Actually, I discovered today that this is possible. You can use step() to achieve what you want: http://matplotlib.sourceforge.net/examples/pylab_examples/step_demo.html > > Before: > > x = arange(0, 10, 1) > y = x * (10.0 - x) > plot(x, y) > > After: > > x = arange(0, 10, 1) > x_m = x - 0.5 # left-hand midpoints > x_p = x + 0.5 # right-hand midpoints > y = x * (10.0 - x) > x_all = dstack((x_m, x, x_p)).flatten() > y_all = dstack((y, y, y)).flatten() > plot(x_all, y_all) > > If your question is the latter, you can toggle the hold state just by > calling > > hold() > > Hope this helps. > > > > > see the figure > > > > Thank you > > > > -- > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > > *Satish Maurya* > > *Research Scholar* > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > > -- > Damon McDougall > http://damon-is-a-geek.com > B2.39 > Mathematics Institute > University of Warwick > Coventry > West Midlands > CV4 7AL > United Kingdom -- Damon McDougall http://damon-is-a-geek.com B2.39 Mathematics Institute University of Warwick Coventry West Midlands CV4 7AL United Kingdom ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
