## Calculate the Pertectage of the current Coronavirus

Hey guys for the current corona virus i have built a webscraper and get the following raw data.

I would like to calculate the "Death rate" in power bi by using a formula or something else.

My Idea is (only for China please)

Death rate: 100 / confirmed cases (7 days before the latest update) * Deaths from the current update.

or in Raw data

Death rate: 100 / 834,26 (01-24-2020,18:06,China) * 259 (02-01-2020,02:02,China)

I get an Update multiply times a day. So we need to focusing on Date (02-01-2020 - 7 Days = 01-24-2020)

Hope you can help me with an formular

Thanks Guys.

Hi, @Anonymous

Typically, your data model will contain a calendar table. In fact, it is usually better to aggregate data by year and month using columns of a calendar table (containing one row for each day) instead of  extracting the date parts from a single column of type date or datetime in calculated columns.

For further information, you may refer to the following links.

You can use relative date slicer : https://docs.microsoft.com/en-us/power-bi/visuals/desktop-slicer-filter-date-range

Or you can use a rolling 7 day measure. example

``Rolling 7 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],maxx(sales,Sales[Sales Date]),-7,DAY))   ``

In both case prefer a date calendar table.

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s.
