candlestick2_ohlc plotting alignment problem

[Chu-An, Huang]

While using candlestick2_ohlc plotting, the starting point and the ending point are not located at the origin, left some space.

Is there any way to set the start at the origin?

Assuming your first argument is the Axis object, ax, you can use

ax.margin(x=0)

or equivalently

ax.set_xmargin(0)

The default can be controlled via a matplotlibrc file, or by directly setting

plt.rcParams['axes.xmargin'] = 0
