nv.d3.js折线图y轴问题

Question

我是nv.d3.js图书馆的新手。只是想在线图上绘制一些值。但该图表的表现非常奇怪。如下图所示，y轴水平显示。

如果我将图形更改为cumulativeLinegraph，则会正确渲染y轴，但这些值都会混乱。

这是我的代码

var chart = nv.models.lineChart()
                          .x(function(d) { return d[0]; })
                          .y(function(d) { return d[1] })
                          .showXAxis(true)
                          // .showYAxis(false)
                          // .color(d3.scale.category10().range())
                          .showLegend(true)
                          .useInteractiveGuideline(true);

            chart.xAxis.axisLabel("Date").tickFormat(function(d) {
                var format = '%m/%d/%y';
                d = d * 24 * 60 * 60 * 1000;
                // if (!(d instanceof Date)) {
                    d = new Date(d);
                    // if (param['scale'] == 'hour' || param['scale'] == 'minute') {
                    //   format = '%m/%d/%y %H:%M';
                    // }
                // }
                return d3.time.format(format)(d);
            }).tickValues(null);
            chart.yAxis.axisLabel("Count");

            // chart.xScale(d3.time.scale());

            // chart.yAxis.tickFormat(function(num){
            //     return floatToMins(num);
            // });

            d3.select('#inventoryGraph svg')
                .datum(cumulativeData())
                .call(chart);

            nv.addGraph(function() { return chart; });

            nv.utils.windowResize(chart.update);

样本数据是这样的

到目前为止，是否有人遇到过此问题。有什么想法吗？

Answer 1

我建议构建图表对象需要在addGraph函数中。使用代码d3.select ...您已经开始创建图形，稍后将传递给nvd3。

结果将是：

 nv.addGraph(function() {
var chart = nv.models.lineChart()
                          .x(function(d) { return d[0]; })
                          .y(function(d) { return d[1] })
                          .showXAxis(true)
                          // .showYAxis(false)
                          // .color(d3.scale.category10().range())
                          .showLegend(true)
                          .useInteractiveGuideline(true);

            chart.xAxis.axisLabel("Date").tickFormat(function(d) {
                var format = '%m/%d/%y';
                d = d * 24 * 60 * 60 * 1000;
                // if (!(d instanceof Date)) {
                    d = new Date(d);
                    // if (param['scale'] == 'hour' || param['scale'] == 'minute') {
                    //   format = '%m/%d/%y %H:%M';
                    // }
                // }
                return d3.time.format(format)(d);
            }).tickValues(null);
            chart.yAxis.axisLabel("Count");

            // chart.xScale(d3.time.scale());

            // chart.yAxis.tickFormat(function(num){
            //     return floatToMins(num);
            // });

            d3.select('#inventoryGraph svg')
                .datum(cumulativeData)
                .call(chart);



            nv.utils.windowResize(chart.update);
  });

检查小提琴： http://jsfiddle.net/b7xfahyw/

如果我按原样传递数组，你可以看到一切正常。

希望有所帮助
