ComponentOne Chart 8.0 for ActiveX

Pie Charts

A pie chart draws each series as a slice in a pie. The number of pies is the number of points in the data. Each pie displays the nth data point in each series. Using ChartStyles, you customize the fill properties of each series. You can also customize special pie properties and 3D display properties.

To Change the Chart Type

Use the ChartType property to set the chart type for one ChartGroup. ChartType is located on the General Tab (ChartGroups) on the Property Pages. Use the ChartType dropdown to select the appropriate chart.

Pie Chart 3D Effects

ComponentOne Chart’s 3D effects can be used with pie charts to create the illusion of depth. By using the Depth, Elevation, Rotation and Shading properties, you can enhance your pie charts, making them stand out by creating visual depth as shown below.

To access the 3D view for a pie chart, activate the Property Editor View3D Page. The General Tab (View3D) allows you to modify the Depth, Elevation, Rotation and Shading properties by typing a value in the appropriate textbox.

Note that the Depth property is the key to all 3D type chart logic. While the Elevation and Rotation properties modify the way a user views the chart, it is the Depth property that actually dictates whether a chart is 3D. By using a non zero value for the depth property and setting the elevation and rotation property values to zero, you have created a 3D chart even though nothing seems to have changed. In effect you are looking at the “top” surface of the chart which is visually represented in the same way as a standard pie chart.
