I am doing
ax = df.plot(x=x_col, y=y_col, style=['o', 'rx'])
but I don't like that the data points are large circles. I have thousands of datapoints, so it makes the plot ugly. Any idea how I can make the dots smaller, i.e. have them be actual points, rather than circles? Or any alternative suggestions for this sort of scatterplot?
The DataFrame.plot() docs include the option to pass keyword arguments to the underlying matplotlib plotting method. As you can see here, there's an argument s for the dot size. So you should be able to:
ax = df.plot(kind='scatter', x=x_col, y=y_col, style=['o', 'rx'], s=12)
This is also illustrated in the pandas visualization docs.
The valid matplotlib marker styles include; '.' (point) and ',' (pixel).
So an alternative could be:
ax = df.plot(x=x_col, y=y_col, style=['.', 'rx'])
