How to stop the second y - axis from dropping and showing 0 if there is no data?

[HopelessPBIuser]

Hi,

I have a Line and Stacked bar chart. The user can select several years for specific cities, the line follows the years from column to column. However there is currently not data for all years for all cities, so in the case that there is not data, the line drops down to 0 from the previous year value. 

I would like to stop it from dropping down to 0 in case there is no data and stop at the previous year value. 

Any way to achieve this?

Change your measure to properly return BLANK() if there is no data.
