Formatting a pie or doughnut chart
When you format a pie or a doughnut chart, you specify a chart title, size, dimension, angle of rotation, radius of the pie or width of the doughnut ring, font, and legend properties.
To format a pie chart, in addition to specifying the title, size, dimension, and legend, you can set the following options shown in Figure 8‑90:
1 Specify the rotation angle in degrees.
Figure 8‑90 displays an angle of rotation of 180 degrees.

2 Specify the size of the pie:
*Select Auto Radius to enable BIRT Studio to set a radius for the pie, as shown in Figure 8‑90.
*Deselect Auto Radius, then specify the size of the pie in pixels.
3 Specify font properties using the drop‑down lists to set font type, size, and color.
Figure 8‑91 shows the additional formatting options available when you format a doughnut Flash chart.

You can specify the width of the doughnut ring as follows:
*Accept the default selection of Auto Outer Radius and Auto Inner Radius to enable BIRT Studio to determine the width of the doughnut, as shown in Figure 8‑91.
*Specify a different value after first deselecting Auto Outer Radius and Auto Inner Radius, by using the menus to set the width of the doughnut.
