Better data tip for Polar graph

Is there any way to make Matlab give polar coordinates when placing a data tip on a graph instead of Cartesian?

And really, why on earth does Matlab not do that in the first place?

Answer 1

[Oleg Komarov]

At the end of the documentation of datacursormode you will find example on how to customze the text of the tip.

Answer 2

[George Sterling]

% This function changes data tips from cartessian to polar coords

function polar_datacursormode

dcm_obj = datacursormode(gcf); set(dcm_obj,'UpdateFcn',@myupdatefcn)

function txt = myupdatefcn(empt,event_obj) % Customizes text of data tips

pos = get(event_obj,'Position');

R = sqrt(pos(1)^2 + pos(2)^2);

Theta = atand(pos(2)/pos(1));

if Theta < 0 Theta = Theta + 360; end

txt = {['R: ' num2str®], ... ['Theta: ' num2str(Theta)]};

The new polarplot function in R2016a does this for you.
