d3.js&nvd3.js - 如何设置y轴范围

var chart;
nv.addGraph(function() {
  chart = nv.models.lineChart()
    .margin({left: 100})  // Adjust chart margins to give more space for y-axis labels
    .useInteractiveGuideline(true)  // We want nice looking tooltips and a guideline!
    .showLegend(true)       // Show the legend, allowing users to turn on/off line series.
    .showYAxis(true)        // Show the y-axis
    .showXAxis(true)        // Show the x-axis
    .forceY([0, 100]);      // Set the y-axis range from 0 to 100

  // Format the y-axis labels as percentages.
  chart.yAxis
    .tickFormat(d3.format(',.2%'));

  // Load the data into the chart.
  d3.select('#chart svg')
    .datum(data)
    .call(chart);

  // Update the chart when the window resizes.
  nv.utils.windowResize(function() { chart.update() });

  return chart;
});
