Hi All,

i would like to ask for a code assistance.
The attached code shows the seasonal behaviour
– quantity of up /down weeks from year to year in % (Histogram 1=100%)
– price percentage of the up /down weeks in %
– SumUp percentage of Price changing from Jan to Dec.

• I would like to know how to code the vertical line shown 52 weeks ago from todays date without showing the vertival lines to the left.
  How to eliminate the additional vertical lines to the left?
• Is it possible to change the background colour all 3 monthy repeating every year.
  For example:
  2018, Jan-Mar= dark green, Apr-Jun=mid green, Jul-Sep=light green, Okt-Dec= yellow
  2019, Jan-Mar= dark green, Apr-Jun=mid green, Jul-Sep=light green, Okt-Dec= yellow

– How is it possible to eliminate the fix variable of 2018 at the if loop at the beginning?

Many thanks for your support in advance.
Best Regards
