To change the way the chart data is plotted, complete the following steps:

1.   In the Properties window, expand the ChartArea node.

2.   Expand the node of appropriate axis.

3.   In Grid Minor, set Max and Min (maximum and minimum interval to display on axis) and set UnitMajor (numerical interval on axis).

For example, if Max is set to 20, Min is set to 0, and UnitMajor is set to 5, every fifth number will display 0, 5, 10, 15, and 20 on the axis.
