How to design a front panel vector indicator (display)

[aeastet]

Here is a version for 8.5. I will have to figure out how to change the needle size for wind speed.

Ah, OK thanks. I was wondering if you had a cunning way of changing the needle size.

I guess careful use of the height and width proerty nodes might work, but that sounds like a bit of a nightmare!

This VI might get us going, I am busting my head trying to calibrate the circle and the needed.

I need help

It is saved in previous 8.5 version

Hmmm, you would have to come up with a way to put increments on the picture to calibrate the circle.

I still think that using an existing graph from LabVIEW would be easier. Have a look at the attached where I've compared a polar graph with an xy graph. Both can easily be made to look more elaborate, this is just a quick example.

They do the same thing, but I think my preference lies with the XY just because of the sheer range of options for customising.

Thanks very much, I will play around with all the options.

Just a thought... if you want to stick with the code that you posted above, one way to calibrate the circle is to add the colour ramp to the windspeed and add matching circles to your picture.

See the attached (I took the liberty of tidying it up a little so I could see what was going on, and also removed the mathscript node)

Plenty of options to choose from - Enjoy!

Thanks Ian, You have been very helpful

Thanks everyone. I would work on all the options

Hi folks.

Many nice tries doing the wind vector. Please note that wind vectors are degrees clockwise from North.

I have attached a zip of a (modified) version (of a previous try) that now works.

Also, I back-ported to LV 8.5.

Enjoy.
