Obtain Javascript array from a dygraph created with csv

[Rafa]

Dygraph parses csv data in an array, so my question is, there's a way
to obtain this array to avoid a new csv parsing?

[Rafa]

I've found a way:

var data = new Array();
var g = new Dygraph(document.getElementById("chart"),"test.csv",{});
for(var i=0;i<g["rawData_"].length;i++)
{
data[i] = g["rawData_"][i];
}

I don't know if it's the best way but works.

Yep, that works, but may be unsafe.

Remember you can always use the native format instead of CSV
(parsing is faster when using the native array, too).

Yes I know, but csv data are given. Why unsafe?

Who is giving the CSV format? Surely someone came up with a script that generates this CSV? Simply create a json object instead of CSV and you should be good to go - this is what I've done. It's a bit more work to generate the data, but the parsing is much, much faster.

The trailing underscore in "rawData_" indicates that it's a private
member of dygraphs. I may change its name or remove it entirely in a
future refactor. Your code will work now, but there's no reason to
think that it will work in the future.

The CSV format is given by a closed application. I'll investigate
about json object, thanks.
