The abstract chart expression is at the top of the hierarchy. Therefore, it follows that it contains properties that can be applied to all of the different chart types.

AbstractChartExpression Properties

Property Name	Data Type	Description
antiAlias	Boolean (true/false)	Anti-aliasing is a technique of minimizing aliasing (jagged or blocky patterns) when plotting images. Default is true.
backgroundColor	String	Sets the color of the background of the chart. It is a color in either HTML notation (like #80f000), or one of the w3c defined color names (like "cadet blue").
backgroundImage	String	Defines an image that's used in rendering the chart background. The image specified needs to be relative to the solution root. Example that loads an image from the test solution in the charts folder within that solution. <property name="backgroundImage">test/charts/ChartBackground.jpg</property>
borderColor	String	Sets the color of the border, if showBorder is set to true. It is a color in either HTML notation (like #80f000), or one of the w3c defined color names (like "cadet blue").
chartHeight	Integer	Height of the chart graphic in pixels.
chartSectionOutline	Boolean (true/false)	If true, draws each chart section with an outline stroke. Default: false
chartWidth	Integer	Width of the chart graphic in pixels.
dataSource	A xxxSetCollector function - see above	Before the chart can be rendered, it must have data collected by one of the available collector functions. This needs to be the name of the xxxSetCollectorFunction in the report document.
drawLegendBorder	Boolean (true/false)	If showLegend is true, draws a border around the legend. Default: true
labelFont	String	Font for the labels. The format for the font is as follows: fontfamilyname-style-pointsize Style can be one of: BOLD, BOLDITALIC, or ITALIC Example: Arial-BOLD-14 Default: SansSerif8
legendFont	String	The font used on the legend. The format for the font is as follows: fontfamilyname-style-pointsize Style can be one of: BOLD, BOLDITALIC, or ITALIC Example: Arial-BOLD-14 Default: SansSerif8
legendLocation	String	Used for placing the legend, if showLegend is true. Valid values: left, west, right, east, top, north, bottom, south. Note that left and west are the same as are the other pairs. Default depends on the JFreeChart default settings.
noDataMessage	String	Sets the message that displays if the chart has no data to display. This message appears in the center of the plot area.
showBorder	Boolean (true/false)	If true, the chart will have a border around it.
showLegend	Boolean (true/false)	If true, shows the legend on the chart.
threeD	Boolean (true/false)	If true, the chart is rendered in 3D (with shading and an apparent thickness). Default: false
title	String	The chart title.
titleFont	String	The font for the chart title. The format for the font is as follows: fontfamilyname-style-pointsize Style can be one of: BOLD, BOLDITALIC, or ITALIC Example: Arial-BOLD-14 Default: SansSerif-BOLD-14
useDrawable	Boolean (true/false)	Determines how the chart gets returned to the JFreeReport engine. If false, then the chart image is rendered in a file for use with the image-url function in the chart. Note that with HTML reports, using drawable is not useful unless the HTML File System in place is something other than the StreamHTMLFileSystem (the default in Pentaho). UPDATE: As of version 1.6, useDrawable should ALWAYS be true, as the image-url field no longer supports input from the chart expressions. Default: true
chartDirectory DEPRECATED as of 1.6	String	Specifies the folder into which the charts will be generated. Defaults to the system/tmp folder within the root solution.
chartFile DEPRECATED as of 1.6	String	Provides the ability to tell the engine the name of the file to generate. By default, the engine generates a temporary file.
returnFileNameOnly DEPRECATED as of 1.6	Boolean	If true, the function will only return the name of the file that was generated. Default: false
chartUrlMask DEPRECATED as of 1.6	String	Specifies a URL containing a replaceable marker ({0}) for the file name. This is useful when the chart image is generated into a folder, and a different webserver is used to serve up the chart images.
