hcpxy_remove_point(proxy, id = NULL, i = NULL, redraw = TRUE)
proxy: A higchartProxy object.id: A character vector indicating the id of the series to update.i: The index of the point in the data array. Remember js is 0 based index.redraw: Whether to redraw the chart after the point is added. When adding more than one point, it is highly recommended that the redraw option be set to false, and instead Highcharts.Chart#redraw is explicitly called after the adding of points is finished. Otherwise, the chart will redraw after adding each point.Useful links
