Set the location of the textItem with respect to a specific axis. If the
line is vertical, the location is based on the normalized range of the
yaxis. Otherwise, it is based on the normalized range of the xaxis.
Set the location of the label. param is a list of two values.
param[0] defines the location of the label along the axis and
param[1] defines the shift value (defines the condition where the
label shifts from one side of the line to the other one).
