Chart Attributes

Functional Attributes

These attributes let you 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.

Name Type Range Description
animation Boolean 0/1 This attribute gives you the option to control animation in your charts. If you do not want to animate any part of the chart, set this as 0.
palette Number 1-5 FusionCharts XT offers the concept of Color Palettes. 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 (i.e., 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 e.g., `"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.
clipBubbles Boolean 0/1 If bigger bubbles are placed on the edges of the chart, they might extend beyond the canvas. However, you can opt to clip those bubble edges so that they are contained within the canvas by setting this attribute to 1.
negativeColor Color Hex Code You can opt to color all bubbles with a negative Z value on the chart with a single color, which can be specified for this attribute.
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 3.2.1
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 will show up as rotated labels on the chart.
slantLabels Boolean 0/1 If you've opted to show rotated labels on chart, this attribute lets you set the configuration whether the labels will 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've 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. When a value greater than 1 (n) is set to this attribute, the first label from left and every label at the n-th position from left will be displayed. e.g., a chart showing data for 12 months and set with `"labelStep": "3"` will show labels for January, April, July, and October. The rest of the labels will be skipped.
xAxisLabelMode
Since 3.2.2
String AUTO CATEGORIES MIXED This attribute is used to render the x-axis labels in three different modes. The modes are as following: AUTO - Allows the x-axis labels to inherit the properties of y-axis (numeric calculations), ignoring the properties of the `<categories>` element if present in the data. CATEGORIES - This mode is the default mode of `xAxisLabelMode`. It allows the chart to show the properties of the `<categories> `element on the x-axis labels. MIXED - Allows the chart to show both the properties of y-axis (numeric calculations) and the `<categories>` element on the x-axis simultaneously.
staggerLines Number 2 or above If you've 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.
showValues Boolean 0/1 Sets the configuration whether data values will be displayed along with the data plot on chart.
showYAxisValues Boolean 0/1 FusionCharts XT y-axis 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. This attribute shows or hides the y-axis divisional lines and limits. The values of `showLimits` and `showDivLineValues`, if specified explicitly, overrides the value of this attribute.
showXAxisValues
Since 3.2.2
Boolean 0/1 FusionCharts XT x-axis is divided into horizontal 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 (x-axis) values or not. This attribute shows or hides the x-axis divisional lines and limits. When specified the values of `showVLimits` and `showVDivLineValues` overrides the value of this attribute.
showLimits Boolean 0/1 Whether to show chart limit values. If not specified `showYAxisValues` attribute overrides this value.
showVLimits
Since 3.2.2
Boolean 0/1 Whether to show chart limit values of the x-axis. If not specified `showXAxisValues` attribute overrides this value.
showDivLineValues Boolean 0/1 Whether to show div line values. If not specified `showYAxisValues` attribute over-rides this value.
showVDivLineValues
Since 3.2.2
Boolean 0/1 Whether to show vertical div line values. If not specified `showXAxisValues` attribute over-rides this value.
xAxisMinValue Number Numeric Value The bubble/scatter chart have both x and y axis as numeric. This attribute lets you explicitly set the x-axis lower limit. If you do not specify this value, FusionCharts XT will automatically calculate the best value for you.
xAxisMaxValue Number Numeric Value The bubble/scatter chart have both x and y axis as numeric. This attribute lets you explicitly set the x-axis upper limit. If you do not specify this value, FusionCharts XT will automatically calculate the best value for you.

yAxisMaxValue Number Numeric Value This attribute helps you explicitly set the upper limit of the chart. If you don't specify this value, it is automatically calculated by FusionCharts XT based on the data provided by you.
use3DLighting Boolean 0/1 Whether to use 3D Bubbles or 2D Bubbles.
bubbleScale Number 0-2 If you want to proportionately increase/decrease size of all the bubbles on the chart, you can use this attribute. A value of less than 1 (but greater than 0) will decrease all the bubble sizes and vice versa.
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.
xAxisValuesStep
Since 3.2.2
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 FusionCharts XT 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 will disable automatic adjustment of divisional lines.
adjustVDiv
Since 3.2.2
Boolean 0/1 FusionCharts XT automatically tries to adjust divisional lines and limit values of the x-axis based on the data provided. However, if you want to set your explicit lower and upper limit values and number of divisional lines for the x-axis, first set this attribute to false. That will 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've the special characters (UTF-8) in your y-axis name that do not show up in rotated mode.

Chart Padding & Margins

FusionCharts 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 FusionCharts 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, FusionCharts XT will not plot anything in that space.

It is not necessary for you to specify any padding/margin values. FusionCharts 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
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/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.

legendPadding Number In Pixels Padding of legend from right/bottom side of canvas
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. In case of 3D charts, the canvas box is the imaginary box around the 3D canvas. Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, FusionCharts XT 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've 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 doesn't 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.

<set> element

Each <set> element (child of the <dataset> 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 bubble chart, a typical <set> element will look like:

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

These attributes let you configure the <set> element.

Name Type Range Description

showValue Boolean 0/1 You can individually opt to show/hide values of individual data items using this attribute. This value over-rides the dataset level value.
alpha Number 0-100 For multi-series and combination charts, you can define the alpha of datasets at dataset level. However, if you wish to highlight a particular data element, you can specify its alpha at "set" level using this attribute.

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.

dashGap Number In Pixels If you've 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"
