plotOptions.heatmap.label.connectorAllowed

Allow labels to be placed distant to the graph if necessary, and draw a connector line to the graph. Setting this option to true may decrease the performance significantly, since the algorithm with systematically search for open spaces in the whole plot area. Visually, it may also result in a more cluttered chart, though more of the series will be labeled.
