MATLAB: Autozoom in a subplot

subplot

Hello,

I have a subplot of Three plots. Whenever I zoom in the first plot, I want the second plot to zoom aswell.

So when I zoom in one thing in my first plot, I want to be able to zoom in at the same Place in the second plot.

My first two plots are two different values on the y-scale vs the same values on the x-scale.

Thank you.

you can use the linkaxes() to do just that.

ax(1) = subplot(2,2,1);
   plot(rand(1,10)*10,'Parent',ax(1));
   ax(2) = subplot(2,2,2);
   plot(rand(1,10)*100,'Parent',ax(2));
   linkaxes(ax,'x');
   % Interactively zoom and pan to see link effect

 h(1) = figure(1);
 v(1) = plot3(rand(10,1),rand(10,1),rand(10,1));
 h(2) = figure(3);
 v(2) = plot3(rand(10,1),rand(10,1),rand(10,1));
 aH = cell2mat(ancestor(v,'axes'));
 linkprop(aH,'CameraPosition');

The two plots should rotate together now.

MATLAB: Axes auto-zoom based on a given line

Hello,

I understand that you would like to be able to constrain the zoom in the y-dimension based on what data if currently in view. Probably the easiest way would be to create a callback for the zoom object that manually adjusts the y-limits based on the data. This documentation page is helpful in determining the format of the callback functions, and other zoom properties.

Here is a quick example to demonstrate how to do exactly that:

function ZoomCallbackExample
% Sample data
x = 1:100;
y = rand(size(x));
y(5) = 5;
xEvents = 10:10:90;
yMin = min(y);
yMax = max(y);
% Plot data and events
hFig = figure;
plot(x,y,'-k')
hold on
for iEvent = 1:numel(xEvents)
    plot([xEvents(iEvent) xEvents(iEvent)],[yMin yMax],'-r')
end
hold off
% Modify zoom behavior
hZoom = zoom(hFig);
hZoom.Motion = 'horizontal';        % Only allow user to zoom x-axis
hZoom.ActionPostCallback = @(obj,objEvent) afterZoom(obj,objEvent,x,y);
end
function afterZoom(~,objEvent,x,y)
% Change axes y-limits to match only what data is shown
hAx = objEvent.Axes;
yInView = y(x >= hAx.XLim(1) & x <= hAx.XLim(2));
hAx.YLim = [min(yInView) max(yInView)];
end

I hope this demonstrates the effect you are trying to achieve.
