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.

Attribute Name	Type	Description
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.
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 the Styles feature.
clickURL	URL in FusionCharts format	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.
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.
paletteThemeColor	Color 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., <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.
showRTMenuItem	Boolean (0/1)	Whether to show the real-time update related menu items (like Start/Stop Update or Clear Chart) in chart's context menu? Note: For JavaScript charts real-time update related menu items do not appear by default. You need to explicitly set showRTMenuItem='1' in <chart> element. The menu appears as a button on the bottom-left corner of the JavaScript chart. You can then use the button to Start/Stop Update or Clear chart.
showPrintMenuItem	Boolean (0/1)	Whether to show "Print Chart" item in the context menu of the chart? Even if you opt to hide the item in context menu, you can still opt to invoke print() JavaScript method of the chart to print the same.
showAboutMenuItem	Boolean (0/1)	Setting this to 1 displays a custom context menu in the chart; this can be customized to show your text and can be linked to your URL. For e.g., 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	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.

Plot fill properties like gradient color, angle etc. will not work anymore, as the colors for gradient are now calculated by the chart itself. Plot border properties also do not work in this mode. Also, you cannot render the border as dash in this mode.
refreshInstantly Since v 3.2	Boolean (0/1)	By default, the real-time charts wait for a few seconds after rendering for the first time and before updating itself with new data. To allow the chart to start updating itself as soon as it is rendered, set this attribute to 1.
stack100Percent Since v 3.2	Boolean (0/1)	Setting this attribute to 1 helps in depicting the values in percentage figures. When this attribute is set to 1 the chart considers the total of the stacked dataplot as 100% and the Y-Axis shows a scale from 0% to 100%.
showPercentValues Since v 3.2	Boolean (0/1)	Whether to show percentage figures in data values of the chart.
showPercentInToolTip Since v 3.2	Boolean (0/1)	Whether to show percentage figures in tooltip.

If you intend to specify font properties for individual chart elements (like Caption, sub-caption etc.), you'll need to use the Styles feature. Using Styles, you can also specify advanced font properties like Bold, Italics, HTML Mode etc. Using Styles you can also configure real-time values.

Attribute Name	Type	Description
baseFont	Font Name	This attribute lets you set the font face (family) of all the text (data labels, values etc.) on chart. If you specify outCnvBaseFont attribute also, then this attribute controls only the font face of text within the chart canvas bounds.
baseFontSize	Number	This attribute sets the base font size of the chart i.e., all the values and the names in the chart which lie on the canvas will be displayed using the font size provided here.
baseFontColor	Color Code	This attribute sets the base font color of the chart i.e., all the values and the names in the chart which lie on the canvas will be displayed using the font color provided here.
outCnvBaseFont	Font Name	This attribute sets the base font family of the chart font which lies outside the canvas i.e., all the values and the names in the chart which lie outside the canvas will be displayed using the font name provided here.

In multi-series charts, the series name of each data-set shows up in the legend of the chart. If you do not need the legend, you can opt to hide the same.

Also, the legend can be placed at the bottom of the chart or to the right of the chart.

Using the attributes below, you can configure the functional and cosmetic properties of the legend.

Attribute Name	Type	Description

The following attributes help you control chart margins and paddings.

FusionWidgets XT allows you 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.

It's not necessary for you to specify any padding/margin values. FusionWidgets XT automatically assumes the best values for the same, if you do not specify the same.

Attribute Name	Type	Description
captionPadding	Number (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 (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 (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 (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 (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 (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.
plotSpacePercent	Number (Percent) 20-80	On a column chart, there is spacing defined between two columns. By default, the spacing is set to 20% of canvas width. If you intend to increase or decrease the spacing between columns, you can do so using this attribute. For example, if you wanted all columns to stick to each other without any space in between, you can set plotSpacePercent to 0. Similarly, if you want very thin columns, you can set plotSpacePercent to its max value of 80.
realTimeValuePadding	Number (Pixels)	Vertical distance between the real-time value and x-axis labels.
legendPadding	Number (Pixels)	Padding of legend from right/bottom side of canvas
chartLeftMargin	Number (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 (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 (Pixels)	Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space.
chartBottomMargin	Number (Pixels)	Amount of empty space that you want to put on the bottom of your chart. Nothing is rendered in this space.
canvasLeftMargin	Number (Pixels)	Left margin of canvas. Canvas will start from that position.
canvasRightMargin	Number (Pixels)	Right margin of canvas. Canvas will end at that position.
canvasTopMargin	Number (Pixels)	Top margin of canvas.
canvasBottomMargin	Number (Pixels)	Bottom margin of canvas.

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.

Attribute Name	Type	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	Lets you specify font color for the x-axis data labels.
Back to top

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>).

You can specify the following attributes for <category> element:

Attribute Name	Type	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.

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.

In multi-series charts, it is used between <category> elements as under:

Attribute Name	Type	Description
label	String	Display label for the vLine.
color	Color Code	This attribute defines the color of vertical separator line.
thickness	Number (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 (pixels)	If the vertical separator line is to appear as dashed, this attribute defines the length of dash.
dashGap	Number (pixels)	If the vertical separator line is to appear as dashed, this attribute defines the length of dash gap.

Each <dataset> element contains a series of data.

For example, if we're plotting a performance chart for 2 processors, the first dataset will contain the data for Processor A and the next one for the Processor B.

You can provide dataset level cosmetics so that all data within that dataset will be plotted in the same color/alpha/etc.

Also, each dataset can be named using the seriesName attribute of <dataset> element. The series name appears in the legend of the chart.

Attribute Name	Type	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	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 border will appear as dashed?
Back to top

Each <set> element (child of <chart> or <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 multi-series chart, it could look like:

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

In multi-series charts, you should again note that the number of <category> elements should be equal to the number of data points in each data sets, i.e., if you mention twelve categories (twelve months), the data for both years (2005 & 2006) should also contain twelve <set> elements (twelve rows of data).

Attribute Name	Type	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	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 it's color at "set" level using this attribute. This attribute accepts hex color codes without #.
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.

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.

For each trend line on the chart, you need to define a <line> element under <trendLines> element as under:

<trendLines>
  <line startValue='895' color='FF0000' displayValue='Average' />
</trendLines>

You can control the cosmetic and functional properties of trend-lines using the following attributes:

Attribute Name	Type	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	Color of the trend line and its associated text.
thickness	Number (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 display a line or a zone (filled 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 (Pixels)	If you've opted to show trend line as dash, this attribute lets you control the length of each dash.
dashGap	Number (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.
