Extending the answer by @user2467675, here’s how I did it:
def rand_jitter(arr):
stdev = .01 * (max(arr) - min(arr))
return arr + np.random.randn(len(arr)) * stdev
def jitter(x, y, s=20, c="b", marker="o", cmap=None, norm=None, vmin=None, vmax=None, alpha=None, linewidths=None, verts=None, hold=None, **kwargs):
return scatter(rand_jitter(x), rand_jitter(y), s=s, c=c, marker=marker, cmap=cmap, norm=norm, vmin=vmin, vmax=vmax, alpha=alpha, linewidths=linewidths, **kwargs)
The stdev
variable makes sure that the jitter is enough to be seen on different scales, but it assumes that the limits of the axes are zero and the max value.
You can then call jitter
instead of scatter
.
