changing the marker size in python seaborn lmplot

Question

I am trying to change the size of the lmplot markers in seaborn. I have tried passing 's' or 'size' as arguments and neither of them work.

lm = sns.lmplot(x="totalX",y="NormI", hue="Data Type", data=df, palette="Set1", legend_out=False, S=20)

I have tried "s", "markersize", "size" I get no effect. I want to make the data points larger on the plot. Any help is much appreciated.

Answer 1

You want to use scatter_kws={"s": 100}

As in:

lm = sns.lmplot(x = "totalX", y = "NormI", hue = "Data Type", data = df, palette="Set1", legend_out=False, scatter_kws={"s": 100})

You can amend the integer value (currently 100) to change the size of the markers.

I don't know what your hue or palette data are, but this should work nonetheless.

Answer 2

I know this question specifies lmplot but thought I would add an answer for how to do this with a seaborn scatterplot.

df = sns.load_dataset("anscombe")
sp = sns.scatterplot(x="x", y="y", hue="dataset", data=df)

And to change the size of the points you use the s parameter

sp = sns.scatterplot(x="x", y="y", hue="dataset", data=df, s=100)
