Hi,

I have an issue with plotting a scatter plot combine with bar graph.

x-axis is exchange rate (usd)
y-axis is stock market return (mkt)
bar graph is net supply and net demand

I would like to plot exchange rate and market return as scatter plot with corresponding net supply and net demand as bar graph only period that net demand or supply not equal to zero but I don't know how to plot this.

Please refer to the picture below:
