LabVIEW // waveform chart // adding plots by property node

[steffen.mack]

Hello,

I have a problem by adding plots to a waveform chart by a property node.

The chart is working with two plots, but I am not able to add more plots by the property node "Value" (I want to add a maximum-line and a minimum-line to the chart).

The waveform chart is in one VI, the data comes from an other VI. The other VI writes the data by the property node "Value" to the waveform chart (within a loop). The reference to the waveform chart is stored in an global variable.

If I directly write to the chart-terminal in the VI, which contains the waveform chart, it works without problems. In this case I see the four plots.

But I am not able to do this in the other VI by the property node "Value".

If directly write the four plots to the chart-terminal I also can not save the reference in the global variable any more.

Please see the attached pictures.

I would be very pleased, if someone could help me.

Regards

Steffen

Does it work better if you use a single column 2D array as data?

Alternatively, make it to always have 4 cluster elements, but substitute NaN for plot you don't want to see.

Thank you for the answer, I solved the problem.
