Hi all,
I am working on three different pie chart which show the market share of the same products in different time periods. I would like to maintain the same color for the same product in each pie chart. I am filling the "arraytodatatable" of each chart with the same products in the same order but some product has the value 0 for different time period.
When the charts are shown the color are assigned for the slices which are visible (> 0) and the color assignement is not the same for the same product.
Is there a way to consider the o valued product/time period also when the value is 0 to maintain the same color per product?
I would not like to static define colors due to the fact the number of products may vary in the future.
Thank you,
