How to HIde rows based on User Selection

I have a requirement where in I have to hide some rows based on Plant Name selected by USer at the time of opening the report.

Here is the screen  shot:-

Here I am seeing two Tag Types MACT and Average when User selects  Luling Plant. But When User selects some other Plant I don't want to see Tag Type 'MACT' in this table.

We have a predefine filter for Plant.

How can I achieve that. The data in White Rows is Average values.

Please help.
