drawing a guage

[netee]

Hi

I am doing a project where I should control the rotary meter, so my users require me to show the position of the rotary with a guage. so i want to know how can I show the guage with a thicker needles. I want to have two needles with a label on them( e.g needle1) and the needles should be able to rotate as the rotary meter rotate. I tried to draw it but it does not work at all.

Please help

Hi netee,

right click on your gauge (in the Front Panel) and select "add needle".

see the attached example.

Thanks for the example. I did show them the similar picture but they say they want a picture with thicker needles. The needle should  even be thicker at the tip of the needle and be able to number those needles so that they can clearly know which needle is in what position.

Thanks!

Hi netee,

you can change the color of the needles.

Thanks! the problem is there are the rotaries which have got to be represnted with six needles so it is going to end up being confusing for using six different colours. Is there another alternative?

Hi netee,

you can use something like this, or one gauge for every needle.

Thank you. The example is gonna help but I want to know if there is a way of defining the shape of my needle(e.g the thickeness or structure) because the users want something that can duplicate the system they have.

Thanks!

You can replace the needle with an arrow from the decorations palette (see tst's Nugget on customize guages).

Otherwise you can use the Picture Control to render the needle as required.

I don't think it's possible to make the needles thicker. I've even tried to customize the gauge. In customize you can select a needle then import a picture from file (say, an image of a "fat" needle) but the image just orbits around the axis. It looks pretty stupid. Customizing controls in LV is still very rudimentary at best and a waste of time.

This is just to illustrate that tst's technique of using the decorations to replace the needle does rotate.

But I agree with Paul that if this technique is not good enough, rendering the needle in a picture control is the only option.
