Remove a zero array

Recommended Posts


I am aquiring data from 8 channels (4 devices) so in order to plot them I added a build array (see attached picture) and created a 2d array. If one or more devices are switched off or disconnected this will create an array full of zeros (column H).

How can I avoid this?

Don't turn the device off? You should describe what your ideal outcome is. What you probably should do is conditionally disable plots on your graph.

Thank you all for your replies,

Ton's idea works but I notice a "display delay" when the waveform array data appear on the chart. When the 2d array is connected to the chart the data appear to move faster.

Darren's article is very interesting, how do I plot an array of clasturs of arrays into a chart?

Antoine's idea creates zero columns like 1 & 2 where as I would like to create columns like 3 & 4:
