hi,

my problem : when i used view properties on axes, the zoom doesn't work well.

with this code, if i zoom on the third axes, the size of the plot increase, but there is no zoom action

thanks for your help

function TestZoomPlot
x   = linspace(-5,5);
y   = -1 * x.^2;
ax1 = subplot(2,2,1);
hz  = zoom;
plot(x,[y ; y+1]);
title 'Axe 1';
set(ax1,'ButtonDownFcn',@click_1)
setAxesZoomMotion(hz,ax1,'horizontal');
ax3 = subplot(2,2,3);
plot(x,[y ; y+1]);
title 'Axe 3';
setAxesZoomMotion(hz,ax3,'Vertical');
set(ax3,'view',[90 90]);
ax4 = subplot(2,2,4);
plot(x,-[y ; y+1]);
title 'Axe 4';
%set(ax4,'ButtonDownFcn',@click_4)
end

Hi Boissonneau,

When you set the view of ax3 to [90 90], you are effectively looking at the plot from a top-down perspective, which can interfere with how MATLAB's zoom feature expects to manipulate the camera view and limits.

Here is a simpler adjustment to the code that maintains the use of MATLAB's built-in zoom functionality but removes the custom view setting that is causing the issue:

function TestZoomPlot
x = linspace(-5,5);
y = -1 * x.^2;
% First subplot
ax1 = subplot(2,2,1);
hz = zoom;
plot(x,[y ; y+1]);
title 'Axe 1';
set(ax1,'ButtonDownFcn',@click_1)
setAxesZoomMotion(hz,ax1,'horizontal');
% Third subplot
ax3 = subplot(2,2,3);
plot(x,[y ; y+1]);
title 'Axe 3';
setAxesZoomMotion(hz,ax3,'Vertical');
% Commented out to avoid zoom issues
% set(ax3,'view',[90 90]);
% Fourth subplot
ax4 = subplot(2,2,4);
plot(x,-[y ; y+1]);
title 'Axe 4';
end

The callback function click_1 is referenced but not fully implemented in the provided code. Ensure you have a suitable function defined to handle the click events in your application.
