MATLAB: Set same xlim for all subplots

gcalabel;set(gca)subplotxlim

Hi all,

i need to specify one "xlim" for my all multiple subplots. I read already answers here but i got some problems about my labels. It disappear. I think; because of "set(gca)" on my codes. I couldn't figure out, how to solve this. If you any idea i really appreciated that. Here my codes of a subplot. Thank you so much!

You may want to use linkaxes on your subplot axes.

MATLAB: How to add tick just for the left axis

Here are two methods to show ticks only on the left axis.

Use yyaxis

This method creates a 2nd y axis on the right that is independently customizable and not used (unless you want to use it).

ax = axes(); 
box(ax, 'on')  % default

% Set axis tick length and direction
ax.XAxis.TickLength = [0 0];
ax.YAxis.TickDirection = 'both';
% Create 2nd y-axis on right and set y axes colors
% to match the x-axis color
yyaxis right
ax2 = gca(); 
ax.YAxis(1).Color = ax.XAxis.Color; 
ax.YAxis(2).Color = ax.XAxis.Color; 
% Remove ticks on right axis
ax.YAxis(2).TickValues = []; 
% Return control back to the left axes
yyaxis left

See image below for results.

Use xline and yline at axis limits

ax = axes(); 
box(ax, 'off')  % default
ax.XAxis.TickLength = [0 0];

If you want the y-ticks to be in both directions,

ax.YAxis.TickDirection = 'both';

If you want the right and upper axes lines but without ticks, you can make is appear as though 'box' is 'on' by setting the axis limits and adding a xline and yline.

% This syntax just sets the axis limits to their current value
xlim(ax, xlim(ax))
ylim(ax, ylim(ax))
% Set right and upper axis lines to same color as axes
xline(max(xlim(ax)), 'k-', 'Color', ax.XAxis.Color)
yline(max(ylim(ax)), 'k-', 'Color', ax.YAxis.Color)

If the axis limits change after this change, the pseudo-box lines will no longer be positioned correctly so this should happen after all other plotting and positioning is done on the axes. The first method is therefore safer.

Final result for both methods

MATLAB: Problem with tick marks on second y-axis

...the following command ... doesnt work. Whats my problem?

set(AX(2),gca,'YTickLabel',[0,5,10,15,20])

Got too many handles -- you told it to work on AX(2), the RH axes already, so don't want (and can't have) the gca as well--

set(AX(2),'YTickLabel',[0:20])

Actually, you really probably want to set the tick values, not just the labels. The 'ticklabel' property writes the text on existing tick marks wherever they're located and in whatever number they already exist, either wrapping the text over if fewer text entries than ticks just ignoring extra entries if more strings than the number of ticks are passed. That is, for this purpose use

set(AX(2),'YTick',[0:20])

instead and the labels will automagically reflect the tick location values and be at the locations wanted consistent with the axis limits. The label property is really user-changeable to allow you to use other labels besides the defaults like categories or the like. One other use is to fixup the sloppy formatting in the default wherein the '0' and '1' in the default axes tick marks lack the '.0' to be consistent with the intermediary '0.1', etc. It's just a little detail that makes Matlab plots look less professional than they should... :(

Oh, one last thing...on plotyy, I generally just use

set(AX(2),'xtick',[])

to just not display the second x-axis labels at all. One still must do any scaling on both, of course, but saves just a little on the formatting, too.

ADDENDUM

I've not used the recent release of Matlab "in anger" having retired from the technical consulting gig to return to family farm in roughly 2000. At that time linkprop wasn't available in R12 but the alternate way to keep the two x-axes in synch with plotyy appears to be (after just a very brief test) to be

hAx=plotyy(...  % create the handles/basic figure
hLnk=linkprop(hAx,{'xtick','xticklabel','xlim'});  % link the x-axes

Now you can just use whatever operations on the one axes object and the two will stay in synch...

datetick(hAx(1),'x','keeplimits','keepticks')

and both change together. It's kinda' handy as datetick hasn't been vectorized to accept multiple handles for some reason I don't quite follow.
