Webalizer - generating a larger graph image for monthly stats

For visualizing the web traffic, I am using webalizer for many years. With the software being updated recently, it now keeps statistics for longer then 12 month's, provides a neat flag icon for the country stats and has the GeoIP integration. What I was still missing however was the ability to re-size the graph images. To have a bigger usage.png image, I re-calculated the parameters in graphs.c and updated output.c. The main graph showing the monthly stats (usage.png) is now displayed in 640x256 instead of 512x256 pixels. The additional 128 pixels allow to show 18 month data bars together with the 3-character month description on the X-Axis. If you are interested, the patch is as simple as dropping the updated graphs.c and output.c into the webalizer-2.21-02 source directory before doing the ./configure and make. Just click on the link below to get the updated source code files: If you set "GraphMonths 18" in webalizer.conf, the image will now be like this:
webalizer usage.png in 640x256
If you would like to see how webalizer looks for me now, my stats are openly visible here.
