Hello, I was wondering if there is any way to do a horizontal
> bar chart using Matplotlib? Any responses would be greatly
> appreciated.
Not currently. Implementing matlab's 'barh' is left as an exercise to
the reader 
Kidding aside, this would be very easy to implement following the
example of 'bar' and would be a nice addition. Submissions welcome!

The matlab barh doc string
help barh
BARH Horizontal bar graph.
BARH(X,Y) draws the columns of the M-by-N matrix Y as M groups of
N horizontal bars. The vector X must be monotonically increasing
or decreasing.
BARH(Y) uses the default value of X=1:M. For vector inputs,
BARH(X,Y) or BARH(Y) draws LENGTH(Y) bars. The colors are set by
the colormap.
BARH(X,Y,WIDTH) or BARH(Y,WIDTH) specifies the width of the
bars. Values of WIDTH > 1, produce overlapped bars. The
default value is WIDTH=0.8.
BARH(...,'grouped') produces the default vertical grouped bar chart.
BARH(...,'stacked') produces a vertical stacked bar chart.
BARH(...,LINESPEC) uses the line color specified (one of 'rgbymckw').
H = BARH(...) returns a vector of patch handles.
Use SHADING FACETED to put edges on the bars. Use SHADING FLAT to
turn them off.
Examples: subplot(3,1,1), barh(rand(10,5),'stacked'), colormap(cool)
subplot(3,1,2), barh(0:.25:1,rand(5),1)
subplot(3,1,3), barh(rand(2,3),.75,'grouped')
