Declaration: TMetaData.AxisCaption[dim: TDims]: string;
The array property AxisCaption controls the caption of the axis specified by the parameter dim. The parameter dim may take one of the following values: dimX, dimY, dimL and dimT for the x, the y, the layer and the timeslot axis, respectively.

Please mind the subtle differences between AxisCaption and AxisLabel: while AxisCaption is a label applied to the particular axis as such, AxisLabel corresponds to the individual labels of the pixels along an axis.

Hint 1: Please note that the caption of an axis must not be longer than 63 characters. Any excess characters are automatically cut.

Hint 2: In order to directly access the metadata of the currently loaded dataset you can use the pre-declared global variable MData.
