How to switch axes in matplotlib?

I like to switch x axis with y axis after plotting a graph with matplotlib? Any easy way for it? Thanks in advance开发者_如何学运维.

I guess this would be a way to do it in case you really want to change data of an existing plot:

execute this code first to get a figure:

# generate a simple figure
f, ax = plt.subplots()
ax.plot([1,2,3,4,5], [5,6,7,8,9])
ax.set_xlim([0, 10])
ax.set_ylim([0, 10])

and then use this to switch the data of an existing line

# get data from first line of the plot
newx = ax.lines[0].get_ydata()
newy = ax.lines[0].get_xdata()

# set new x- and y- data for the line
ax.lines[0].set_xdata(newx)
ax.lines[0].set_ydata(newy)

You can simply switch x and y parameters in the plot function:

I[3]: x = np.linspace(0,2*np.pi, 100)

I[4]: y = np.sin(x)

I[5]: plt.plot(x,y)

I[6]: plt.figure(); plt.plot(y,x)
