts XT will not plot anything in that space.

It is not necessary for you to specify any padding/margin values. PowerCharts XT automatically assumes the best values for the same.

These attributes let you configure the functional and cosmetic properties of chart paddings and margins.

Name Type Range Description
legendPadding Number In Pixels Padding of legend from right or bottom side of canvas.
captionPadding Number In Pixels This attribute lets you control the space (in pixels) between the sub-caption and top of the chart canvas. If the sub-caption is not defined, it controls the space between caption and top of chart canvas. If neither caption, nor sub-caption is defined, this padding does not come into play.
xAxisNamePadding Number In Pixels Using this, you can set the distance between the top end of x-axis title and the bottom end of data labels (or canvas, if data labels are not to be shown).
yAxisNamePadding Number In Pixels Using this, you can set the distance between the right end of y-axis title and the start of y-axis values (or canvas, if the y-axis values are not to be shown).
yAxisValuesPadding Number In Pixels This attribute helps you set the horizontal space between the canvas left edge and the y-axis values or trend line values (on left or right side). This is particularly useful, when you want more space between your canvas and y-axis values.
labelPadding Number In Pixels This attribute sets the vertical space between the labels and canvas bottom edge. If you want more space between the canvas and the x-axis labels, you can use this attribute to control it.
chartLeftMargin Number In Pixels Amount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space.
chartRightMargin Number In Pixels Amount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space.
chartTopMargin Number In Pixels Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space.
chartBottomMargin Number In Pixels Amount of empty space that you want to put at the bottom of your chart. Nothing is rendered in this space.
canvasLeftMargin Number In Pixels This attribute lets you control the space between the start of chart canvas and the start (x) of chart. In case of 2D charts, the canvas is the visible rectangular box. Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, the chart automatically calculates this space depending on the elements to be placed on the chart. However, if you want to over-ride this value with a higher value, you can use this attribute to specify the same. Please note that you cannot specify a margin lower than what has been calculated by the chart. This attribute is particularly useful, when you have multiple charts placed in a page and want all their canvas start position to align with each other - so in such a case, you can set same margin value (a value large enough that it does not get rejected by chart owing to it being lower than the calculated value) for all such charts in the page.
canvasRightMargin Number In Pixels Like `canvasLeftMargin`, this attribute lets you set the space between end of canvas and end of chart.
canvasTopMargin Number In Pixels Like `canvasLeftMargin`, this attribute lets you set the space between top of canvas and top of chart.
canvasBottomMargin Number In Pixels Like `canvasLeftMargin`, this attribute lets you set the space between bottom of canvas and bottom of chart.

<categories> element

The <categories> element lets you bunch together x-axis labels of the chart. For a drag-able node chart, it's necessary to provide data labels using <category> elements under <categories> element.

These attributes of the <categories> element let you control the font properties of data labels.

verticalLineAlpha Number 0-100 Lets you set the alpha for category lines.
verticalLineDashed Boolean 0/1 Whether the category lines should appear as dashed.
verticalLineDashLen Number In Pixels If the category lines are to appear as dashed, this attribute defines the length of dash.
verticalLineDashGap Number In Pixels Sets the gap between two consecutive dashes.

<category> element

Each <category> element represents an x-axis data label.

In a drag-able node chart, it's necessary to provide an equal number of <category> elements and data items ( <set> element within each <dataset>). PowerCharts XT plots only those data items for which it could find a respective <category> element.

These attributes let you configure the <category> element.

Name Type Range Description

toolText String The tooltip defined in the `<category>` element appears only when the mouse cursor is hovered over the nodes. However, this will not appear when the cursor is moved over the data labels (except for a situation when long labels are automatically truncated with ellipses. In this situation, if the mouse cursor is hovered over a truncated label, the tooltip will appear with the full label). In case you want to set a short label and show the full label in tooltip, define the full label using this attribute within the `<category>` element. The tooltip with the full label will appear only when the mouse is hovered on the particular node.

<dataset> element

Each <dataset> element contains a series of data. You can provide data-set level cosmetics so that all data within that data-set will be plotted in the same color/alpha/etc.

These properties let you configure a <dataset> element.

<set> element

Each <set> element (child of <set> element) represents a set of data which is to be plotted on the graph and determines a set of data which will appear on the chart.

For a drag-able chart, a typical <set> element will look like:

<dataset seriesName='2006' id='S2006' >
    <set id='S1' value='35445' />
    <set id='S2' value='35675' />
    .... and so on ....
</dataset>

These attributes let you configure the <set> element.

