Okay I've learnt a bit more about this: http://img229.imageshack.us/img229/6467/scatterplot5st6.png I need to explicitly make a new figure as well as a new axis, and put the rc calls before the figure calls, rc changes only seem to take effect on figures created afterwards. Also I was stupidly using the plot function (for plotting lines) for a scatter plot, I've now discovered the scatter function. Things are pretty much how I want them now, but I still have a couple of questions: How do I get rid of the redundant ticks on the top and right edges? Is there any way to stop some of my text labels from overlapping? Why is there such a big gap between the plot itself and the axes ticks? The scatter function seems to do this, but I don't see any option to control the size of the gap. I wonder if I've done something weird like create an axes within an axes. I don't mind the gap much, it's just surprising, and could do with being much smaller to make the figure easier to read. Here's my new source code: rc('xtick.major',size=8) rc('xtick',direction='out') rc('ytick.major',size=8) rc('ytick',direction='out') fig = figure(facecolor='white' ) axes(frameon=False) title('Comparison of lower and upperbounds per function in week one and week two') l = scatter(functions.lowerboundsweek1,functions.lowerboundsweek2,marker='s',color='g') u = scatter(functions.upperboundsweek1,functions.upperboundsweek2,marker='^',color='b') legend((l,u),('Lowerbounds','Upperbounds'),'best') plot([0,1],[0,1],color='#999999',linestyle='') xlabel('Week 1') ylabel('Week 2') xticks(functions.upperboundsweek1+functions.lowerboundsweek1,' '*len(functions.upperboundsweek1+functions.lowerboundsweek1)) yticks(functions.upperboundsweek2+functions.lowerboundsweek2,' '*len(functions.upperboundsweek2+functions.lowerboundsweek2)) for function,x,y in map(None,functions.shortnames,functions.upperboundsweek1,functions.upperboundsweek2): annotate(function,xy=(x,y),size=8,color='b') for function,x,y in map(None,functions.shortnames,functions.lowerboundsweek1,functions.lowerboundsweek2): annotate(function,xy=(x,y),size=8,color='g') On Tue, 20080226 at 16:51 +0000, chombee wrote: > I'm having a couple of problems drawing a basic relational scatter plot. > (Specifically, it's called a dotdashplot in the book I have and is > described as "framing the bivariate scatter with the marginal distribution > of each variable.")
