Dear @thowrabbit ,

Thanks for reaching out to the forum!

Have you tried giving a look at our tutorials? For example this one. I also suggest you take a look at other similar questions on the forum as this is a very common topic.

Cheers,
Vincenzo

Can you provide a plot showing what you want to achieve ?
