I need to use a 3 way switch in labview

[Neha987]

I need to limit the 3 points (1,2,3) in a semicircle on right side with the topmost position being 3, middle position as 2 and down most position as 1. Can this be done using only properties? I am not able to do it.

Hi Neha,

where did you get that control from?

Did you create it on your own?

Do you even know what you are using in your VI?

(Btw. what's the point of this case structure? It's pure Rube-Goldberg…)

You use a picture ring control here: when you want a special behaviour then you need to implement that behaviour in code.

(I advise not to use this picture ring. What's wrong with the slider approach?)

Btw. why did you create one two more threads for the same problem? Please keep related discussions in one thread!

Use a slider control, set the range to 1…3 and set it's scale to 1 (lowest) and 3 (top):

Actually I need to use knob only for visual purpose in my project.

It is present in labview in numeric control -> dial.

So what's your problem to use a knob/dial indicator?

[Neha987]

I am attaching an image of the knob which I need. It should slide up and slide down.

Hi Neha,

what's your problem?

You just need to adjust the scale of the dial…

[Neha987]

Could you please brief what should be changed in scale? When I am changing it its coming with 120 degrees difference between the 3 buttons.

Hi neha,

move the mouse pointer over the dial scale until it changes into a symbolic scale. Then you can move the endpoints of the scale.

I guess this is described in the LabVIEW help...

I find it much easier to manipulate the dial with properties nodes than trying to find the correct pixel to hover the mouse over to get the right cursor so you can finally click the mouse only to have the mouse shift as you click and miss. It can be frustrating at times... maybe I need a better mouse. LOL

The Min and Max values can be changed either through the properties or directly on the FP.

The data type has to be changed through the properties.

Once you have the dial all set up the way you want, you can then delete the code. The dial will maintain it's properties.

Hope this helps!
