Ken,
You can get the column labels from your DataTable data with
data.getColumnLabel(i). So use that expression instead of your
literal string value. In fact, you could use a loop to setup all of
the columns for your DataView, building a columns array that you then
pass to view.setColumns().

Daniel - this morning I just noticed that using the dataView
approach caused the labels to disappear from my chart legend.
They are in the 1st line (header) of the CSV file and previously
provided labels with the non-DataView approach.
But as soon as I add the DataView visualization the labels disappear.
I restored labels with sourceColumn options (as exampled below)
but would prefer to pass the labels in the CSV file for
generality. Is that possible? I couldn't discover a way to make
it work.

vardata =google.visualization.arrayToDataTable(arrayData,false);
varview =newgoogle.visualization.DataView(data);
view.setColumns([
{sourceColumn:0,type:"number",label:"Hour"},
{sourceColumn:1,type:"number",label:"Dwn"},
{sourceColumn:2,type:"number"},
{sourceColumn:3,type:"number",label:"Mid"},
....
....

Thanks.
