Line Chart not showing

[lilySixteen]

Hello,

I'm new to Power BI. Can anyone please let me know what causes the below issue and how to resolve it?

I imported 5 tables from an excel and was plotting them on the line chart. The first 4 line charts worked correctly. But the 5th chart showed nothing but the chart title (please see below picture). 

Thanks so much!

Lili

Looks like you have your measure in the Legend field when it should in the Values.
