List of available chart types

Below is a list of all available chart types, notice not all are available in the chart type menu. Why? We disabled the 3D options b/c we discovered that they are not best practices, and do not help communicate meaning, they're just there for flash:

• case 1: BarChart
• case 2: BarChart3D
• case 3: BarChart
• case 4: BarChart3D
• case 5: StackedBarChart
• case 6: StackedBarChart3D
• case 7: StackedBarChart
• case 8: StackedBarChart3D
• case 9: LineChart - vert
• case 10: LineChart - horiz
• case 11: AreaChart - vert
• case 12: AreaChart - horiz
• case 13: StackedAreaChart - vert
• case 14: StackedAreaChart - horiz
• case 15: PieChart - by column
• case 16: PieChart - by row
• case 17: 3DPieChart - by column
• case 18: 3DPieChart - by row

So what if you still want to enable the missing types?

chart properties form

Edit the chart properties form (http://cvs.sourceforge.net/viewcvs.py/openi/openi/web/WEB-INF/openi/chart/chartpropertiesform.xml?rev=1.2&view=markup), add the missing types with your desired label:

   <listBox1 type="int" modelReference="chartType">
	<listItem value="1" label="Vertical Bar"/>
	<listItem value="3" label="Horizontal Bar"/>
	<listItem value="5" label="Stacked Vert Bar"/>
