I am sorry if this has been covered in teh archives or is RTFM-sh but I looked in both places and am low on time.  I want to use text as the value for the X-axis ticks not numbers.  Something like 'Trial1', 'Trial2', 'Control' instead of 1,2,3.  

Is this even possible? It seems that this would be a VERY common need.  I think that it must be obvious but I just can not figure it out.  I fi just try to supply the text labels as a list the same place the normal xVals would be used (pl.plot(xVals,yVals)) it does not understand.
