29 May 2012 Polar 2 An update to Matlabs built-in polar.m Author: Daniel Armyr

If there /is/ to be an updated version of polar2.m at any point, it would be fantastic if it could also give the user control over the number and or spacing of the rho-axis gridlines... something akin to the 'ytick' parameter in cartesian axes. Thanks again!

Wow -thanks Daniel, I look forward to any updates that may be available!

Daniel - Thanks for filling the polar plot gap for those of us who work with dB attenuation. I've been using your older 'pp.m' for several years now. Despite it's girth and bugginess, I've come to love the control it grants over the graphical aspects of the plot, such as 'ThetaStartAngle' and 'ThetaDirection'.

I'm working on creating a GUI with a polar plot in it. Reading through the comments on the 'pp' page, I gather that we can't use pp to plot into existing axes (or subplots, for that matter), hence 'polar2.'

So, now I can plot my polar into the axes of my choice - Great! But, I seem to lose control over the orientation of the polar coordinate system and the theta direction. Is there a way to set 0 degrees at the top of the plot and plot clockwise?

Additionally, it appears that rho values that are more negative than the 'CenterValue' aren't truncated, as with pp.m. Instead, they appear to be plotted 'through' the center of the plot, 180 degrees off. in pseudo-code,

if rho < CenterValue
plot( (theta - pi), (CenterValue - rho) )

Is this a fundamental limitation in polar2, or is there a workaround (other than setting CenterValue < min(rho) )?

Thanks!
