VIYA Pie chart radius lock

[GuyDyson]

I am producing a report in Viya that requires side by side pie charts. My problem is that the pie charts dynamically resize, not just based on screen real estate, but also due to the selected data. Quite often one is smaller than the other and the relative sizes swicth as different data is selected. What I would like is to have both charts the same radius.

I have found that when the label location is set to "outside" they resize depending on the data, so I am getting the two charts changing size when different data is selected. If I set the label location to automatic, they seem to stay the same radius.

Can there be a way of:

a) locking in a minimum and maximum radius for pie/doughnut charts or

b) setting the dimensions to match an adjacent object.

Sorry, I meant to include this image as well showing the different sizes to previous
