I am making a program using the IDL.
I want to make a scatter plot of the square, but the scatter plot of the rectangle is output.
To make a scatter plot of the square, How do you rewrite this program?
Please tell me someone.
;Program
pro scatter1
x1 = fltarr(3600,1200)
y1 = fltarr(3600,1200)
mvk = fltarr(3600,1200)
nrt = fltarr(3600,1200)
fname1='C:\Users\yamamoto\Desktop\mvk_20140430.txt'
fname2='C:\Users\yamamoto\Desktop\nrt_20140430.txt'
openr,1,fname1
openr,2,fname2
readf,1,x1
readf,2,y1
plot,x1,y1,xrange=[0,2000],yrange=[0,2000],color='000000'XL, background='FFFFFF'XL,psym=2,title='20140430 precipitation',xtitle='mvk precipitation [mm]',ytitle='nrt precipitation [mm]'
close, /all
end

I'm not sure I understand your question, but does adding the keyword /ISOTROPIC to your plot command solve your problem?
plot,x1,y1,xrange=[0,2000],yrange=[0,2000],color='000000'XL, background='FFFFFF'XL,psym=2,title='20140430 precipitation',xtitle='mvk precipitation [mm]',ytitle='nrt precipitation [mm]', /ISOTROPIC
Cheers,
Helder

Or, in function graphics you can use the aspect_ratio keyword:
x1 = 2000*findgen(100)/100
y1 = 2000*randomu(seed,100)
p = plot(x1,y1,aspect_ratio=1, $
xrange=[0,2000],yrange=[0,2000],symbol='star',$
title='20140430 precipitation',$
xtitle='mvk precipitation [mm]',ytitle='nrt precipitation [mm]')
Cheers,
Chris
