    Hello, Is there a way to use a *new graphics* (NG) function (such as BARPLOT) within a *direct graphics* (DG) window ? For example, BARPLOT (NG) has some useful new features such as N_BARS parameter which doesn’t have BAR_PLOT (DG), but NG are too bandwidth consuming to use IDL from a remote computer (through ssh+X11). Thanks, Guillaume

    I am afraid you can't use New Graphics in a Direct Graphics window. A possible workaround for you might be to use the BUFFER keyword when generating the NG, use the CopyWindow method to get the image and then use TVSCL to display the image using DG. An example of how this can be done is shown below: f = findgen(10) b = barplot(f,/buffer) ;use buffer to supress display img = b.CopyWindow() ;use COPYWINDOW to get data tvscl,img,/true ;display the data with TVSCL

    Another alternative might be cgBarplot, which has a number of nice features, too. http://www.idlcoyote.com/cg_tips/barp...
