In this case, you should either
- use one more digit in the number format (
0.0000
) on the left axis, or
- increase the distance between the labels on the left axis.
In a comment to the question, the OP confirmed that the number format should be changed.
To do this at runtime, you can do
MyChart.Axes.Left.AxisValuesFormat := '0.0000';
It is also possible to do this at design-time.
