Help with RPM graphic

Good Morning,

Can someone indicate if a gauge like the one proposed below is possible to in display creator?
If so, may I please get some pointers?

I would like the RPM to start on the bottom left and go up and turn.

I would do that by combining two different graphs. The first would be a circular bar graph for the part that turns, and I would place a horizontal bar graph for the part that continues to the right. By choosing the same colors, and using different RPM ranges, it could appears as though it was a single control.

To force the curved section into your boundaries, you would create a PNG mask (you can probably do that with Windows Paint) that would ordered (ie, placed on top of your bar graph) to obscure the parts of the circular bar graph that you didn't want to be shown.

BTW -- for an example doing something like this, use Display Creator, then click File->New - select C125 - and pick Page 9 -- that has an RPM graph that just uses a Horizontal bar, look at the "Bar Graph Segment" where there is an image that is used for the bar shape. I think you could use that for each of your bar graphs.

Also, note that that example changes the color when the RPM reaches redline (never noticed that -- very cool!)

I have actually done this (combine) for my current RPM band. I will give it a try.
We need better marking tool in DC.
