fast way of deleting dygraph series

following situation: Dygraph expects data in following format

var data = [[0,1,2],[1,2,3]]

which simplifies:

[[x0, y10, y20], [x1, y11, y21], ... , [xn, y1n, y2n]]

Now deleting a series - a line in the graph - means deleting every ykn from the data array.

var firstSeriesDeleted = [[0,2], [1,3]]

Question is: Is there an optimized way to delete out the series with a complexity less than o(n) ? I'm using lodash framework and basic JavaScript.

If you're content to simply hide the series, you can use the setVisibility method.

Redrawing the chart is going to require more time than modifying your data array, so don't worry too much about the time complexity of manipulating your data.
