Yes it's possible. The caveat is that it's not quite built in to Chaco.
These two files show how it's done: chaco/tools/save_tool.py chaco/pdf_graphics_context.py
PdfPlotGraphicsContext would of course need to be replaced by a PsPlotGraphicsContext. That's the main missing piece here. There is already a PS kiva backend(kiva.ps) that can generate the postscript output.

I would like to know that is there any opportunity to save Chaco plot as
postscript. If yes how?
