I have a couple of questions about scatterpolar;
Is there a way to disable the drawing of axis ticks? I can disable the line and the labels with showline and showticklabels, but the ticks themselves are still drawn as small vertical stripes on each radial tick, and “sticking out” of the plot for each angular tick. I want to show the radials - I just don’t need to show the ticks. I could set tickcolor to white, but then the gap will be visible. And setting visible to false just hides everything which is not what I want either.
Is there a way to connect the start & endpoint of the plot automatically without duplicating the first values?
