I want the data in column 1 to be the Y axis scale and the data in columns 2
& 3 to show as a trend line in the chart. I have played with this 10 ways to
Sunday and can't find how to do this.

How do I identify the Row 1 to contain column headings. When I import it
asks me but I typed these in and it shouldn't be this well hidden.

Thanks in advance.
