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	Range	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.
palette	Number	1-5	FusionCharts introduces 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. 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 (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., <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.

startingAngle	Number	0-360	By default, the pie chart starts from angle 0 i.e., the first pie starts plotting from 0 angle. If you want to change the starting angle of the chart, use this attribute.
enableRotation	Boolean	0/1	The doughnut/pie charts have three modes: Slicing, Rotation and Link. If any links are defined, the chart works in Link mode. Otherwise, it starts in Slicing mode. If you need to enable rotation by default, set this attribute to 1.

The pie and doughnut charts can have smart labels and lines.

Smart labels/lines are data connector lines, which connect the pie/doughnut slices to their respective labels without over-lapping even in cases where there are lots of labels located near each other.

You can configure the smart labels/lines properties using the attributes below.

Attribute Name	Type	Range	Description
enableSmartLabels	Boolean	0/1	Whether to use smart labels or not?

smartLabelClearance	Number	In Pixels	Clearance distance of a label (for sliced-in pies) from an adjacent sliced out pies.
manageLabelOverflow	Boolean	0/1	This attribute tries to manage overflow of data labels. If enabled, data labels are either wrapped or truncated with ellipses to prevent them from overflowing out of the chart canvas. In case smartLabels is disabled, the labels are wrapped to avoid the overflow. Since smartLabels is disabled, the wrapped labels might get overlapped. When smartLabels is enabled, management of the overflowing labels fit in the "quadrant specific smart labeling algorithm". Data labels try to wrap first. In case, there is constrain of space in the quadrant, the labels get truncated with ellipses.
useEllipsesWhenOverflow Since v1.3	Boolean	0/1	When enabled, long data labels are truncated by adding ellipses to prevent them from overflowing the chart background. The default value is 1. This setting works only when manageLabelOverflow is set to 1.

FusionCharts offers you a lot of options to format your numbers on the chart.

Using the attributes below, you can control a myriad of options like:

Formatting of commas and decimals

Number prefixes and suffixes

Decimal places to which the numbers would round to

Scaling of numbers based on a user defined scale

Custom number input formats

Attribute Name	Type	Range	Description
formatNumber	Boolean	0/1	This configuration determines whether the numbers displayed on the chart will be formatted using commas, e.g., 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 - e.g., if formatNumberScale is set to 1, 1043 would become 1.04K (with decimals set to 2 places). Same with numbers in millions - a M will added at the end. For more details, please see Advanced Number Formatting section.
defaultNumberScale	String		The default unit of the numbers that you're providing to the chart. For more details, please see Advanced Number Formatting section.
numberScaleUnit	String		Unit of each block of the scale. For more details, please see Advanced Number Formatting section.

For example, to represent all dollars figure on the chart, you could specify this attribute to ' $' to show like $40000, $50000. For more details, please see Advanced Number Formatting section.
numberSuffix	String	Character	Using this attribute, you could add suffix to all the numbers visible on the graph. For example, to represent all figure quantified as per annum on the chart, you could specify this attribute to ' /a' to show like 40000/a, 50000/a. For more details, please see Advanced Number Formatting section.
decimalSeparator	String	Character	This option helps you specify the character to be used as the decimal separator in a number. For more details, please see Advanced Number Formatting section.
thousandSeparator	String	Character	This option helps you specify the character to be used as the thousands separator in a number. For more details, please see Advanced Number Formatting section.
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 a error while converting to number. So, FusionCharts accepts the input decimal and thousand separator from user, so that it can covert it accordingly into the required format. This attribute lets you input the decimal separator. For more details, please see Advanced Number Formatting section.
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 a error while converting to number. So, FusionCharts accepts the input decimal and thousand separator from user, so that it can covert it accordingly into the required format. This attribute lets you input the thousand separator. For more details, please see Advanced Number Formatting section.
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 limit the maximum number of decimal digits to 2, a number like 55.345 will be rounded to 55.34. This does not mean that all numbers will be displayed with a fixed number of decimal places. For instance 55 will not be displayed as 55.00 and 55.1 will not become 55.10. In order to have fixed number of decimal places attached to all the numbers, set this attribute to 1. For more details, please see Advanced Charting > Number Formatting > Basics page.

Using the attributes below, you can define the generic font properties for all the text on the chart. These attributes allow you a high level control over font properties.

If you intend to specify font properties for individual chart elements (like Caption, sub-caption, etc.), you need to use the STYLES feature of FusionCharts. Using STYLES, you can also specify advanced font properties like Bold, Italics, HTML Mode, etc.

The following attributes help you control chart margins and paddings.

FusionCharts lets you customize the padding of various elements on the chart manually that allows advanced manipulation and control over chart visualization. Padding in FusionCharts 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 wouldn't plot anything in that space.

It's not necessary to specify any padding/margin values. FusionCharts automatically assumes the best values for the same, if not specified.

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.
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.

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 would appear on the chart.

For a single series chart, a typical <set> element would look like:
<set label='January' value='17400' />

For a multi-series chart, it would look like:
<dataset seriesName='2006'>
<set value='35445' />
<set value='35675' />
.... and so on ....
</dataset>

In multi-series/combination 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	Range	Description

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'll need to URL Encode all the special characters (like ? and &) present in the link.
toolText	String		By default, FusionCharts shows the data item name and value as tool tip text for that data item. But, if you want to display more information for the data item as tool tip, you can use this attribute to specify the same.
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.).
alpha	Number	0-100	This attribute determines the transparency of a data item. The range for this attribute is 0 to 100. 0 means complete transparency (the data item won?t be shown on the graph) and 100 means opaque.
