Hi,

I have a barh plot. Suppose it is generated by:

c = categorical({'apples','pears','oranges'});
prices = [1.23 0.99 2.3];
barh(c,prices)

and the resultant plot is

Thus, I want to add the bottom axis on the top. I have tried the following code, but without obtains the desired result:

ax = gca; % current axes
ax_pos = ax.Position; % position of first axes
ax2 = axes('Position',ax_pos,...
'XAxisLocation','top',...
'Color','none');

And the result is:

As you can see, in the left bar appears the numerical indexes. Do you have a solution?

The axes function creates a new axes rather than changing location of previous one.

To change the location of x axes only, you can try:

ax = gca; % current axes 
ax.XAxisLocation='top'; % change location for the created axes
