Hi,
The Material charts don't yet support the option to change a particular
series color.

Hi ,
I have a requirement to grey out the legends and hide the lines once user
clicks on the legend. However, the lines are getting hidden but the legend
is not getting greyed out. The same piece of code works with all other
visualization charts. The code is as below.
google.visualization.events.addListener(chart, 'select', function () {
var sel = chart.getSelection();
// if selection length is 0, we deselected an element
if (sel.length 0) {
// if row is undefined, we clicked on the legend
if (sel[0].row === null) {
var col = sel[0].column;
if (columns[col] == col) {
// hide the data series
columns[col] = {
label: data.getColumnLabel(col),
type: data.getColumnType(col),
calc: function () {
return null;
}
};
// grey out the legend entry
series[col - 1].color = '#CC';
}
else {
// show the data series
columns[col] = col;
series[col - 1].color = null;
}
/* var view = new google.visualization.DataView(data);
view.setColumns(columns);
chart.draw(view, options);*/
var view = new google.visualization.DataView(data);
view.setColumns(columns);
chart.draw(view, options);
}
}
});
anybody has an idea, why isnt working?
