Thread Subject: Check zoom

Hi all,

I have used the following code,

zoom on
set(fig_ttest,'WindowButtonDownFcn');
C = get(gca,'CurrentPoint');
points =(1,1)
         (3,2),etc.
zoom_factor=2;
If the current point C is equal to any one of the above points
I want to set the Xlim and Ylim and also zoom(zoom_factor).

If C is not equal to any points just zoom(zoom_factor)
But here I want to check whether the zoom is on or not, to
execute zoom(zoom_factor);

Thank you

Mekala

Suppose fig is handles of your figure

fig = figure;
%% plot something
..

Create zoom object of the figure fig

h = zoom(fig);


Get the zoom status of the current axes (in fig)

zoomflg = isAllowAxesZoom(h,gca);

0: OFF mode
1: ON mode

Set new zoom status to the axes

setAllowAxesZoom(h,gca,~zoomflg);
