Can we make the high and low valuations on the charts 1/3 or 1/5 as thick as they currently are now please? Can we also add a 50% reduction in brightness to these lines if they still appear strong?
They should resemble the verticle purple lines in the background of the chart that shows the time period. 

Would be it be difficult to add a checkbox on the charts so we only have 1 chart, and people could layer them according to what they want to see. For example, 1 chart, but it has a checkbox on the top right-hand side that says Add High and Low Valuation Points. When they click the box, on the chart it would add the data points in.

I'm not sure if it's feasible or makes sense, but we can discuss it tomorrow morning if you would like.
