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.

Using these attributes, you can set the various headings and titles of chart like caption, sub-caption, x-axis and y-axis names etc.

The following attributes let you configure chart cosmetics like background color, background alpha, canvas color & alpha etc.

FusionCharts XT 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 will round to
• Scaling of numbers based on a user defined scale
• Custom number input formats

These attributes let you control the tool tip. You can set the background color, border color, separator character and few other details.

Each <category> element represents an x-axis data label.

In stacked charts, it's necessary to provide an equal number of <category> elements and data items (<set> elements within each <dataset>). FusionCharts XT plots only those data items for which it could find a respective <category> element.

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

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.

For example, if you're plotting a chart showing monthly sales from October 2005-Mar 2006, you might want to plot a vertical separator line between Dec 2005 and January 2006 to indicate end of year.

In stacked charts, it is used between <category> elements as under:

<categories>
   <category label='Oct 2005' />
   <category label='Nov 2005' />
   <category label='Dec 2005' />
   <vLine color='FF5904' thickness='2' />
   <category label='Jan 2006' />
   <category label='Feb 2006' />
</categories>

You can configure the cosmetics of vertical separator lines using the following attributes:

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 stacked chart, it could look like:

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

In stacked 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).

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:
