How to filter Dimension

[MK_8]

Hi All, 

I was working on a Chart with Dates columns on Dimension and I want to filter out the years with no data and less data, in the given case I want the chart to show data from 2015.

Thanks in advance.

As a calculated dimension as below thus suppressing null values.

IF(Year >= 2015, Year)

Alternatively, you can include this modifier in your expression.

({<Year = {">=2015"}>}
