Custom dual gauge or just graphics

[Pio]

Dear All,

as I'm fun of sailing, I would like to have a custom gauge like the one (bottom right) on the attached image that's from Vistual skipper simulator. It consists on a compass rose that rotetes on the boat shape (red and green lines). In addition there is the blue arrow that rotets on the boat image again to show the wind direction.

Is it possible to customize a gauge indicator replacing the needles with a couple of transparent-background images (compass and arrow)? How?

Other advices? Should I use different approaches, like create a picture and manage it?

Thanks in advance,

Pietro

You can customize a gauge and replace parts of it with images, but you can't replace all parts and the easiest thing to do is to place an image under it and color it transparent.

The main problem with what you want to do is that if you replace the needle with something other than a LabVIEW built-in vector graphic, the imported image will not rotate around its center, so essentially, to really achieve what you want, you will need to use a picture control or a combination of a picture control and a gauge.

You can see one example of a similar indicator here, but it's nowhere near the level of what you're attempting to do. Then again, I didn't actually try there.
