The graph automatically determines the sectors based on the data you provide. By default the rose chart uses a Category Scale
for angular axis and this means that you cannot set step and minimum/maximum properties.
However, you can change the Category Scale to a Numerical Scale and set the series X and X0 properties according to your scenario (in the attached example we used an offset of ±
10). Note that in this case you have also to set the series' ArrangeByAxis
property, selecting the angular axis you want to use.
We have prepared an example based on your scenario that demonstrates the approach described above. We hope you will find the example useful.
