setBaseLine(baseLine)

Sets the baseline for the data representation.

Certain data representation, such as bars in bar layers and area in area layers, are drawn from a base line. The base line by default is y = 0.

For example, for a vertical bar layer, the bars start from y = 0 and grow upwards for positive data (assuming the y-axis is not reversed), and downwards for negative data.

This method can be used to modify the base line to other values.
