07 Nov 2014 Advanced Polar Plots v2 An improved version of the MATLAB function 'polar'. Author: Daniel Armyr

Sorry, but doing anything with polar plots is very complicated since they are not first-class plots, hut basically drawn up using lines and circles. As such, any modification has to be done inside the logic of the code.

But, by changing your angular data to get the plot to draw itself using the right direction for 0° and CW you can get the data in the right Place. Then you just go in to the code and remove the drawing of the lines you do not want, then you should get the results you need. The only challenge would be to get the tick labels right, but you could hack that as well.

Or? It is listed under "Required Products" now at least.

Robert: Very nice idea. Unfortunately, I do not see that it gives a speedup in any of the cases I have tried. I will therefore say that this is not an improvement and will not update. However, if you can provide me an example where you see significant speedup using the full/sparse trick, then I would be happy to look at it and see how I can get the best performance for all cases.

I disagree, but I have given you my contact information so we can take a closer look at it.

06 Nov 2014 Advanced Polar Plots v2 An improved version of the MATLAB function 'polar'. Author: Daniel Armyr Bill

Hello,

I am attempting to plot multiple series of theta (phase) and magnitude data on the same polar plot.
I have used the 'polar', 'pp', 'polar2', and 'polar2' advanced m files. Each has a different limitation. I would like to plot each series on the same polar plot, then reorient the polar plot so that 0° at top and degrees rotate CW, using the command with 'view(90°,-90°)', . Then use the 'polarticks.m' function to clean up the plot by removing radial and angular gridline except for the main 4 quadrants. so have gridlines only at every 90°. Maybe not all in this order.

Not too terribly complicated.
I thought that I just about have what I want, but have not been able to duplicate it.----- So now I cannot for the life of me contort or rearrange the coding or revise the gca or children to make this a usable tool that we can use again and again for lots of data.

Any help that you could provide would be much appreciated.
Thank you,
Bill

Very nice, the automatic binning to the pixels is very good, and all the argument parsing stuff makes it flexible. You could replace lines 139 and 152-155 with:
canvas = accumarray( [xBinIndex, yBinIndex], 1, bins);
for a bit of speed up (and it isn't reliant on acceleration).

That was exactly what I needed
