MATLAB: Zoom and polar axes

2017aaxesMATLABpolarpolarplotzoom

__Hi guys. I have MATLAB 2017a and I've faced the problem, that zoom doesn't work with polar axes. I've met another one question with the same problem in R2016B version of MATLAB.

__1. Is there any way use ZOOM with polar axes?

__2. Does it work well in newer versions of MATLAB?

The zoom() feauture seems to be disabled on polaraxes.

You could use set rlim() and thetalim() to zoom into a specific area.

The Antenna Toolbox offers a polarpattern class that does allow for zooming and other interactions but it doesn't technically use a polaraxes.

MATLAB: Polar Plot with a moving marker

Not entirely sure what you mean by move around the circle but here is an example:

function clicktest()
theta = 0:0.01:2*pi;
rho = sin(2*theta).*cos(2*theta);
figure
ax(1) = polar(theta,rho,'--r');
hold on
ax(2) = polar(NaN,NaN,'g*');
set (gcf, 'WindowButtonMotionFcn', {@mouseMove,ax});
function mouseMove(object, eventdata,ax)
C = get (gca, 'CurrentPoint');
[theta rho] = cart2pol(C(1,1), C(1,2));
title(gca, ['(angle,factor) = (', num2str(theta*180/pi), ', ',num2str(rho), ')']);
markerspot = sin(2*theta).*cos(2*theta);
[x y]=pol2cart(theta,markerspot);
set(ax(2),'xData',x,'yData',y,'markersize',20);

MATLAB: How to create PolarAxes with GUIDE

Sorry, polaraxes were added after GUIDE last had a feature update.

You can have your GUIDE code call polaraxes() parented against the appropriate container, and you can put the resulting handle into the handles structure. Or if you put it in the CreateFcn callback for the appropriate container then as long as you gave it a tag, GUIDE would notice the object and put it into handles automatically.
