Hi a newbie question. After having a look at the date examples of matplotlib, I still have some problem with this: I have data starting at a certain date/time (e.g. 30 Nov 2006 12.00 pm). I have one data for every hour starting from the 13th hour after the starting time until the 96th hour. I would like to put on the x axis the day/hour (let's say every 3 or 6 hour). Could you please help me setting me on the right way to the solution? Thanx Frank
