How to draw a thermometer marker?

[rCassani]

I want to draw a marker in a thermometer indicator (see the attach). I Drew the arror of the attach with a picture editor.
How can I draw something like the arror in my VI? I'm using LabVIEW 8.2.1.

Hi Raymundo,

you can use the decorations to draw an arrow. If you want that this decoration element is part of your control use the advanced palette and customize it. Attached is an example.

If the arrow is in a static location, just get an arrow decoration from the decoration palette and place it in the desired location.

If you want to be able to set the placement of the arrow programmatically, you can use a thermometer with two sliders and customize it. Use one slider for the temperature and the second slider for the marker. You need to customize the thermometer, import an arrow decoration into the slider, and move it off to the side. Attached is a quick draft (LV 8.2.1).

Thank you  altenbach.

Your VI was a great help for me.
But, How do you do that?  Where can I find information about customize controls?

Thanks again.

Great example but I need to have a slider with a digital readout that moves as the user sets the slider position.  Any ideas?

Check out the VI in this reply and see if it gives you some direction.

That looks pretty clunky because there is no obvious way to avoid overlaps. Maybe you can use a special format, such as demonstrated in the "slide" here.

(OTOH, if you would replace it all with a picture controls and some code, you can do anything you want.)
