Overwriting graph file?

[paues]

Is there some option to the graph type command .save that ensures that graph files are overwritten? I would like the code below to yield a graph where tmp=2 and not, as the code is written now, tmp=1. Also, it would be nice to be prompted that the file already exists.

Code: Select all

close @all wfcreate a 1900 1905 series tmp=1 graph test.line tmp test.save(t=png,u=pixels,w=600,h=400,c) c:\temp\test series tmp=2 test.save(t=png,u=pixels,w=600,h=400,c,o) c:\temp\test

I'm not sure I follow. Your program only creates one graph object, then saves that graph object twice. Since the graph object has not changed, the file on disk does not change.

As the graphed series tmp change, the graph containing that series also changes. However, the saved file does not change.

But flawed or not, my code was just an example. The question remains: can I make the save command overwrite an existing file?

Well, my point was that that is exactly what the save command does. In fact, I don't believe there is a way to stop it from overwriting the file on disk.

Take this example:

Code: Select all

create u 100 series y=3 freeze(g1) y.line series x=6 freeze(g2) x.line g1.save(t=png,u=pixels,w=600,h=400,c) c:\temp\test g2.save(t=png,u=pixels,w=600,h=400,c) c:\temp\test

You'll notice that the resultant file is a graph of X, not Y.

Thank you for straightening that out.
