Open figure and work on that figure

Dear all,
I would like to ask it is a way to work on a saved figure. For example, add more line plots and also change the axes. I have been trying but didn't succeed.
Here is the code that I made:
figure
hold on
openfig('x.fig')
plot(A);
ax = gca;
ax.XTick = [0 0.01 0.03 0.05]
Thanks

You will notice that the call to figure is not needed, as openfig already opens a new figure window for the loaded figure.

You should use the
fig = openfig(...)
syntax too to get an explicit handle for your figure. Relying on your desired figure always being the one in focus can lead to some unexpected bugs.
Working with explicit handles is always better. Obviously in this case that is limited - I assume your figure only contains one axes, otherwise I have no idea which axes in the figure would be regarded as the current one, but if you do only have one axes:
hFig = openfig( ... );
hAxes = hFig.CurrentAxes;
will give you your explicit axes handle to work with as well as the figure handle, if required.
