I have a HighCharts chart with two series plotted. Each data point can be drilled down to show a sub-plot: http://jsfiddle.net/9phfzewj/21/
The problem I have is that when I click on an x-axis label I am taken to a sub-plot with two series shown. The x-axis labels of this sub-plot only correspond to one of the series being shown, and the x-axis title and chart title also only refer to one of the series. I would like to have the x-axis labels for each series shown (perhaps there could be a secondary x-axis?), and also be able to correctly change the titles.
Is anyone able to help me to improve this and fix the problems?
Many thanks,
David
