I am trying to get pandas to overlay a bar plot and a line plot. The two series have different scales so I want the values to be plotted on two "y" axes. I cannot get pandas to show the "bar" and "line" plots together.
from pandas import DataFrame df_eg = DataFrame() df_eg=DataFrame(data=[(1212,231),(9283,624),(11734,943),(12452,1037),(16766,1037),(120,113)],index=[2014,2015,2016,2017,2018,2019],columns=["Release","Hold"])
This gives the DataFrame
Release Hold 2014 1212 231 2015 9283 624 2016 11734 943 2017 12452 1037 2018 16766 1037 2019 120 113
Now if I try to plot the "Release" as a bar chart and the "Hold" column as lines with twin axes I get only the line.
fig, ax = plt.subplots() ax2 = ax.twinx() plt.hold(False) df_eg["Release"].plot(ax=ax,kind="bar") df_eg["Hold"].plot(ax=ax2, style='r-', secondary_y=True) ax.legend(loc='best')
If however I plot both as lines . Both the values show up. I am wondering how to make the bars and lines show up on the same plot. I am using pandas version '0.16.2' and matplotlib version '1.3.1'.
fig, ax = plt.subplots() ax2 = ax.twinx() plt.hold(False) df_eg["Release"].plot(ax=ax,kind="line") df_eg["Hold"].plot(ax=ax2, style='r-', secondary_y=True) ax.legend(loc='best')
