Rounded axis in plot

I'm wondering if there is an option to create rounded corners for the axis. I would like to incorporate rounded axis corners in my graphics.
Thank you for your assistance.

I am not aware of this being possible. You could make the axes transparent and create several other objects to create the illusion of an axes object with rounded corners.

Ran in:
Here's one terrible way:
% normalized radius of plot box corners
cornerrad = 0.1;
% we have some sort of object in the axes
% such that the object does not extend into the corners
plot(rand(1,10),rand(10,5));
% figure out rectangle position
axrange = [xlim(); ylim()];
rwidth = diff(axrange,1,2).';
% figure out rectangle curvature
cornerrad = min(cornerrad,0.5);
hax = gca;
curv = hax.PlotBoxAspectRatio([2 1])*cornerrad*2;
% create rectangle object
hfg = rectangle('position',[axrange(:,1).' rwidth],'curvature',curv,...
'facecolor','none','linewidth',0.5);
% hide the axis axles by setting the line color to white
% normally, the figure BG color is light gray, but if saved or printed, it will be white
drawnow
hax.XAxis.Axle.ColorData = im2uint8([1 1 1 1]).';
hax.YAxis.Axle.ColorData = im2uint8([1 1 1 1]).';
hax.XAxis.Axle.Layer = 'back';
hax.YAxis.Axle.Layer = 'back';
% clean up other remnants of the axes
box off
hax.Color = 'none';
% try to set up a grid
% remove the first and last yticks so that we don't have
% ticks and gridlines hanging outside the rounded corners
grid on;
yt = yticks();
yticks(yt(2:end-1))
xt = xticks();
xticks(xt(2:end-1))
This will get screwy if you try to zoom or pan, but it's a start. Note that I'm assuming that the goal is to save/print the result. I'm relying on the fact that both axes and figure background colors are white in that case. When viewed in a figure, they normally differ. Otherwise, the problem is more complicated.
