Hi all,

I would like to link all the x axes but only a subgroup of the y axes in a figure. For example is I have 3 axes (ax(1:3)), I want all the panels to show the same x domain but only the first 2 to rescale the y axis in a similar way.

If I try this:

linkaxes(ax, 'x');
linkaxes(ax(1:2), 'y');

the second linkaxes cancels the first one, so I end up with only 2 panels linked.

Is this type of link possible?

Thanks,

Razvan

EDIT:

Here is an example to make the question more clear:

x = 1:1000;
figure
ax(1) = subplot(311);
plot(x .* sin(x));
xlim([51 100])
ax(2) = subplot(312);
plot(3 .* x .* sin(x));
xlim([51 100])
ax(3) = subplot(313);
plot(sin(x));
xlim([51 100])
linkaxes(ax, 'x');
pan xon
% linkprop(ax(1:2), 'Ylim');

If I pan the lower panel the upper panels rescale and look nice. If I uncomment the linkprop line then the top panels are "y-axis linked" but they don't rescale anymore when I pan the lower panel. (Note: the panel that you use to pan doesn't rescale in any case)

So the question is: How can I use linkprop to link the ax(1:2) y axes but to keep them rescalling while I pan along x (in other words to keep 'ylimmode' 'auto')?

在 MATLAB Online 中打开

MyScript.m

%%Initial Data
x = 1:1000;
y1=x.*sin(x);
y2=3*x.*sin(x);
y3=sin(x);
rangeX=[51 100];
%%Plot Figure
h.fig = figure;
h.ax(1) = subplot(3,1,1);
plot(y1,'Parent',h.ax(1));
h.ax(2) = subplot(3,1,2);
plot(y2,'Parent',h.ax(2));
h.ax(3) = subplot(3,1,3);
plot(y3,'Parent',h.ax(3));
h.link(1) = linkprop(h.ax,'XLim');
h.link(2) = linkprop([h.ax(1) h.ax(2)],'YLim');
xlim(rangeX);
%%Pan Handle
h.pan = pan;
guidata(h.fig,h.ax);
setAllowAxesPan(h.pan,h.ax(1),false);
setAxesPanMotion(h.pan,h.ax(2),'horizontal');
setAllowAxesPan(h.pan,h.ax(3),false);
set(h.pan,'ActionPostCallback',@mypostcallback);
set(h.pan,'Enable','on');

mypostcallback.m

function mypostcallback(obj,evd)
% Extract Data 
h_ax = guidata(obj);
y2 = get(findobj(h_ax(2),'Type','Line'),'Ydata');
% Get Range
rangeX = round(get(evd.Axes,'XLim'));
rangeY = [min(y2(rangeX(1):rangeX(2))) max(y2(rangeX(1):rangeX(2)))];
set(h_ax(2),'Ylim',rangeY);

Doesn't work...

Pan to x ~ 500 and you'll see that the middle axes don't rescale properly...

Thanks for your effort though. Any other suggestions? Anyone?

Try with linkprop() and link XLim and YLim as needed

Great! Thanks! One more thing... Before I link the ylim properties the y axes rescale such that all the plots look nice, when I pan along the x axis. After linking them I think all the axes take the ylim property of the first object, so the other plots can look ugly if the plots extend outside the y domain of the first plot. Can I keep this autorescalling property for the y axis but to rescale all the plots in a similar way?

I think I should do something like

set(ax(1), 'ylimmode', 'auto')

but it doesn't seem to work after I link the axes...
