A Pie chart is suitable for showing the distribution of a whole into parts (segments) corresponding to the frequency of a category or characteristic.

The following example shows the distribution of the produced product length (in total) related to the different materials used. The product length is selected under Columns and the material designation is selected as the Category. The pie chart shows the product lengths added up per material group within the considered time range in descending order.

Columns

Select the measured value or the value series whose distribution is to be displayed, e.g. the length of the produced material.
Group by Signal

Select the category to which the distribution refers, e.g. material thickness.
