Extend the scale

[Krszt]

Hello,

I am using matplotlib to make a scatter-plot, here is the code:

if os.path.isfile("example.txt"):
    days_KECS, intensity_KECS = np.loadtxt("example.txt", unpack=True,
                               converters={ 0: mdates.strpdate2num('%Y%m%d')})
    plt.plot_date(x=days_KECS, y=intensity_KECS, fmt="ro")
    plt.title("KECS intensity datas")
    plt.ylabel("Intensity")
    plt.xlabel("Date")
    plt.grid(True)
    plt.show()
else:
    print("MISSING DATAS")

my question is, how can I set the y axis (intensity datas), that the max values wouldn't be on the edge, so the max value on the scale would be a bit bigger?
Thanks

Perhaps use matplotlib.pyplot.ylim()
