Group "others" in Pie Charts for Executive Dashboard

Here is the case study I’m trying to fix:

I have a few pie charts that show customer detail, very helpful until you start believing the percentages listed on the pie chart. The pie chart below is 2025 Fiscal YTD Bookings by parent customer. The pie chart automatically limits it to top 25 customers. The percentages shown are the value of each customer to the top 25, not the % to the whole company. For instance, “Blue Customer” (BC) is shown in blue and at 37%. This shows they are 37% of the top 25 customers, when they are 33% of the total company. If I change the pie chart to show top 10, BC becomes 46%. Quite a different story line when talking about customer concentration.

Some pie chart software have an “other” bucket to allow the percentages to properly calculate. In my online searches, some places said that EDA pie charts have a “group remaining items as others” for customers outside the top 25 shown. They all mentioned that EDA had a higher “designer” access beyond Administrator, but as with anything, it might be an older version of EDA with that functionality gone or a different version.

Would be nice to to not explain to CEO that EDA pie charts don’t show correct percentages in charts.
