Show line in a chart depending of multiple selections in a filter

[new020]

Hello, 

I have a line chart with 5 different expresions.

I create a intline for the filter pane and where the users could multiple selections of this expresions and compare the lines. 

In the settings of the  line chart i´m trying to use the field "visibility conditions" of each measure for for managing when the line should appear but, something i´m doing wrong because when i select two selections in the filter, only shows one.

Could you please help me?

Thanks in advance for your help,
