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.
paletteThemeColor Color Code Hex Code If you want your own palette derived from a particular hex color, you can specify the same here. All other colors on the chart will automatically derive from that palette.
paletteColors String List of hex color codes separated by comma 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 dataplots (i.e., column, line, area etc.). The `paletteThemeColor` attribute allows to specify your own palette derived from a particular hex color that is applied to chart background, canvas, font, tool-tips and also dataplots. Using `paletteColors` attribute, you can specify your custom list of hex colors for the dataplots only. 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.

Tool-tip Properties

These attributes let you configure the functional and cosmetic properties of tool-tips.

Name Type Range Description
showToolTip Boolean 0/1 Whether to show tooltip on chart?
seriesNameInToolTip Boolean 0/1 This attribute lets you control whether series name will show up in tooltip or not.
toolTipBgColor Color Code Hex Code Background color for tooltip.
toolTipColor Color Code Hex Code Font color for the tool-tip.
toolTipBorderColor Color Code Hex Code Border color for tooltip.
toolTipSepChar String The character specified as the value of this attribute separates the name and value displayed in tooltip.

Chart Paddings and Margins

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

It is not necessary for you to specify any padding/margin values. FusionWidgets 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.
canvasPadding Number In pixels Lets you set the space between the canvas border and first & last data points
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.
valuePadding Number In pixels It sets the vertical space between the end of columns and start of value textboxes. This basically helps you control the space you want between your columns/anchors and the value textboxes.
realTimeValuePadding Number In pixels Vertical distance between the real-time value and x-axis labels.
legendPadding Number In pixels Padding of legend from right/bottom side of canvas.
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 Left margin of canvas. Canvas will start from that position.
canvasRightMargin Number In pixels Right margin of canvas. Canvas will end at that position.
canvasTopMargin Number In pixels Top margin of canvas.
canvasBottomMargin Number In pixels Bottom margin of canvas.

The <categories> Element

The <categories> element lets you bunch together x-axis labels of the chart. For a multi-series chart, it's necessary to provide data labels using <category> elements under <categories> element. The following properties of <categories> element help you control the font properties of data labels.

Name Type Range Description
font String Lets you specify font face for the x-axis data labels.
fontSize Number Lets you specify font size for the x-axis data labels.
fontColor Color Code Hex Code Lets you specify font color for the x-axis data labels.

The <category> Element

Each <category> element represents an x-axis data label. In multi-series charts, it's necessary to provide an equal number of <category> elements and data items (<set> elements within each <dataset>).

These attributes let you configure the <category> element.

Name Type Range Description
label String This attribute determines the label for the data item. The label appears on the x-axis of chart.
showLabel Boolean 0/1 You can individually opt to show/hide labels of individual data items using this attribute.
tooltext String The tooltip defined in the `<category>` element appears only when the mouse cursor is hovered over the data plots. 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 dataplot.

Vertical Data Separator Lines

vLines are vertical separator lines that help you separate blocks of data. These lines run through the height of the chart, thereby segregating data into different blocks.

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

    "data": [{
        ...
    },
    {
        "linePosition": "0.8",
        "vLine": "true"
    },
    ...

These attributes let you configure the functional and cosmetic properties for vertical trend-lines and trend-zones.

Name Type Range Description
label String Display label for the vLine.
color Color Code Hex Code This attribute defines the color of vertical separator line
thickness Number In pixels Thickness in pixels of the vertical separator line.
alpha Number 0-100 Alpha of the vertical separator line.
dashed Boolean 0/1 Whether the vertical separator line should appear as dashed?
dashLen Number In pixels If the vertical separator line is to appear as dashed, this attribute defines the length of dash.
dashGap Number In pixels If the vertical separator line is to appear as dashed, this attribute defines the length of dash gap.

The <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 attributes let you customize the cosmetic properties for a data-set.

Name Type Range Description
seriesName String Lets you specify the series name for a particular dataset. For example, if you're plotting a chart to indicate monthly sales analysis for 2005 and 2006, the `seriesName` for the first dataset will be 2005 and that of the second will be 2006. The `seriesName` of a dataset is shown in legend.
color Color Code Hex Code This attribute sets the color using which columns, lines, area of that dataset will be drawn. For column chart, you can specify a list of comma separated hex codes to get a gradient plot
alpha Number 0-100 This attribute sets the alpha (transparency) of the entire dataset.
showValues Boolean 0/1 Whether to show the values for this dataset?
includeInLegend Boolean 0/1 Whether to include the `seriesName` of this dataset in legend? This can be particularly useful when you're using combination charts and you've used the area/line chart to plot a trend and you do not want the `seriesName` of that trend to appear in legend.
checkForAlerts Boolean 0/1 Whether to run the values of this dataset through alert manager, each time an update is received?
dashed Boolean 0/1 Whether this dataset will appear as dashed?
lineDashLen Number In pixels If the lines are to be shown as dash for the particular dataset, this attribute defines the length of dash.
lineDashGap Number In pixels Sets the gap between two consecutive dashes.

