[SciPy-user] small problem about scipy.gplt

Dear list, I am using scipy.gplt to display a series of plots using repeated calls like 'plot, xtitle, ytitle, title' etc. Everything works fine except that each command will re-plot the whole figure. I mean, plot will remove all titles and xtitle etc will add them one by one. The main figure will then shrink/enlarge in a circular manner. Is there a way to tell gplt to stop drawing until I finish a sequence of commands? Many thank in advance. Bo
