How Can I use TDMS Icon to save a WaveForm Chart?

[vanny]

I have a Waveform Chart in which there are 3 function showed.

Now I desire to save data with TDMS Icon.

To Waveform Chart arrive a Cluster of Real Number, but when i can't connect a cable: see the picture.

How can i solve this problem?

You cannot use the local variable of the chart to save anything. You would need to use the History property to save the current data and the TDMS Write will not accept that data type either. You could convert the history data to a 1D waveform data type.

Thanks Dannis. Are U sure that I cannot use the local variable of the chart to save anything?

I think that it's possible... 😉

I should have been clearer. You cannot use the local variable to save anything except the very last value for each plot. So, in order to save everything, you would have to do a file write each time the chart is updated.
