Trouble displaying uicontrol text when it's a decimal

Hello,

I'm trying to display a title for a table I'm making, but I can't seem to get it to display numbers.

Here is the part of my code:

prompt={'Enter the mach number (from 1 to 5 by intervals of 0.2):'};
title='Message'; 
answer=inputdlg(prompt,title, [1 30]);
M=answer{1};
MachNumber=str2num(answer{1});

f = figure('Position',[350 -100 700 930]);
m=sprintf('Mach %.1f', MachNumber);

txt = uicontrol('Style','text','FontSize', 20, 'FontWeight',...         %creates title
    'bold', 'Position',[110 865 110 28],'String', m);                   %creates title

When I run it, it will only display "Mach" but not the following number. What I found interesting was that in the command window m shows up correctly, just not in the GUI panel.

>> m
m =
Mach 1.2

How can I fix this? I also want to keep the 1 decimal number format (1.0, 1.2, 1.4, etc.)

Thank you!

When I run your code, the number doesn't show up. This is because your uicontrol() textbox isn't wide enough. I change the 'position' property to [110 865 160 28] and it shows up as 'Mach 1.2' for me.

Oops, overlooked that. Thanks!
