Showing data values on graph with Pages

I made a graph with Pages (see attached pictures) and would like to show the exact values of my data on their respective axes. However, Pages automatically labels my axes with ranges (e.g., 2,500,000.00, 5,000,000.00, etc.) instead of the data values (e.g., 1,526,721.00 ...).

How can I get raw data values to appear on each axis?
