I'd like to make two lines using scatter chart. I'm successful in setting all points in 2 colors. Here's my example of setting 4 points in two colors

var data = [[1339538400,9,"red"],

But when I set these parameters:
scatter.Set('chart.line', true);
scatter.Set('chart.line.colors', ['red','green']);
All points get connected with a red line. My guess is the format of the data array, but changing the format all points just disappear.

Could someone shed a light on the way I could make two independent lines using two colors

Thank you.

Your data is set up for just one line - only a single dataset. So you'll need to alter it to something like this:

var data1 = [[1339538400,9,"red"],[1340229600,10,"red"]];
var data2 = [[1339538400,9.5,"green"],[1340229600,13,"green"]];

var myScatter = new RGraph.Scatter('cvs', data1, data2);

Or a variant on the above useful for when you're working with AJAX:

var myScatter = new RGraph.Scatter('cvs', [data1, data2]);

Thank you, putting the data as two different arrays solves this problem
Your speed of giving the solution is impressive. Thank you again.
