javascript - In HighStocks, compare the values of the series against the previous value -


in highstock/highchart 3.0+ possible display series y-axis representation of change previous value. know can use plotoptions.series.compare represent y-axis change first data point in visible range.

so here result looking - if have following points on y-axis [100, 115, 110, 105, 120] want see following points plotted [+15, -10, -5, +20].

is possible? know can morph original input second array in example here, hoping avoid this, since tooltip need preserve first array.
