 <chart> element Attributes

Functional Attributes

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

Attribute 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 Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme. Valid values are 1-5.
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,
<chart 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 XML.
showAboutMenuItem Boolean 0/1 Setting this to 1 shows up a custom context menu in the chart, which can be customized to show your text and can be linked to your Url. For example, you can set the context menu of the chart to include "About your company name" and then link to your company home page. By default, the chart shows "About FusionCharts" when right clicked.
aboutMenuItemLabel String   The menu item label for the custom context menu item.
aboutMenuItemLink String URL Link for the custom context menu item. You can specify the link in FusionCharts Link Format to be able to open the same in new window, pop-ups, frames or as JavaScript links.
showLabels Boolean 0/1 It sets the configuration whether the x-axis labels will be displayed or not.
xAxislabelDisplay String AUTO              Since v 3.2
WRAP
STAGGER
ROTATE or
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.
maxLabelWidthPercent Numeric In Pixels Restricts the maximum space allotted for the y-axis data labels with respect to the chart's width. If a data label is longer than the specified percentage width then it will either be wrapped or get truncated, subject to the availability of vertical space. Unnecessary space is not reserved for the labels. If all the labels are shorter than the specified maximum width, this value is not applied.
useEllipsesWhenOverflow 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.
trType String   Specifies the type of data provided in the top-right label. This value is displayed in the tool tip.
tlType String   Specifies the type of data provided in the top-left label. This value is displayed in the tool tip.
brType String   Specifies the type of data provided in the bottom-right label. This value is displayed in the tool tip.
blType String   Specifies the type of data provided in the bottom-left label. This value is displayed in the tool tip.
showTooltipforWrappedLabels Boolean 0/1 When the labels of the chart are too lengthy, the chart truncates them and displays a part of the label. In this situation, this attribute shows a tooltip displaying the complete label when the mouse is hovered on the shortened labels.
rotatexAxisLabels Boolean 0/1 This attribute lets you set whether the data labels would show up as rotated labels on the chart.
slantxAxisLabels 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.
xAxislabelStep 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.
yAxislabelStep Number 1 or above By default, all the labels are displayed on the y axis of 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.
showYaxisLabels Boolean 0/1 This attribute is used to show or hide y axis or the row labels.
showXaxisLabels Boolean 0/1 This attribute is used to show or hide the x axis or the column labels.
staggerxAxisLines 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.
showValues Boolean 0/1 Sets the configuration whether data values would be displayed along with the data plot on chart.
rotateValues Boolean 0/1 If you have opted to show data values, you can rotate them using this attribute.
showLimits Boolean 0/1 Whether to show chart limit values.
showDivLineValues Boolean 0/1 Whether to show div line values.

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.
defaultAnimation Boolean 0/1 By default, each chart animates some of its elements. If you wish to switch off the default animation patterns, you can set this attribute to 0. It can be particularly useful when you want to define your own animation patterns using Styles feature.
interactiveAnimationDuration Number Sets the duration of the animation that takes place when the legends are used to show or hide dataplots.
mapByCategory Boolean 0/1 Allows you to render a category based heat map chart.
showHoverEffect Boolean 0/1 Sets a style effect on the dataplots when the mouse is hovered on the dataplots. By default, it shows a bevel effect.
plotFillAlpha Numeric 0-100 Sets the transparency of all the dataplots in the chart.
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'.
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.
centerYaxisName

Chart Padding & Margins

The following attributes help you control chart margins and paddings.

PowerCharts XT allows you 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 would not plot anything in that space.

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

Attribute 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).
labelxPadding Number In Pixels This attribute sets the vertical space between the x-axis labels and canvas bottom edge.
labelyPadding Number In Pixels It sets the horizontal space between the y-axis labels and the canvas right edge.
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 on the bottom of your chart. Nothing is rendered in this space.
legendPadding Number In Pixels Padding of legend from right or 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.

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.
