Hi Bavesh
Thank you very much for your reply. I will work through the blog for question B.
The proposed solution for A would only set the crossing point of the x-Axis to the y-Axis at 100 and not rebase the time series themselves to 100. See this screenshot, I need the series all to start at 100 for correct comparability of the graphs in the chart.
Thank you very much for any help on this.
