Clear XY Graph

[Nextal]

Hi,

I would like to ask if there is any property node to clear the data of a XY graph build using "Build XY Graph" without using the Reset input. I tried to clear it with

but it does not work. Thanks!!!

Writing empty x and y arrays does in fact work. You have to attach your actual program if you want any help.

Hi Dennis,

It does clear however when I run my program again I can still see the old data.

Then your original question does not make any sense since it actually does work for you. Finding a property that you can write to would not make any difference if your program structure is flawed.

Sorry, I cannot see anything in that bottom image.

Hi Dennis,

Sorry maybe I am not explaining my problem really clear. Wiring the emply array clear all the point on my graph, however when I start auto mode again the deleted data appear again and my new graph overlap the previous graph. 

Is it possible for you to view the bottom image by right click->view image?

Are you using the normal XY graph or the Express? I don't think I've ever used the Express but I think there are shift registers in it that you would need to clear in the Build XY Graph function. If not, I would look at your other shift registers and see if you need to clear them.

Hi Dennis,

I am using express.

[Dennis_Knutson]

You probably have to use the Reset to clear the internal data. You can look at the block diagram of the express VI. As I said, I don't use the express VI.

Thanks Dennis for your help.

I guess I will just use the normal XY graph and wire it to empty array to reset it 🙂

The normal xy graph does not store any internal data.
