How would I set a start date and end date?

[Anonymous]

I am doing a line chart visualization. My x-axis is a date field. I want to filter it so that the start date is 30 days ago and the end date is the current date. How would I do this in Power BI?

In Power BI Desktop, we can't directly fix a range on X-axis in a chart visual. If your data is up to today, you may try Visual Level filter to limit the TOPN dates based on the DateKey.

However, I think a better approach is creating a calculated table which keeps the latest 30 days data so that you just need to populate this 30 days table into your chart.

1. Add a calculated column in your source table for tagging if current rows is within in "latest 30 days"

If in latest 30 days = IF(DATEDIFF(Table[Date],TODAY(),DAY)>30,0,1)

2. Then create a calculated table basedd on this column.

Latest 30 Days Table = FILTER(table,Table[If in latest 30 days]=0)

You could create a calculated column like this:

DaysAgo = TODAY() - [Date] * 1.

Then just add a visual, page or report filter where DaysAgo is < 31
