## XML Attributes for Data Plot
Plot refers to the column, lines etc. in a column, line chart respectively.
Applying common gradient
Using the plotGradientColor attribute, you can globally add a gradient color to the entire plot (column, area) of chart by specifying a color as its attribute. For example, if you want to set #333333 as the common gradient color for all the columns in a 2D column chart, your data would be as under:
<chart plotGradientColor='333333' ....> <set label='Jan' value='420000' /> <set label='Feb' value='910000' /> <set label='Mar' value='720000' /> .... </chart>
By default, the columns have FFFFFF as the plot gradient color. In case you wish to use solid fills for the column, you have to use the plotGradientColor attribute without any color defined for it, i.e. plotGradientColor=''.
Controlling gradient properties
The plot gradient properties can be controlled using the following attributes:
Attribute Name | Range | Description
plotFillAngle | 0-360 | If you've opted to fill the plot (column, area etc.) as gradient, this attribute lets you set the fill angle for gradient.
plotFillRatio | 0-100 | If you've opted to fill the plot (column, area etc.) as gradient, this attribute lets you set the ratio for gradient.
plotFillAlpha | 0-100 | If you've opted to fill the plot (column, area etc.) as gradient, this attribute lets you set the fill alpha for gradient.
<chart plotGradientColor='333333' plotFillRatio='80,20' plotFillAlpha='95,100' plotFillAngle='45'>
Note that we have specified 2 values for plotFillRatio and plotFillAlpha. This is because one of the values specified is taken by the color specified for the column (or taken by default from the color palette) and the other one by the common gradient color specified using plotGradientColor attribute.
Plot border
By default, each data plot (column, area, pie etc) shows a border around it. You can hide the same using showPlotBorder='0'.
<chart showPlotBorder='0' ....> <set label='Jan' value='420000' /> <set label='Feb' value='910000' /> <set label='Mar' value='720000' /> .... </chart>
Dashed Plot border
You can make the plot border dashed using plotBorderDashed='1'. The dash length & gap can be customized using the plotBorderDashLen and plotBorderDashGap attributes respectively.
<chart plotBorderDashed='1' plotBorderDashLen='2' plotBorderDashGap='2' ...>
The above XML would yield the following chart:
Using Styles to provide effects to data plot
Using Styles, you can apply effects like shadow, glow, bevel and blur to the data plot. In the XML given below, we have given a bevel and shadow effect to the columns in a column chart.
The XML going into the same is:
<chart caption='Monthly Revenue' xAxisName='Month' yAxisName='Revenue' numberPrefix='$' showValues='0'> <set label='Jan' value='420000' /> <set label='Feb' value='910000' /> <set label='Mar' value='800000' /> <set label='Apr' value='550000' /> <set label='May' value='810000' /> <set label='Jun' value='510000' /> <styles> <definition> <style name='myBevel' type='bevel' distance='3'/> <style name='myShadow' type='shadow' angle='45' distance='3'/> </definition> <application> <apply toObject='DATAPLOT' styles='myBevel, myShadow' /> </application> </styles> </chart>
Applying animation using STYLES
You can customize animation of the data plot using STYLES. Given below is an XML which renders fade-in effect for columns, lines etc.
<chart caption='Monthly Revenue' xAxisName='Month' yAxisName='Revenue' numberPrefix='$' showValues='0'> <set label='Jan' value='420000' /> <set label='Feb' value='910000' /> <set label='Mar' value='800000' /> <set label='Apr' value='550000' /> <set label='May' value='810000' /> <set label='Jun' value='510000' /> <styles> <definition> <style name='myAnim' type='animation' param='_alpha' start='0' duration='2'/> <application> <apply toObject='DATAPLOT' styles='myAnim' /> </application> </styles> </chart>
