Moving colour ramps for UI

[try]

Hi,

I'm trying to create a color ramp that moves to the continuosly changing setpoint. So, the setpoint range will be green then either side yellow and then red.

I can get two needles to show my range and a third needle my user controls, where they have to set it within the range. But I would muck rather have just one needle and they can set it to the green band.

Thanks

Hi Andrew,

I don't understand what it is you're trying to do.

Could you post your code so I can see what you've achieved so far?

Thanks

Sarah,

Thanks for the interest, here's an example of what I'm trying to do.

Please note that battery voltage and temerature is from  analogue inputs of a DAC MX card

Thanks

Hi Andrew,

you know, you can stack several controls/indicators on top of each other?

May advice would be:
1) Create your color ramp. I would use an 1d-array of colorboxes.
2) Put on top a slider indicator for your actual value. Adjust the indicator to fit the size of your color ramp. Make the indicator transparent, leaving only the needles visible.
Now you have a needle on top of a color ramp.
3) If the range of the 'good' values changes: adjust the displayed range of the slider indicator by feeding the property node 'data range'!

Hope this helps.

Sorry about coming in late...

What is wrong with the built-in color ramp?

Hi Andrew,

I had a play around with the properties of a meter and you can control the color ramp with the Scale >> Marker Values[] property. The changes I made to your code demonstrate what I think you're trying to to.

The code is described on the block diagram (hopefully it makes sense!) Just change around the values to get it to behave how you want.
