Assume that I have some data, and I want to create a plot of this data by passing it to a custom plotting function (myplot()). I am using the matplotlib's modules in myplot().

I would like myplot() to return the handle to a figure, and not plot display the plot when I call this function. Here is a sample code and output from iPython.

enter image description here

I have two questions regarding this:

  1. Why do I still see a plot, even though I am assigning the output of myplot() to f?
  2. What do I need to supress this plot when I am assigning the output of myplot() to a variable?

This is only an iPython Notebook feature, right? Because I don't see a plot when I pass the figures around in IDLE. – Sukrit Kalra Jul 9 at 13:44

Start ipython with

ipython notebook

rather than

ipython notebook --pylab=inline

I think you do not have to start the whole notebook-session in non-inline-modus. You can control the inline-backend-behaviour with the following command. %config InlineBackend.close_figures = False This will prevent your plots from beeing closed (thus shown inside the browser) immediately. – ala Jul 9 at 14:16

If you do not want to start the whole notebook in non-inline-modus you can just use the following code:

%config InlineBackend.close_figures = False

def myplot(t,x):
    fig = figure()
    x = plot(t,x)
    fig.savefig('plot.png') # This is just to show the figure is still generated
    return fig

t = arange(0,6,0.01)
x = sin(t)

f = myplot(t,x)

This did not work. I still get the same output as shown in my question. – siva82kb Jul 10 at 13:54
