Math channel not visible

Post by oxd »

Hello,

I added a LowPass filter. I wanted it to be shown on top of the original signal, but it wasn't visible at all. See the picture.

The aim is to display the original signal (grayed / semi-transparently) and the emphasized math signal on top of that. Well, it doesn't need to be the pink color :-)

Is it possible? Can I define an alpha channel of the signal color?

Yes, I changed the color (the pink one), but could find an alpha channel value input to set it transparent.
And the math channel is not visible since it is overpainted by the original signal from channel A.
Is it a bug?

Use the Slider on the right hand side

to adjust the intensity of the main trace. Then use the x1.0 button at the bottom left or right of the display it doesn't matter which one, Math Channel or Active Channel

and you will see two buttons, SendToBack and BringToFront, which help to define the order the traces appear on the display.
