May i make two suggestions that may improve the charts?
I was wondering if you could add a small column on the left with de percentage of change YTD for each week?
And since at least Nintendo and Sony have Financial Years ending the 31st of march every year, could you add a line in the bottom of each chart with the cumulative sales since first week of april 2019?
This way we could see easily what the FY2019 sales are?
You could do that for FY2020 after the 31st of march 2020
Just suggestions, let me know what you think :)
