I've finally managed to wrangle my hexbin distribution plot into something almost pretty.
import seaborn as sns
x = req.apply_clicks
y = req.reqs_wordcount
sns.jointplot(x, y, kind="hex", color="#5d5d60",
joint_kws={'gridsize':40, 'bins':'log'})
But I'm hoping to overlay a regression line on top of it, and can't figure out how to do so. For instance, the regression line seems to occupy the marginal plot when I add regplot to the code:
x = req.apply_clicks
y = req.reqs_wordcount
z = sns.jointplot(x, y, kind="hex", color="#5d5d60",
joint_kws={'gridsize':40, 'bins':'log'})
sns.regplot(x, y, data=z, color="#5d5d60", scatter=False)
How to include the regression line in the body of the chart?
You need to specify the axes you want the regplot
to appear on. Here is an example, with some made-up data:
import seaborn as sns
import numpy as np
x = 0.3 + 0.3 * np.random.randn(10000)
y = 0.1 - 0.2 * x + 0.1 * np.random.randn(10000)
mask = (y > 0) & (x > 0)
x, y = x[mask], y[mask]
g = sns.jointplot(x, y, kind="hex", color="#5d5d60",
joint_kws={'gridsize':40, 'bins':'log'})
sns.regplot(x, y, ax=g.ax_joint, scatter=False)
