The size of pie charts differs based on the amount of labels attached to it (outside labels). This can be observed in this fiddle and the following image:
Of course, the available size for the chart differs based on how many labels are attached to the pie chart. However, this could be solved by introducing a fixed padding around the pie (the circle) which is reserved for labels even if the chart only has one label.
Adding such a padding will result in generally smaller pies (again, I’m referring to the circle) and seems to be a waste of space if you have only a single pie chart on a page. However, we have multiple pie charts on a single page and it would be great if they had a consistent size.
thank you for your response. I’m sorry that I missed this property. That should work!
Although it’s a little bit off-topic:
I used the 1.7.0 version from cdnjs because the latest version is only hosted here (canvasjs.com) via HTTP. This is blocked by my browser by default
Mixed Content: The page at ‘https://jsfiddle.net/canvasjs/dvdyfemg/2/’ was loaded over HTTPS, but requested an insecure script ‘https://canvasjs.com/assets/script/canvasjs.min.js’. This request has been blocked; the content must be served over HTTPS.
Of course, I can disable the blocking of scripts that are loaded via HTTP, but I assume that most others block the script too (I’m using Google Chrome version 51.0.2704.103) and therefore might not see the any results in the fiddle by default.
