Two value columns in one pie chart and insertion of characters

[Anonymous]

Hi,

from a table should be displayed in a pie chart two columns, “value1” and “value2”. How can it changed between two values in a chart, so there is one chart?

How can characters/values replace with blank spaces in a table. Quantity of charakters are in column ShowFlag.

structure               value1

world                     88700

   asia                       200000

   africa                     139000

   eastamerica           79000