All the values contribute to form a numeric scale on the x axis. You can modify this scale using `xAxisMaxValue` and `xAxisMinValue` attributes.
y Number Numeric Value The y-axis value for the node. The node will be placed vertically on the y-axis based on this value. The y value (numerical position on the y-axis) is not based on pixels. All the values contribute to form a numeric scale on the y-axis. You can modify this scale using `yAxisMaxValue` and `yAxisMinValue` attributes.
label String This attribute helps you set the name of this node, which would be displayed over the node.
color Color Hex Code For Multi-series and Combination charts, you can define the color of data-sets at dataset level. However, if you wish to highlight a particular data element, you can specify it's color at "set" level using this attribute.
link String You can define links for individual data items. That enables the end user to click on node and drill down to other pages. To define the link for data items, use the link attribute. You can define links that open in same window, new window, pop-up window or frames. Please see Advanced Charting > Drill Down Charts for more information. Also, you need to URL Encode all the special characters (like ? and &) present in the link.
toolText String Lets you define the tool text for the node.
alpha Number 0-100 You can define the alpha of data-sets at dataset level. However, if you wish to highlight a particular data element, you can specify it's alpha at "set" level using this attribute.

<connectors> element

The drag-node chart allows you to connect any two nodes on the chart using connectors. You can have any number of connectors on the chart, as long as two nodes are connected by one connector only.

These attributes let you define the cosmetics for all the connectors on the chart.

Name Type Range Description
stdThickness Number 0-5 Using this value, you can specify a number which will be multiplied by individual connectors strength to get the line thickness. Say, you have a connector whose thickness should be 2 pixels and another whose thickness should be 4. So, you can define this attribute as 2 and then specify the strength of first connector as 1 and second one as 2. This is useful when you're plotting network diagrams and you have to show link strength as connector thickness.
color Color Hex Code Color for all the connectors on the chart

Trend-lines

Using the <trendlines> element (and children <line> elements), you can define trend-lines on the chart.

Trend-lines are horizontal lines spanning the chart canvas which aid in interpretation of data with respect to some pre-determined value. For example, if you are plotting sales data of current year, you might want to add previous year's average monthly sales as trend indicator for ease of comparison.

Use the code snippet shown below to render a trend-line on the chart:

    "trendlines": [{
     "line": [{
                "startvalue": "177500",
                 "color": "#9b59b6",
                 "displayvalue": "Target"
             }]
                    }]

These attributes let you configure the trend-line cosmetic and functional properties.

Name Type Range Description
startValue Number Numeric Value The starting value for the trend line. Say, if you want to plot a slanted trend line from value 102 to 109, the `startValue` would be 102.
endValue Number Numeric Value The ending y-axis value for the trend line. Say, if you want to plot a slanted trend line from value 102 to 109, the `endValue` would be 109. If you do not specify a value for `endValue`, it would automatically assume the same value as `startValue`.
displayValue String Numeric Value If you want to display a string caption for the trend line by its side, you can use this attribute. Example:` displayValue='Last Month High'`. When you don't supply this attribute, it automatically takes the value of `startValue`.
color String Hex Code Color of the trend line and its associated text
isTrendZone Boolean 0/1 Whether the trend will be displayed as a line or a zone (fill-colored rectangle).
showOnTop Boolean 0/1 Whether the trend line or zone would be displayed over data plots or behind them.
thickness Number In Pixels If you have opted to show the trend as a line, this attribute lets you define the thickness of trend line.
alpha Number 0-100 Alpha of the trend line.
dashed Boolean 0/1 If you have opted to show the trend as a line, this attribute lets you define whether the trend line would appear as dashed.
dashLen Number In Pixels If you have opted to show trend line as dash, this attribute lets you control the length of each dash.
dashGap Number In Pixels If you have opted to show trend line as dash, this attribute lets you control the length of each dash gap.
valueOnRight Boolean 0/1 Whether to show the trend line value on left side or right side of chart. This is particularly useful when the trend line display values on the chart are colliding with divisional lines values on the chart.

Vertical Trend-lines

Vertical trend-lines help you create vertical trend-lines/zones.

These are vertical lines spanning the chart canvas which aid in interpretation of data with respect to some pre-determined value.

Use the code snippet shown below to render a vertical trend-line on the chart:

    "vtrendlines": [{
     "line": [{
                   "startvalue":"20",
                  "endvalue":"65",
                  "alpha":"5",
                  "color":"00FF00"
             }]
                    }]

These attributes let you configure vertical trend-lines in a chart.

Name Type Range Description
startValue Number Numeric Value The starting value for the trend line. Say, if you want to plot a slanted trend line from value 102 to 109, the `startValue` would be 102.
endValue Number Numeric Value The ending y-axis value for the trend line. Say, if you want to plot a slanted trend line from value 102 to 109, the `endValue` would be 109. If you do not specify a value for `endValue`, it would automatically assume the same value as `startValue`.
