Hi!
I am trying to create a pie chart and increase the precision of the percentage to two decimals but it gives an error even for the simplist example as below.
X = [1/3 2/3];
pie(X,'%.3f%%')
Error using pie (line 71)
X and EXPLODE must be the same length.
line 71 [[sliceCounts, explode, labels, displayNames] = parseArgs(args, nargs);]
Thank you for teaching me the right one!

I am using R2020a, so I cannot try it on R2019b. But from the output of 'which pie' and the error message, I couldn't figure out the issue. The definition of the pie function seems correct.

Hello,
MATLAB R2020a has this new feature that allows the user to specify a numeric format for the percentage labels on a pie chart. For example, you can specify the number of decimal places or significant digits to display in the label. Older versions (R19b and earlier) do not support this feature, and you will be prompted with a length-mismatch error.
Please update MATLAB to the latest version i.e. R2020a to be able to use the function "pie" in the way that you mentioned.
Additionally, these links can be useful to you -
- Documentation of pie: Latest changes to "labels" input argument that allows you to specify its numeric format
- Release Notes: All the latest updates/features to MATLAB
Hope this helps!
