DPlot

Thanks for explaining. So I can simply delete the X and Y values for positions where I have no values for magnitude and direction. That's what I'll do.

I did also find that if I delete just the magnitude and direction, and use a comma delimited csv format, no vectors are shown for positions where ...

Thanks for your prompt reply.

I understand that for a vector plot, DPlot needs a grid of positions (positions given by X and Y values) where the vectors are to be displayed. Then for each X,Y position, DPlot also needs a value for the vector magnitude and a value for the the vector direction (angle ...

I am creating vector plots and several other types of plots of experimental data. I have data that is not complete, there are missing data points because of the experimental technique. For example, I am plotting velocity vectors on a 75x25 grid, but I do not have data (or the data point is zero) for ...
