RPM Meter

[karthik]

Hello,

Can anybody please tell me how to customize a meter to get a RPM meter which I have attached with this post.It is a simple control which we generally see in cars or bikes to display RPM value.It starts from 0 to 30 and changes its colour depending on which slot it belongs.For example 0 to 5 it has to display green and from 20 to 30 it has to display red.Thanks in advance.

Regards,

I am afraid if you want to have a meter that looks exactly like the one in your image that you are going to have to do a lot of low level coding. Either that or buy an ActiveX control of the kind you want.

In other words, you are going to have to write code that turns on and off the individual pixels you want.

Karthik: 1. Select the "Meter" control on the panel of the attached VI. 2. Select "Customize Control..." from the Edit menu. 3. Press the button on the toolbar to change to customize mode. 4. Import your grid pattern by selecting "Import Picture to Clipboard..." from the Edit menu. 5. Select the white background on the control and paste your grid. 6. Resize as necessary and save the control.

Adding to above...

THe color ramp values and colors can be changed on the fly.

So do the customizing as outlined.

Hide the needle

Code up the ramp color changes

You are there!

I would think Property Nodes to be the magical solution here.
