Creates a new chart based on a line chart. The chart puts all events at date = 0 and than compares the evolution of the series after the event date.
series (QFSeries) – Series usually with values of an index or level of interest rates
event_dates_list (Iterable[datetime]) – A list specifying the dates of the events that we would like to compare. Each date will create a new series in the chart
title (str) – The title of the graph, specify
Noneif you don’t want the chart to show a title.
samples_before (int) – Number of samples shown on the chart that are before the event date
samples_after (int) – Number of samples after the event date that are plotted on the chart
rebase_method (RebaseMethod) –
Specifies the way in which the data is normalised at the date of the event.
’divide’ - will divide all the values by the value at the date of the event
’subtract’ - will subtract the value at the event from the whole sample
’none - will show the value as is (no rebasing).
