首先，正如您在图像中看到的，Y 轴网格线是双倍的。有什么方法可以将它们从 y1 或 y2 轴上移除？
第二个问题如何强制Y轴从0开始？我试过这个：
chart.bars1.forceY([0]);
chart.lines1.forceY([0]);
但这不起作用，对这些问题有什么想法吗？
Javascript代码
var data = graphData();
nv.addGraph(function() {
var chart = nv.models.multiChart()
.margin({top: 30, right: 60, bottom: 50, left: 70})
.color(d3.scale.category10().range());
chart.xAxis.tickFormat(function(d) {
var dx = data[0].values[d] && data[0].values[d].x || 0;
return d3.time.format('%x')(new Date(d))
});
chart.yAxis1
.tickFormat(d3.format(',.f'));
chart.yAxis2
.tickFormat(d3.format(',.f'));
d3.select('#chart svg')
.datum(data)
.transition().duration(500).call(chart);
return chart;
});
function graphData() {
return <? echo json_encode($graph, JSON_NUMERIC_CHECK) ?>
.map(function(series) {
series.values = series.values.map(function(d) { return {x: d[0], y: d[1] } });
return series;
});
}
结果
