stairs function not working

stairs function not working. Empty figure. Any idea

[Adam]

Since you posted no code then no! The stairs function works fine if you give it the right inputs and have your axes setup appropriately.

Thanks Adam. It does not work with the simple code and i tried this simple example directly copied from Matlab. although it does work when i run it in browser. so dont know what could be the problem.

X = linspace(0,4*pi,40);
Y = sin(X);
figure
stairs(Y)

[Adam]

Works fine for me so long as I add a ';' after 'figure'.

What does which stairs give?

[Jameel Qadri]

Thanks KSSV. it gives empty figure no display of the graph.

[Jameel Qadri]

Tried ; nothing showing up.

which stairs

is a command at the command line to prove you've got the correct stairs m-file in the path being executed, not a question about what you were seeing. What response did you get; it should be something like

>> which stairs
C:\ML_R2014b\toolbox\matlab\specgraph\stairs.m
>>

with a specific path/version system-dependent, of course.

You can also try

clear stairs

and then try the example again to just clear any inadvertent variable you may have aliased the function with which is the solution to the which command showing you have done something of the sort.

Thanks dpb. The mistake i had done was i had given the file name as stairs.m. I changed it, now it works.
