I use a line graph with 3 or sometimes 4 axes with data. When my independent axis is the Left Axis, everything works fine. However, when I switch the graph to have the independent axis on the Bottom Axis, using the same data, TeeChart always returns a value of 0 for Chart.Axes.Left.Minimum
and Chart.Axes.Left.Maximum
after calling Chart.Draw
. Does TeeChart somehow treat the left axis differently from other axes? If not, can you give me some clues as to what I might be doing wrong? I am unable to provide the code as it is spread over a number of procedures.
Thanks and regards

Hello,
The axes are independent of each other.
They are dependant on the data in the series they are linked to, when set to Automatic
. So, when you have an axis set to a series that has no data, it may have Minimum
and Maximum
properties set at zero. This should change from the moment you add some data to any of the series linked to that axis, or when you manually set Minimum
and Maximum
properties, ie calling SetMinMax(min, max)
.
