I’m using the gRaphael linechart plugin, and I would like to be able to change my hover tags to hover only for individual lines, not all lines at the same time.
The reason is because I have an invisible line that I don’t want users to see, but it’s set to a value of 0 so the y axis always starts at 0. If I set the tags to appear upon hover, I also see the tags for the invisible line. I want to set it so that the invisible line doesn’t have any hover tags.
Here’s what I have:
var lines = r.g.linechart(
40, //x start
0, //y start
chartWidth, //width
300, //height of chart in pixels
datesCount, //amount of x coordinates
[invisibleLine, locationViews, locationClicks], //array of y coordinates
{//options
nostroke: false,
axis: "0 0 1 1",
axisxstep: rows-1,//how many x interval labels to render
symbol: "o",
colors: ["transparent", "#BE6228", "#33312F", "#66625E", "#BFBDBB", "#E79645"]
}).hoverColumn(function(){
//adds hover tags
this.tags = r.set();
for (var i = 0, ii = this.y.length; i < ii; i++) {
this.tags.push(r.g.tag(this.x, this.y[i], this.values[i], 175, 0).insertBefore(this).attr([{fill: "#fff"}, {fill: this.symbols[i].attr("fill")}]));
}
}, function () {
//removes hover tags
this.tags && this.tags.remove();
}
);
Thanks for any help!
