I am a newbie in Illustrator. I was trying to get a donut chart with rounded end hoping this was easy. My target is the following picture:
What I did was to create a circle in blue, and over it a circle in black color. Then, this second one I cut it according to a certain angle as I was looking for a certain percentage (no matter for the moment). Then, rounding the ends, it should work, but what I get is this:
As you can see, it seems as if the ends were somehow connected, so in the black circle, there is an annoying effect I wish I could remove. Why is this happening? What did I do wrong?
