If I have a percentage of a pie chart say 90% is there a way in dimple to create a pie chart that only shows 90% and the other 10% is a missing slice? Thanks.
var arc = d3.arc()
.startAngle(0)
.endAngle(Math.PI * 2);
Will set your start angle at 0, and then end at 2PI. you can multiply this however you wish to get your desired angle.
var svg = d3.select("body")
.append("svg")
.attr("width", 200)
.attr("height", 200)
.append("g")
.attr("transform", "translate(100,100)");
var arc = d3.svg.arc()
.innerRadius(0)
.outerRadius(70)
.startAngle(0)
.endAngle(2 * Math.PI * 0.9);
svg.append("path")
.attr("class", "arc")
.attr("d", arc);
