-***Logarithmic scale does not properly show negative numbers!***

That's [true](https://canvasjs.com/forums/topic/negative-values-with-logarithmic-scale/), and [very hard to work around](https://canvasjs.com/forums/topic/negative-values-with-logarithmic-scale/)

## Changelog

### 06.12.2020

- Changed the way rolling average is calculated: a rolling average over `n` days for the current day is now calculated from data from the day and `n-1` proceeding days, instead of centering the rolling average on the selected day.

Fixes #1.

- The above also means we can easily support even numbers for the number of days a rolling average is calculated over. So we do. And as a cherry on top, rolling average over a period of up to 31 days can be selected; there are no and never have been any restrictions over period if entered directly in the url (for example, here's a [65-day rolling average of new cases in USA](https://rys.io/covid/#delta,average:65;united-states))
