While reading the first part of your post I was thinking of a categorical chart. And then -- you are already on it. Indeed, this is the recommended approach in this case due to the different length of the months. We have not planned any updates on the DateTime management in RadChart as we believe it is capable of handling most of the cases (well, indeed, using categories if needed). As for RadChartView -- even still in beta, I would encourage you to give it a try. I am sure you will be satisfied by the product quality.
Just a side note on the categorical RadChart -- you can remove the property with the string representation of the month. AxisX exposes a property -- DefaultLabelFormat
for cases like this. So, set IsDateTime
and provide the desired format in DefaultLabelFormat.
