How to create a pie chart with percentages of totals of columns

I’m new to grist and this seems trivial but I can’t seem to figure it out. I have the following data

  • Employee Name
  • Total Hours Worked
  • Hours worked in category 1
  • Hours worked in category 2
  • Hours worked in category 3

What I want is a pie chart with percentages of hours worked across all employees by category

What I did was put these all into columns, I then created a summary table for the totals of each category’s hours.

So now I have a summary table with the sum of total hours worked across all employees separated by category. All I want to do is take these 3 sums and stick them into a pie chart to get percentages, however it seems like pie charts don’t work this way. The data needs to be vertical not horizontal.

I tried to reference the summary data, and put it into a new table but I can’t do that either

Sample here.

As you define three different columns, I guess you have a defined number of categories (otherwise it would be far better to have a Name, Category, Hours scheme for your Example table). Then you can afford a Categories table with Category, Total hours columns. The Total hours column would be a formula column with this formula:

if $Category == 1:
  return sum(Example.all.Category_1)
elif $Category == 2:
  return sum(Example.all.Category_2)
elif $Category == 3:
  return sum(Example.all.Category_3)
