How do I set up column charts' x values in 'm' ie. 300m, 600m etc

I am learning charting in Excel. How do I display x values axis as 300m,
600m, 900m while the values displayed inside the columns are 256.4, 488.7 and
822.3

You make an XY chart not a Line chart. Line charts are used when the
x-values are categories (text or numbers that are not used numerically like
serial numbers)
best wishes
