Interactive Pie chart (local)

KNIME Base Nodes version 4.0.2.v201909251340 by KNIME AG, Zurich, Switzerland

Displays an interactive pie chart with different viewing options. The interactive pie chart supports hiliting and the changing of the pie and aggregation column on the fly.

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:

  1. Pie column
  2. Aggregation column
  3. Aggregation method (count, summary, average)
  4. Pie size
  5. Show missing value section
  6. Show pie section outline
  7. Draw selected section exploded
  8. Show details for selected sections
  9. Set value scale to percentage or original
  10. Pie size
  11. Explode size
Each pie column value get its own colored section. Hiliting is supported.

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.

Please note: This node caches all data in the main memory to provide interactive functions. If you plan to visualize extremely large datasets the non interactive "Pie chart" node may be better suited.

The pie chart supports maximum 360 sections!
