まず、画像でわかるように、Y 軸のグリッド線が 2 重になっています。y1 軸または y2 軸からそれらを削除する方法はありますか?

2 番目の質問は、Y 軸を強制的に 0 から開始する方法です。私はこれを試しました:

chart.bars1.forceY([0]);
chart.lines1.forceY([0]);

しかし、それはうまくいきませんでした。問題について何か考えはありますか?

Javascript コード

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;
    }); 
}

結果 二重グリッド線
