suggestion(s) sought to (better) plot data

To all

I am playing around with plotting a set of (Y,Z) data.

For each point I am calculating the angle: atan(Z/Y) and a magnitude

I have managed to create some plots (see attached) but none of them are very "good" because the data is "swamped" by the few high values. I had in mind some kind of polar plot

Q1: Could any make any suggestions on way(s) of improving the plots?

Q2: Is there a way of limiting the polar plot to 0-90deg?

Any suggestions welcome...

Thanks

Regards

Q1:

Zdata vs Ydata: make both axes logarithmic

MagYZNorm: make y axis logarithmic

Polar plot: make radial logarithmic.

If you do that then you will see that the data is not swamped by a few high values, but rather that it spans many orders of magnitude.

Q2:

No, other than copying the plot to some graphics software and editing it there.

Thanks for the suggestions. The log polar plot is quite good as it does show what I "knew" about the data. Most of the data should be close to 0 or 90deg

I also tried with a histogram which probably does the job too. May converting the histogram into a % could even be better
