How to align the two axes in one figure

I have a problem with aligning two axes in one figure. the two y axes are well aligned while the fig window is maxmized, but not in correct position if the fig window is not maximized.

How are you creating the plot?

 Firstly,

 bar(ItemAxes1, 0:1:(LimitRight+1),  [data1_Mean' data2_Mean'], 'BarWidth',1.0);

Then,

 plot(ItemAxes2, 0:1:(LimitRight+1), [data1_Frequency' data2_Frequency'], 'Marker','s');

Would someone give me some clue about what happened? I could not draw with plotyy because of the bar graph.

[Walter Roberson]

plotyy accepts function handles of the drawing routines, so you can use it for bar graphs.

Hi Feng,

Could you try the following code snippet that uses "plotyy" to draw both a bar graph and a line plot in the same figure? Are the axes aligned in this case or do you observe the same behavior?

clear all;
clf;
xlabel = [1 2 3 4 5 6 7]';
y1=[1 2 3 4 5 6 7]';
y2=[0 1 2 3 4 5 6]';
[haxes, hline1, hline2]=plotyy(xlabel, [y1 y2], xlabel, [-y1 -y2], @plot, @bar);

Regards,

Vidya

That aligns for me in R2014a on OS-X. If you are using R2014b or newer then you might get something different than I do.

In addition to plotyy as mentioned in the comments, I sometimes use (in R2015a) the following command to add a listener to my top axis that edits the position of my bottom axis to match. For handles ax1 below and ax2 on top:

addlistener(ax2,'MarkedClean',@(varargin)set(ax1,'Position',get(ax2,'Position')));

(This assumes that both axes use the same units for position.)

This is excellent. I have found no other way to sync up two y-axes that are on the same side for two different x-axes. Your line of code plus making the ylim's the same was key. Thanks, Robert.
