accessing data in the "select data" section when creating a chart

Hi,

There are more rows of data i need to get to within my chart data area below "Pines Wages". The three dots are inactive and I cannot scroll down any further to get to the data within my chart set. How do I get to the rows of data below "Pines wages"?  There are another 6 rows of data below Pines Wages. Pines wages on my data set is on row 52 and as you can see from the data range it goes to 58. I cannot get to any rows from 53 to 58.
