You can use the chart's Extent properties to force the labels to be in a 
given range (Chart1.Extent.YMax := 16.1, Chart1.Extent.YMin := 15.6; 
Chart1.UseXMax := true; Chart1.UseXMin := true). But then these labels 
won't update automatically after you, for example, added new data which 
outside this range. Therefore, I think that this is not the correct 
solution.

You somehow must have misconfigured the axis, because normally an axis 
shows labels even if the chart is empty. It is hard to tell from the 
distance what you did wrong. Can you pack the chart part of your program 
into a little compilable demo which shows the issue and which you can 
add as an attachment?
