#8 Bug in PlotItems._TempFileItem (affects Win32)

PlotItems._TempFileItem.init sets filename instead of self.filename, so del fails, and graph sometime doesn't get drawn under Windows.

Also, remove below comment, since prefer_inline_data=1 doesn't work on windows when gnuplot is used to draw more than one graph (apparently randomly, some graphs don't get drawn when the info is piped).

Apparently gnuplot on windows can use inline data, but we use

non-inline data (i.e., temporary files) by default for no

special reason:

prefer_inline_data = 0

Sorry didn't see the apply(_FileItem.init, (self, self.filename,), keyw) line

Will try again to find out why only alternate graphs draw

I finally got it to work by removing the os.unlink(self.filename) line. It leaves some tmpfiles behind, but at least gnuplot doesn't barf from them getting deleted too soon.

Please read Q1 in the FAQ and see if it answers your question about temporary files being deleted too soon.

Hmmm...

Since prefer_inline_data=1 doesn't work properly with pgnuplot.exe, only available option there is to use time.sleep. Watching for output file creation shouldn't work since it's only written to later.

I got gnuplot-py to work under cygwin, which has FIFO's - so you could recommend that as well in the FAQ. However I need gnuplot-py under Win32 since I'm using scipy for some things and there isn't pre-compiled scipy for cygwin.
