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.

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.

These attributes let you configure how your line plot would appear on the chart.

If the plots can show borders, you can control the border properties using the attributes listed below. Or, if they support gradient fills, you can again configure various properties of the gradient using these attributes.

Various other controls over plot cosmetics can be attained using this set of attributes.

On Line charts, anchors (or marker points) are polygons which appear at the joint of two consecutive line points. These are indicators to show the position of data points.

The anchors handle tool tips and links for the data points. So, if you opt to not render anchors on a chart, the tool tips and links won't function. You can, however, hide them by setting alpha to 0 and still enable tool tips and links.

You can customize all the facets of anchors using the properties below.

Using this set of attributes, you can control the properties of divisional lines, zero plane and alternate color bands.

Divisional Lines are horizontal or vertical lines running through the canvas. Each divisional line signifies a smaller unit of the entire axis thus aiding the users in interpreting the chart.

The zero plane is a 2D plane that signifies the 0 position on the chart. If there are no negative numbers on the chart, you won't see a visible zero plane.

Alternate color bands are colored blocks between two successive divisional lines.

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.

PowerCharts 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 would round to
• Scaling of numbers based on a user defined scale
• Custom number input formats

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 PowerCharts XT. Using Styles, you can also specify advanced font properties like Bold, Italics, HTML Mode etc.

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

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, until 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.

The <categories> element lets you bunch together x-axis labels of the chart. For a Multi-series chart, it is 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.

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

In Multi-axis Line charts, it is necessary to provide an equal number of <category> elements and data items (<set> elements within each <dataset>). PowerCharts 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 are 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 Multi-axis Line 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 <axis> element on the Multi-axis Line chart represents an axis. An axis can either be visible or imaginary. Imaginary axis are the ones that do not show up on the chart, but can have data sets that adhere to the same.

Visible axis can be placed either to the left or right side of canvas.

For each axis, you can define a lot of properties like:

• Its lower and upper limits.
• Cosmetic properties.
• Number of divisional lines and their functional and cosmetic properties.
• Line properties for the datasets that adhere to this particular axis
• Number formatting properties

Each <dataset> element contains a series of data.

For example, if we are plotting a Monthly Sales comparison chart for two successive years, the first data-set would contain the data for first year and the next one for the second year.

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

Also, each data-set can be named using the seriesName attribute of <dataset> element. The series name appears in the legend of the chart. In our previous example, the series name could have well been 2005 and 2006 for first and second data-set respectively.

Depending on the chart type, there are a number of properties which you can define for each <dataset> element.

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 Multi-axis Line chart, it could look like:

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

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

The chart also accepts the following features, which have not been discussed here:
