Assume a DataFrame df with three Series, S1, S2 and S3.

I want to plot

• S1 with blue color and continuous-line,
• S2 with blue color and dashed-line,
• S3 with green color and continuous-line.

I could call the Series.plot() three times, but what if I want to use DataFrame.plot()?
In other words, I want to use the method df[[S1,S2,S3]].plot() but I have no ideas what parameters to pass to the method plot(). So far, I only found that I can pass a matplotlib colormap but that does not seem to solve my problem.

Use style option:

linestyles = ['b', 'b--', 'g']
df.plot(style=linestyles)
