[kmo]

I want to know how to make a legend for 3d graph.

I actually posted my question on the following thread but since there havent been any replies, I thought I could just post it here.

Hello,

I just modify the example I found on the previous thread. I added a few things, if you play a bit with these things you should be able to do something close to what you're talking about.. I hope.

Be inspired 😉 hope this help.

hi titou,

thanks for the additions but thats only the caption. I was looking for legend more like the one shown in the picture except that in the shown picture user enters the values but in the vi the legend I want, labview assigns colors to the input array, I just want to know what color it gives to which value.

Is that possible??

Hi kmo,

I'm sure it is possible to get a color map... but I'm affraid I could'nt get to the result you wish I think I'm not far..
Maybe somebody knows hox to get it from the variant, I am not used to use these "tools": Sory...

If you don't need a real 3D graph, it might be easier to use an intensity graph.

Hi Titou,

you wrote " I think I'm not far.."

I agree!

This example

Shows how to do the invers of what is being asked. More info and links can be found in ths thread.

Where CC and I team up to offer similar ideas.

Three notes;

1) CW colors are not RGB but are BGR.

2) There is a one to one relation between the colors and the map values.

3) Map values must be ascending order.

I will leave the rest to you!

HI Ben,

thanks for the information.

I have already checked that forum thread but in that 3d map the values for each color are assigned by the user but in my case I want to retrieve the values from the 3d plot I have. The values are assigned by labview and I want to see which values they are.

I hope I can get that somehow. I mean is there any Graph property or something for 3d surface plot frm where I can get the legend of that graph? In the above vi how can i get that colormap and colorvalue property for 3d surface plot??

(for the graph that i am talking about and for which I need legend please check the thread link i have mentioned on the top of this thread)

I created this vi a little while ago.  Is this kind of what you are looking for?

Hi kmo,

Randall has now posted another good example.

Please adapt your code using his example as a guide and re-post your code if you have trouble.