drawAnchors Boolean 0/1 Whether to draw anchors for the particular dataset? If the anchors are not shown, then the tooltip and links won't work for the dataset.
anchorSides Number 3-15 Sets the number of sides that the anchors of the particular dataset will have. For e.g., an anchor with 3 sides will represent a triangle, with 4 it will be a square and so on.
anchorRadius Number In pixels This attribute sets the radius (in pixels) of the anchors of the particular dataset.
anchorBorderColor Color Code Hex Code Lets you set the border color of anchors of the particular dataset.
anchorBorderThickness Number In pixels Helps you set border thickness of anchors of the particular dataset.
anchorBgColor Color Code Hex Code Helps you set the background color of anchors of the particular dataset.
anchorAlpha Number 0-100 Helps you set the alpha of entire anchors of the particular dataset. If you need to hide the anchors for the dataset but still enable tool tips, set this as 0.
anchorBgAlpha Number 0-100 Helps you set the alpha of anchor background of the particular dataset.
valuePosition
Since 3.2
String "ABOVE", "BELOW", "AUTO" This attribute lets you adjust the vertical alignment of data values for all the dataplots in the dataset. The alignment is set with respect to the position of the dataplots on the chart. By default, the attribute is set to AUTO mode in which the alignment of each data value is determined automatically based on the position of each plot point. In ABOVE mode, data values are displayed above the plot points unless a plot point is too close to the upper edge of the canvas. While in BELOW mode, data values are displayed below the plot points unless a plot point is too close to the lower edge of the canvas. The attribute will function only if `showValue` attribute is set to 1 in this particular dataset.

The <set> Element

Each <set> element (child of <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 single series chart, a typical <set> element will look like:

<set label='January' value='17400' />

These attributes let you configure individual data values in a data-set.

Name Type Range Description
value Number Numerical value for the data item. This value will be plotted on the chart.
link String You can define links for individual data items. That enables the end user to click on data items (columns, lines, bars, etc.) 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 Drill-Down charts section for more information. Also, you'll need to URL Encode all the special characters (like ? and &) present in the link.
toolText String By default, FusionWidgets XT shows the "`label`, `value`" as tooltip text for that data item. But, if you want to display more information for the data item as tooltip, you can use this attribute to specify the same.
color Color Code Hex Code For multi-series charts, you can define the color of datasets at dataset level. However, if you wish to highlight a particular data element, you can specify its color at "set" level using this attribute.
alpha Number 0-100 For multi-series 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.
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.
dashed Boolean 0/1 Whether the border of this data item should appear as dashed? This is particularly useful when you want to highlight a data (such as forecast or trend etc.). This value over-rides the dataset level value.
anchorSides Number 3-15 Lets you specify "set" specific sides of the anchor.
anchorRadius Number In pixels Lets you specify "set" specific radius (in pixels) of the anchor.
anchorBorderColor Color Code Hex Code Lets you specify "set" specific border color of the anchor.
anchorBorderThickness Number In pixels Lets you specify "set" specific border thickness of the anchor.
anchorBgColor Color Code Hex Code Lets you specify "set" specific background color of the anchor.
anchorAlpha Number 0-100 Lets you specify "set" specific alpha of the anchor.
anchorBgAlpha Number 0-100 Lets you specify "set" specific alpha of the anchor background.
valuePosition
Since 3.2
String "ABOVE", "BELOW", "AUTO" If you've opted to show a particular data value on the chart, this attribute lets you adjust the vertical alignment of individual data values with respect to dataplots. By default, this attribute is set to AUTO mode in which the alignment of a data value is determined automatically based on the position of its plot point. In ABOVE mode, a data value is displayed above the plot point unless a plot point is too close to the upper edge of the canvas while in BELOW mode, a data value is displayed below the plot point unless a plot point is too close to the lower edge of the canvas.

Trend-lines

Using the <trendlines> element (and the 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 horizontal trend-line on the chart:

    ...
    "chart": {
                ...
        };

    "trendlines": [{
          "line": [{
              "startvalue": "177500",
              "color": "#00cc00",
              "displayvalue": "Target"
         }]
    }]

    ...

These attributes let you customize the functional and cosmetic properties for trend-lines.

Name Type Range Description
startValue Number The starting value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `startValue` will be 102.
endValue Number The ending y-axis value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `endValue` will be 109. If you do not specify a value for `endValue`, it will automatically assume the same value as `startValue`.
displayValue String 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 Color Code Hex Code Color of the trend line and its associated text
thickness Number In pixels If you've opted to show the trend as a line, this attribute lets you define the thickness of trend line.
isTrendZone Boolean 0/1 Whether the trend will be displayed as a line or a zone (fill-colored rectangle).
alpha Number Alpha of the trend line.
showOnTop Boolean 0/1 Whether the trend line/zone will be displayed over data plots or under them?
dashed Boolean 0/1 If you've opted to show the trend as a line, this attribute lets you define whether the trend line will appear as dashed?
dashLen Number In pixels If you've opted to show trend line as dash, this attribute lets you control the length of each dash.
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.
