Some of your X data might be non-numeric. Remove the horizontal
alignment formatting in that column: if any cells are not right aligned,
then it doesn't contain numerical data.

To fix: (a) choose Cells from the Format menu, click on the Number tab,
and choose an appropriate number format. (b) copy a blank cell, select
the cells that need fixing, and use Paste Special from the Edit menu,
and choose the Values and Operation - Add options.
