LineSeries for complex datas

Hi,

many data series do have complex values, means they are determined by common x-values and two y-properties:
Magnitude and Phase or Real- and Imaginary-part.

For now you have to use two independend series, one for magnitude and one for the phase.
One series assigned to the left axis and one to the right axis.

It would be great to have a new LineSeriesTyp for complex datas with x-values, y-values and y2-values and the according properties.
So f.e. it would be possible to hide magnitude and phase simultaneously by hiding the series instead of hiding two series one after the other.

Best regards

Hi Heinz,

I'm not sure to understand how are you representing the complex numbers right now. To draw vectors you could use the Arrow series.

Could you please send us a simple example project we can run as-is to reproduce the situation here?

Thanks in advance.

Hi Yeray,

I attached two pictures to show what the intention is.
The same result can be achieved by using two independend lineseries for amplitude and phase. But having many pairs of complex datas or mixed datas ("normal" data = 1 series / complex = 2 series) you have always to know which two series belong together whatever the user will do ( f.e. changing the order of the two series would falsify an operation because amplitude and phase would be interchanged).

Best regards

Hi Heinz,

Thanks for your feedback. I'll add your request to the wish-list to be considered for inclusion in future releases.
