Thank you for your reply.
Apology for not making query clearer. I am trying to create a multi-series
line chart, which is triggered by selecting one or more names, from the
category filter control. The line chart should, create a multi-series,
when one or more 'name' column is selected from the category filter
control.
I was originally using the above example, to design this functionality. So
far, I am able to select multiple name's values, from the category filter
control, from the function below, *however its failing to create line chart
for the selected 'name' values from the category filter control.*
Is function still plausible? if so, how can I setup my function below
further, so it can, render multi-line graph, from the select multiple
name's values (category filter control).
google.visualization.events.addListener(control, 'statechange',
function () {
var filteredData = control.getState();
// get a list of all the labels in column 0
var group = filteredData.getDistinctValues(0);
for (var i = 0; i < state.selectedValues.length; i++) {
row = columnsTable.getFilteredRows([{ column: 1, value:
state.selectedValues[i] }])[0];
view.columns.push(columnsTable.getValue(row, 0));
}
var view = new google.visualization.DataView(filteredData);
view.setColumns(columns);
var groupedData = google.visualization.data.group(view,
[0], groupColumns);
line.setView({ columns: viewColumns });
line.setDataTable(groupedData);
line.draw();
});
The rest of code and can be found here (for further reference):

Any advice/hint would be much appreciated. Many thanks.
