Superscript minus vanishes using latex interpreter.

When adding text to a plot, why does text(0.1,0.5,'$\tilde{V}^{+}$','Interpreter','latex')

produce the + superscript sign while

text(0.1,-0.5,'$\tilde{V}^{-}$','Interpreter','latex')

does not give any - superscript.

You are creating text objects on the same position:

t1 = text(0.1,0.5,'$\tilde{V}^{+}$','Interpreter','latex');
t2 = text(0.1,0.5,'$\tilde{V}^{-}$','Interpreter','latex');

To see the second:

• delete the first

 delete(t1)

• close the figure before calling t2
• use different position for t2

[Teja Muppirala]

To illiustrate Oleg's point:

text(0.1,0.5,'$\tilde{V}^{+}$','Interpreter','latex','fontsize',200,'color','r')

text(0.1,0.5,'$\tilde{V}^{-}$','Interpreter','latex','fontsize',200,'color','g')

@Teja: complementary!

[Stian Molvik]

y coordinate for t2 is -0.5 instead of 0.5 as i wrote earlier. They do not overlap, but still I do not get superscript minus.

[Oleg Komarov]

Try to look at your axes then =)

[Stian Molvik]

It doesn't matter if I try adding only one text object or two, it doesn't make any sense to 'look at the axes'.

The V with tilde above it shows up but the minus is neglected. If I change the - to a +, the + shows up. Is anyone able to display superscript -?

[Oleg Komarov]

If you're simply calling:

t1 = text(0.1,0.5,'$\tilde{V}^{+}$','Interpreter','latex');

t2 = text(0.1,-0.5,'$\tilde{V}^{-}$','Interpreter','latex');

Then you '-' minus subscript will be positioned in x = .1 and y = -.5 but you y-axes are [0 ... whatever]

And me and Teja could see it and I bet many others.

[Teja Muppirala]

Not to doubt you, but copy and paste these 4 lines into MATLAB. Do you REALLY not see a V with a minus sign there?

clear all;

close all;

figure;

text(0.1 , 0.5,'$\tilde{V}^{-}$','Interpreter','latex','fontsize',200);

If you don't, then I have no idea.

[Teja Muppirala]

If you tried the above, and could see the giant V with the minus sign, then it's probably just a case of your axis limits being wrong. In which case, adjust them:

t1 = text(0.1,0.5,'$\tilde{V}^{+}$','Interpreter','latex');

t2 = text(0.1,-0.5,'$\tilde{V}^{-}$','Interpreter','latex');
