stacked bar chart ticks

[Sandy Lynn]

I have a stacked bar chart based on two records in a found set, one for each year, tracks productive vs non-productive wages.

Linear scale with minimum and maximum values set.

when I use auto ticks I get 15 values from 0 to 50,000,000 when I select any other value for the number of ticks I get all the labels overlaid on each other at the 0 line.

Any suggestions about what I am doing wrong?
