Best way to get custom plot input in iPython module?

I have a module that will be used in iPython.

I would like the user to enter everything necessary to create the graph-x, y, label, line width, etc.

This way the user can do something like this:

In[1] import this_script
In[2] x=range(0,10)
In[3] y=x
In[4] magically_exposed_function plot(x,y,'r+', linewidth=2)

This means that my function gets a line graph (x, y, 'r +', line width = 2). This can be analyzed by the x and y values ​​found in the iPython namespace using ip.user_ns, but I'm still stuck with what to do with "r +" and line width = 2. Ideally, I would like to be able to:

a) import the entire iPython namespace so that I have available x and y values ​​and

b) throw out the whole line in plot ()

As for b), having something like:

plot_string = x, y, 'r+', linewidth = 2
plot(plot_string)

, , .

? ?

(x, y), ?
