 [Matplotlib-users] Control twinx series zorder: ax2 series behind ax1 series, or place ax2 on left, ax1 on right From: Jeff Kowalczyk - 2011-02-25 23:35:19 ```I am trying to plot multiple series on one axes and a bar chart on a shared x, new y axes. I'm using twinx. The following test code works, but I need to render the bar plot *behind* the line plots. Can I somehow control zorder globally within a figure? Alternatively, I could make the bar chart the first plot/axes ax1, but the position for its y-axis must be on the right, the line chart's y-axis on the left. Can this be controlled?
