@Jeff: Thank you for the kind words.
You have now given CorePlot 7 arguments, and you can imagine that it is not good practice to add 4 more to set the padding, a few more color control etc.
I have updated my example
github which now has an option to set the padding using the technique:
CorePlot(....)
.padding(left: 10)
.padding(right: 10)
Obviously CorePlot has many more settings that you would like to expose, but I just went for the easy ones :-)
Maybe you can add that to your code example.
