I am looking for a way to create a bitmap image from a timeseries.
The timeseries is per minute for one year. It has 24x60 = 1440 entries per day.
I need a bitmap per year black and white color 365 x 1440
How to create a bitmap is clear due to this answer
My main issue is to create a matrix 1440 x 365 from a minute timeseries...
Thx
