We have a series that has the same Y values of all points and have a long fractional part.

The chart for calculating the size of the axis's labels uses rounding to some value.
In the case of equal values, rounding up to (1) occurs, and for the value of (12.345) the size of the label "12" instead of "12.345" will be calculated.

We found in the code that causes such behavior, and there is already a comment with a possible solution:

VCLTee.TeEngine:4347 (InternalCalcLabelsIncrement)

if IRangeZero then
         result:=1 // <-- TODO: What can we use instead of 1? A magnitude of Min?

Please check this issue
