Re: How to create "Parallel Coordinates" chart

Hi Yeray,

Thank you very much for your supports. I want to display information for a series which has many attributes (more 2) and each attributes place on each Y-Axis. I think custom axes can't solve it because each series only belong to 1 custom axes.
