Folks
I have couple of question regards itools hear is my question:
I want to import an array to iplot and after smoothing the data I want
to export that data to idl(the last smoothed data)and also I want
digitize couple of data in iplot (means get an array (2 dimensional)in
idl). in iplot it shows the x,y coordinates but I want to save those
to an array. for example let my data is like this:
X=findgen(100)
Y=x+10*randomu(s,100,100)
I call :
Iplot,x,y
And filter->smooth…. I want to take the last smooth x&y coordinate in
IDl after that digitize some point on the curve and also export that
to idl.
Any help will be appreciated.
Dave

no digitize means extracting sevral (x,y) form a plot. i know this:
cursor,xi,yi,/normal
but how we can take it in Iplot.
