I have a line (JSCHART) chart with many many lines, each representing a 24hr period of the date range selected. It reminds me of like Widows Performance Monitor.

Just like performance monitor, I'd like to click on a series and turn the color to black so that I can see it among the many colored lines.

Anyone done anything like that?

I was thinking I could have the chart drill down to itself, pass the series id and change the color in the style sheet. Currently the series colors are automatically assigned so I'll probably have to take control of that.

I'll probably also want to capture the current color of the selected series so I can restore it when they click on another line.

I did play around with this a couple of months ago.

Mine was based on mouse-over on the legend to highlight the series.

I'll see if I can find the technique.

This is the example of events on charts I did.

It may give some insights on what you want to do.

OK, this is a bit complicated, but with the events, you can change colour with :

With what I did, I had to "backup" the colours so I could restore them on mouse out.

for (var cs=0;cs<eventobject.chart.series.length;cs++) {
	if (eventobject.chart.getSeries(cs)) {
		if (cs == eventobject.series) continue ;
		if (eventobject.chart.getSeries(cs)) {
			eventobject.chart.set({series: [{series:cs,color: MyColour }]});
		}
	}
}
eventobject.chart.redraw();

Can you use "seriescolor(#)=&Color1"
Or something like that?
Or, do you want the series colors to be always consistent throughout?
