[Matplotlib-users] Noob Q's: Filling, and centring bars in a bar chart, centring xticks and positioning text against a log y axis

[Tristan S. <tri...@gm...>]

Hi all,

I'm just getting started with matplotlib and am having a few problems
producing a simple bar graph. The code I'm writing to produce this can be
found here: http://pastebin.com/T0WA2dh8

The issues I'm having are as follows:

- The bars in my graph do not show as filled blue after I make the the y
axis logarithmic. How do I stop this from occurring.

- Each bar needs "centring" - they are arranged to the left of where I'd
like them to be currently.

- I'd like each of the ticks on the x axis centred beneath each of the bars.

- I'm struggling to position text neatly above each of the bars -
I've managed to position text well horizontally but not vertically. The log
scale is making it hard for me to work out where to position them.

- I'd like numbers in normal integer form not 10 to power form on the y
axis.

Also how do I label each axis?

Any help offered will be very much appreciated.

Cheers,
Tristan
