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

    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)
