I am not 100% certain what you need. Do both strings contain 512 chars?

Take a look at the attached example. Look at the scripts on the
scripted dataset.

I have modified the example to illustrate how you could nest the data
set in another data set to get the initial string that you will be using
for the chart data set. Look at the script and look at the binding tab
for the chart. Specifically look at the parameters for the binding of
the chart which references the outer tables data value. For the two
field, do you want a second chart or a second series on the same chart?

Modify the scripted datasets and refresh the bindings on the chart and
table. Do refresh select the binding tab in the properties editor and
click on the refresh button. You will need to add another input
parameter to the nested dataset as well. Look at the attached modified
example.

This is an issue with the area chart type. You can bump the chart to
the left with some script but it will not extend to the furthest point
to the right. For example put a script like this in:
function beforeDrawSeries( series, seriesRenderer, context )
{
if( series.getSeriesIdentifier() == "Series 1" ||
series.getSeriesIdentifier() == "Series 2"){
var dpharray =
seriesRenderer.getSeriesRenderingHints().getDataPoints();
for( j=0;j<dpharray.length;j++){
var xval = dpharray[j].getLocation().getX();
dpharray[j].getLocation().setX(xval-100);
}
}
}
