I have an Event Segmentation chart with two events, with greatly different amplitudes. I'd like to express them as a percentage change from a (start of period) baseline. This is common in finance. For example, here is a YTD comparison of two indexes (S&P 500 and a Cryptocurrency index). Note how each line is shown as a percentage change from the first time period inthe graph:
Any idea how to do it in Amplitude? Thanks!
