Hi Stely,

i can't see anything from your post. If you want to show images, then you have to attach them to your post, we can't see them if they are on your harddisk. Can you please explain where you have problems?

You can read the chart history. You receive an array of cluster elements. There you can select which channel you need. You can use a for loop and an unbundle function. If you have your selected channels, you can write the data to your graph. There you can change the color for each plot using a property node.

Hi Stel,

the attached example shows how you can get only a single plot from the history. It's also possible with waveforms.

Hope it helps.

Hi Mike,

I followed (I hope so ) your advice and example. Yours example works perfect, but when I use 

the signals from DAQ I get displayied all the signals in the right color, but with lots of samples missing in between

Thank you!

Stel

Pls see the attached .doc file with captured images
