Class BarRendererProcessor

java.lang.Object
  de.laures.cewolf.cpp.BarRendererProcessor

All Implemented Interfaces:

ChartPostProcessor, java.io.Serializable

public class BarRendererProcessor
extends java.lang.Object
implements ChartPostProcessor, java.io.Serializable

A postprocessor for setting/removing the bar outline (default: false), the item margin for 2D and 3D bar charts (default: 0.2%), whether or not item labels are visible (default: no), the color to use for item labels (default: black) and their font size (default: 12). It also has an option to set custom category colors (as opposed to custom series colors, which is what the SeriesPaintProcessor provides); if you use this you'll want to set showlegend=false.

Usage:

<chart:chartpostprocessor id="barRenderer">
<chart:param name="outline" value="true"/>
<chart:param name="itemMargin" value="0.1"/>
<chart:param name="showItemLabels" value="true"/>
<chart:param name="itemLabelColor" value="#336699" />
<chart:param name="itemLabelSize" value="14" />
<chart:param name="categoryColors" value="true"/>
<chart:param name="0" value="#FFFFAA" />
<chart:param name="1" value="#AAFFAA" />
<chart:param name="2" value="#FFAAFF" />
<chart:param name="3" value="#FFAAAA" />
</chart:chartpostprocessor>
