    Default [4.2] LineSeries highlights line and markers together. Feature to split it.

    [4.2] LineSeries highlights line and markers together. Feature to split it.


    Hello,

    Currently, a LineSeries highlights a line itself and markers together. It would be nice to have a config option not to highlight a line, i.e. highlight only markers.

    A config option can be called "highlightLine" and here is a possible override.

    Possible override
    Code:
    Ext.chart.series.Line.override({
        highlightItem: function() {
            var me = this,
                line = me.line;
                    
            Ext.chart.series.Line.superclass.highlightItem.apply(this, arguments);
            if (line && !me.highlighted && me.highlightLine !== false) { // added the third condition 
                if (!('__strokeWidth' in line)) {
                    line.__strokeWidth = parseFloat(line.attr['stroke-width']) || 0;
                }
                if (line.__anim) {
                    line.__anim.paused = true;
                }
                
                line.__anim = new Ext.fx.Anim({
                    target: line,
                    to: {
                        'stroke-width': line.__strokeWidth + 3
                    }
                });
                me.highlighted = true;
            }
        }
    });

    Moved your feature request over to the Bugs forum - makes it easy for me to push the request right to to the tracker - sorry for any confusion.

    Also, since we're on the subject of charts someone was recently asking for more events on charts and I wondered if you might want to weigh in:

    Thank you for that. At the moment I cannot remember any. Though sometimes I feel lack of events as well. So, I will think of. Also I will ask some our customers who intensively uses Charts.

    By the way, my main concern regarding Charts is this one.

    I would much appreciate any comments.
