I want to have a bargraph and a waveform on top of each other. Actually a series of vertical bargraphs and then a waveform on top so I can plot two different series.
Is this not possible? I'm not seeing a way to make the waveform transparent.
Thank you.

Not possible, the Nextions don't support transparency.
I don't know if the Intellegent models support transparency, they were only recently released and I don't have one to try. You could set the Nextion Editor to one of the Intellegent models and see if you can do what you want there, and if you can then buy one.
Something I didn't think of before, if you look at the Nextion instruction set you will find instructions for drawing, you might be able to construct want you want using the drawing instructions to make the waveforms and bar-graphs you want.
Thanks! I only have an "Enhanced" screen so no luck there. I did see something in my search saying the intelligent line now supports transparency.
I do see there is a "fill" command so I could draw my own bargraphs pretty easily, I'm guessing I'd have to manually draw the waveform as well though. but hey, I guess it's better than not being able to do it at all.
You can draw over things, the last thing you do appears on top of the thing before it. For example, I was not happy with the available backgrounds and grids for a waveform. To get what I wanted I used the waveform with a background image, which means the waveform is displayed over the image with no grid, then I drew the grid I wanted over the top of the waveform once the waveform was completed. The order is important; waveform first, grid (or whatever drawing you want) afterwards.
