I like to switch x axis with y axis after plotting a graph with matplotlib? Any easy way for it? Thanks in advance.

Could you please add some more information as to what exactly do you mean by "switch x axis with y axis after plotting a graph"? Do you want to plot the axis transposed? Do you want to store transposed values?Jimmy Lee Jones– Jimmy Lee Jones2018-03-25 07:10:15 +00:00Commented Mar 25, 2018 at 7:10

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)

What is the first line this solution refers to? Does it mean that if there are >=2 lines, it will fail?

in case you want to switch multiple lines, simply put it in a loop! (e.g.
for line in ax.lines: ...
Bennimi
only work if axis have the same dtype tho!
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)

Thanks, but it is not the answer I am seeking. I am asking how to switch x and y axes after I have plotted all data.
Rotate the monitor 90 degrees and look at its mirror image. An O(1) solution.
