Plot lines that end with a square bracket

My goal: plot a horizontal line with a square bracket (---]) end to it.

I usually plot horizontal lines with 

line([0,1],[2,2],'linestyle',':')

I can add usual markers at the end by 

plot([0,1],[2,2],'o')

but not square bracket.

Any suggestions?

Solution

  • Here's a terrible hack that kinda achieves what you want:

    XVALS = [0,1; 0,2; 0,3].';
YVALS = [3 3; 2,2; 1,1].';
INVIZ_OFFSET = 0.04;
figure(); 
% Step 1: Plot squares:
plot(XVALS(2,:), YVALS(2,:),'bs');
% Step 2: Plot invisible squares:
hold on;
plot(XVALS(2,:)-INVIZ_OFFSET, YVALS(2,:),'ws','MarkerFaceColor','w');
% Step 3: Plot lines
plot(XVALS, YVALS,':b');

% Play with limits:
axis image; xlim([0,5]); ylim([0,4]);

    Result:

    The idea is that a "bracket" marker can be obtained using an obscured square marker. Obviously this isn't suitable for all plots, but I think you can work from here...
