Pie chart
Displays a pie chart with different viewing options. Hiliting and
changing of the pie and aggregation column on the fly is only supported
by the interactive pie chart.
If the pie chart appears in gray no color information is set
for the selected pie column. Use the 'Color Manager' node in order
to set the color appropriate.
The user can change the following view properties on the fly:
- Aggregation method (count, summary, average)
- Pie size
- Show missing value section
- Show pie section outline
- Draw selected section exploded
- Show details for selected sections
- Set value scale to percentage or original
- Pie size
- Explode size
Each distinct pie column value get its own colored section.
Color selected sections:
If the color selected sections option is selected the pie displays also sub
sections for the selected sections. A sub section represents the rows
color using the color manager. This option is only available if
row colors are set.
This view is particularly well suited for extremely large datasets.
For more interaction and hiliting support use the
"Pie chart (interactive)" node.
The pie chart supports maximum 360 sections!
