[FIXED] How do I increase the line thickness for sns.lineplot?

Issue

I have a few seaborn lineplots and I can't figure out how to increase the width of my lines.

Here is my code

#graph 1
sns.lineplot(x="date", y="nps", data=df_nps, ax=ax1, label="NPS", color='#0550D0')
sns.lineplot(x="date", y="ema28", data=df_nps, ax=ax1, label="EMA28", color='#7DF8F3')
sns.lineplot(x="date", y="ema7", data=df_nps, ax=ax1, label="EMA7", color='orange')

#graph 2
dfz_nps_lineplot = sns.lineplot(x="date", y="nps", data=dfz_nps, ax=ax2, label="NPS", color='#0550D0')
dfz_nps_lineplot = sns.lineplot(x="date", y="ema28", data=dfz_nps, ax=ax2, label="EMA28", color='#7DF8F3')
dfz_nps_lineplot = sns.lineplot(x="date", y="ema7", data=dfz_nps, ax=ax2, label="EMA7", color='orange')

#graph3
dfp_nps_lineplot = sns.lineplot(x="date", y="nps", data=dfp_nps, ax=ax3, label="NPS", color='#0550D0')
dfp_nps_lineplot = sns.lineplot(x="date", y="ema28", data=dfp_nps, ax=ax3, label="EMA28", color='#7DF8F3')
dfp_nps_lineplot = sns.lineplot(x="date", y="ema7", data=dfp_nps, ax=ax3, label="EMA7", color='orange')

# formatting

plt.show()

Solution

As you can see from seaborn.lineplot documentation, the function accepts matplotlib.axes.Axes.plot() arguments, which means you can pass the same arguments you can to matplotlib function in this documentation.

If you want to simply adjust the width of your lineplots I find this the easiest: pass an argument linewidth = your_desired_line_width_in_float , for example, linewidth = 1.5 in your sns.lineplot() functions.

You can find additional possible arguments in the documentations linked.

Example output on random data:

seaborn.lineplot() without linewdith argument provided

seaborn.lineplot() with linewidth = 3
