i plotted 2 pandas series same dataframe same x axis , worked out fine. however, when tried manually create legend, appears title , not content. i've tried other solutions without luck. here's code: fig = plt.figure() ax1 = fig.add_subplot(111) ax2 = ax1.twinx() width = .3 df.tally.plot(kind='bar', color='red', ax=ax1, width=width, position=1, grid=false) df.costs.plot(kind='bar', color='blue', ax=ax2, width=width, position=0, grid=true) ax1.set_ylabel('tally') ax2.set_ylabel('total cost') handles1, labels1 = ax1.get_legend_handles_labels() handles2, labels2 = ax2.get_legend_handles_labels() plt.legend([handles1, handles2], [labels1, labels2], loc='upper left', title='legend') plt.show() plt.clf() maybe have reason way, if not, easier: in [1]: import pandas pd import numpy np import matplotlib.pyplot plt # optional, better looking import seab

can use cmsis, hal, tm libraries stm32f407 discovery board eclipse, without stm32cube? according link http://www.carminenoviello.com/en/2015/06/04/stm32-applications-eclipse-gcc-stcube/ can eclipse & stm32cube. wonder if can same thing without stm32cube. since i'm using os x, impossible install stm32cube, in order use gpio library need use cmsis, hal, tm libraries. you might able used older "standard peripheral driver" model - distributed set of driver files specific chip. these libraries no longer supported , replaced stm32cube generates equivalent code - better support hardware abstraction still useable. search "stm32f4xx_stdperiph_driver" locate libraries (which include standard peripheral drivers , cmsis).
