Waveform Nextion (Add-function)

Hey friends.

Maybe someone of you knows this.

I am using the Waveform on my Nextion to plot data.

To write datapoints to your Waveform, u can use:

    String str = String("add 3,0,")+String(temp);

where temp are the values u want to write.

My problem now. I dont want to plot a datapoint every pixel on the x-axis. I want more space on the x axis between the datapoints.

Someone know, if this is possible? If so, how?

Thank you very much
