Issue with a chart... when i create a radar chart with only one expression, it works just fine... but when I add another expression for comparison, it turns out like this:
It looks like it only makes it smaller, because it needs space for the legend.
To solve this you can just turn of the legend (Properties >> Presention : Show Legend)
or
Adjust the size or location of the chart parts by holding SHIFT+CTRL. This will make a red border apear around the different parts of the charts, and makes you able to adjust them.
