Enhancement for Meter

[Ortelius]

This is an enhancement request for the Meter component.

Would it be possible to implement some kind of color grading in the meter component similar to the attached picture where the colors and boundaries are arbitrary?

Actually, this is already possible with the DialIntervalMarker:

Let me know if you have further questions.

PS. The documentation on gauges will be improved soon.

Thank you, I'll have a closer look at this, but it seems like you got it all covered.

Would it be possible to make the colors gradient and faid into each other? I've been doing some tests with the DialConicalPaint, but it doesnt really fit my needs. The problems I get is that I cant set a start and end point for each color, and I cant specify how "sharp" the fading should be.

What I'm trying to describe is something like this:

Here I've used the DialConicalPaint with the angles 180,90,0. However this isn't nearly as informative as the example we started this thread with, what I'm looking for is some kind of trade-of where I get the nice color gradings and still keeps the information.

Thank you.

I think the best approach might still be to use the DialIntervalMarker as in my previous example, but to change the Paint used to fill the segments to be a DialConicalPaint. I'll have a go and see what happens...

How about this...?

Gauge With Color Grading

If you look at the code the work is all done in the addMarker method. The idea is that if you want, say, the yellow region to start at a value of 60 then you start the transition sometime before that. The method allows you to specify how quick the transition should be. A key idea with this approach is that the colors are linked to axis values and the corresponding angles are calculated, which means that if someone later comes along and changes the presentation of the dial the color settings still work.
