Fix bad 'g' argument for drawHighlightPointCallback.

[dygraphs.git] / docs / ssi_server.py

#!/usr/bin/python
'''
Use this in the same way as Python's SimpleHTTPServer:

  ./ssi_server.py [port]

The only difference is that, for files ending in '.html', ssi_server will
inline SSI (Server Side Includes) of the form:

  <!-- #include virtual="fragment.html" -->

Run ./ssi_server.py in this directory and visit localhost:8000 for an exmaple.
