How do I increase the line thickness of my Seaborn Line

Question

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()

This is what my lineplots look like right now.

Answer 1

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

Answer 2

You need to specify the linewidth parameter = desired width
