Waveforms and complex numbers

[Hans]

Hallo

I liked the new waveform type and started to convert my signal processing VIs to this format. But then I came to some VIs that were using complex numbers for some special signal processing and discoverd that the Waveform type did not support complex numbers......

Is this correct.....and will it be fixed???

Hello Hans,
yes this is correct, a Waveform Graph don't support a complex numbers.
If you in need of display a complex number you have to choose a XY
Graph.
For example, X for Re-components and Y for Im-components.

Hans,

You are correct about the data type support for the Waveform type; it's limited to double-precision, real-valued numbers in the current version of LabVIEW (see NI's KnowledgeBase, ID# 20AACLYF).

Perhaps this is a feature we can expect in a subsequent LabVIEW release...
