//Define X axis
var xAxis = d3.svg.axis()
.scale(xScale)
.orient("bottom");
//Create X axis
svg.append("g")
.call(xAxis);
效果:
变成刻度尺:
.axis path,
.axis line {
fill: none;
stroke: black;
shape-rendering: crispEdges;
}
.axis text {
font-family: sans-serif;
font-size: 11px;
}
调整坐标位置到下面:
svg.append("g")
.attr("class", "axis")
.attr("transform", "translate(0," + (h - padding) + ")")
.call(xAxis);
效果:
var xAxis = d3.svg.axis()
.scale(xScale)
.orient("bottom")
.ticks(5); //Set rough # of ticks
效果:
//Define Y axis
var yAxis = d3.svg.axis()
.scale(yScale)
.orient("left")
.ticks(5);
同样设置起始坐标
//Create Y axis
svg.append("g")
.attr("class", "axis")
.attr("transform", "translate(" + padding + ",0)")
.call(yAxis);
效果:
var formatAsPercentage = d3.format(".1%");
xAxis.tickFormat(formatAsPercentage);
