I found a really weird issue with tool tips and pie charts today. I’ve found two numbers that completely break the tool tips on my pie charts (2610,1527). Now these numbers only seem to break the tool tip for the pie chart if they are 100%, meaning all other data points are 0. I used the demo on this site as a catalyst for this bug report. Adding a value to any other data point and the tool tip shows.
