I've created a chart that has two line series. They share the same x-axis but they each have their own y-axis, one on the left and one on the right. The left y-axis goes from 0-120 and the right y-axis goes from 0-100.
The problem I'm having is that the grid lines look all funky, since there's a horizontal grid line at each 20-interval from the left and each 10-interval from the right. I'd like to clean this up.
Can you let me know which of the following solutions are possible. I'm using Swift 4:
I would prefer to go with option 1 if possible.
Related question: Is there a way to put a border on the graph that isn't dependant on grid lines? I'd like to add a permanent border to the right side of the graph as well.
Thanks!
