Hi everyone,

If I have array as x=fltarr(1,1,50), If I want to display it at specific position I write

> window,xs=500,ys=1000
> tvscl,x,300,525

My question is how I can save x at this position in new array z, whereas when I write

> window,xs=500,ys=1000
> tvscl,z

appear at the same position (300,525)

I think you can set z = [300,525] then tvscl,x,z[0],z[1] may be achieve your goal.

If you have a array, x, of 50 numbers

x = randomn(seed,1,1,50)

and an array,z

z = fltarr(500,1000)

and you want to put the values of x in a row of z starting at (300, 525) you can write

z[300:349,525] = x

I am just guessing that this is what you might want, because your question is not very clear. ---Wayne

Of course it does. It is the z array that should be displayed.

window,xs=500,ys=1000
tvscl,z
