Folks,
Hi,
I have some data like:
19-Apr 35.9
03-May 32.4
11-May 23.3
......
I want to plot this data as (x-y) plot as it is. I mean in x axis like: 19-Apr, 03-May, 11-May, ... and on the y axis just the number that i have. I do not want to convert them as Julian days or something else.
Any kind of help highly would be appreciated,
Cheers,
Dave

You mean like this?
xtickname=['19-Apr','03-May','11-May']
y=[35,32,23]
n=n_elements(y)
plot,indgen(n),y,xtickname=xtickname,xticks=n-1
cheers,
Greg

Hi Greg;
Just one more thing:
How could i rotate the xtickname 90 degrees? I mean in vertical orientation?
Cheers,
Dave,

Then I think you have to position the labels yourself...
xtickname=['19-Apr','03-May','11-May']
y=[35,32,23]
n=n_elements(y)
x=indgen(n)
plot,x,y,xticks=n-1,xtickname=replicate(' ',n),position=[.15,.2,.9,.9]
xyouts,x,x*0,xtickname+" ",orientation=90,alignment=1
If you want better quality graphics (but still the old way), you can try
gmw=obj_new("gmwindow")
xtickname=['19-Apr','03-May','11-May']
y=[35,32,23]
n=n_elements(y)
x=indgen(n)
gmw->plot,x,y,xticks=n-1,xtickname=replicate(' ',n),position=[.15,.2,.9,.9]
gmw->xyouts,x,x*0,xtickname+" ",orientation=90,alignment=1
required routines are here: http://hrscview.fu-berlin.de/mex4/software/idl/gmwindow/
cheers,
Greg
