Jitter on radar chart

[PedroJBrito]

Hi,

I want to make use of the radar chart not to display areas but instead to display points that should be displayed around the angleLines. What I have so far is all points aligned with the angleLines. Is there any way to make those points spreading around the angleLines? I saw a jitter example that manages the x and y coordinates but since this is a radar chart and we don't have x and y, how can I achieve the same jitter effect here?

Many thanks for your help.

Hi Pedro,

There is a way, it is not the best method but an option that I need to work out the details more in depth. So it does not have tooltip option because the dots are drawn directly with the canvas API.

Hi,

thanks a lot for your help. I've actually tried an approach like yours but I also need the tooltips, is there any way to also add the tooltip programmatically?

Thanks again for your help.

I am researching how tooltip works. Since this is something I do not understand. Once I know how to get this connected I will get back to you.

By the way, I achieved a similar result as yours with a radar chart instead of a polar one which in my scenario is a better fit as I need the grid lines to display the elements according to the group they belong which is represented by the gridlines. However the elements stay displayed along the gridline.

I wasn't able to find a solution to change the x and/or y position of those elements, do you have any idea?

Tooltips also work with it. We just used the limitation of Radar chart to our advantage.
