Graph2dでポイントが接続されない場合があります

Question

私はvis.js v。4.12.0を使用しています。私は時々Graph2dを使用していくつかのポイントが接続されていないことに気づいた。

.

私は、この動作は、ポイントの距離に依存すると思います。誰かがポイント接続を強制する方法を知っていますか？ selten98 @

：確かに、ここに私のコード：

for (var i in plot) { 
    groups.add({ 
     content: labelArray[i], 
     id: plot[i], 
     options: { 
      shaded: { 
       orientation: "bottom" 
      } 
     } 
    }); 

    for (var j in GD) { 
     if (GD[j].hasOwnProperty(plot[i])) { 
      items.push({ 
       group: plot[i], 
       label: { 
        className: "visibility-hidden label-group-" + labelArray[i], 
        content: GD[j][plot[i]].toFixed(1), 
        xOffset: -10/3 * GD[j][plot[i]].toFixed(1).length, 
        yOffset: 20 
       }, 
       x: new Date(GD[j].timestamp), 
       y: Number(String(GD[j][plot[i]]).replace(",", ".")) 
      }); 
     } 
    } 
} 

for (var i = 0; i < items.length; i++) { 
    if (i == 0) { 
     groups.add({ 
      content: groupId, 
      id: groupId, 
      style: "stroke:" + arr_color[properties], 
      options: { 
       shaded: { 
        orientation: "bottom", 
        style: "fill:" + arr_color[properties] 
       }, 
       drawPoints: { 
        styles: "stroke:" + arr_color[properties] + ";fill:" + arr_color[properties] 
       } 
      } 
     }); 
     items[i].group = groupId; 
     scope.labels[properties].max = Number(items[i].y).toFixed(1); 
     scope.labels[properties].min = Number(items[i].y).toFixed(1); 
    } else { 
     if (items[i].label.className == items[i - 1].label.className) { 
      if (items[i].x.getTime() - items[i - 1].x.getTime() > Number(type[1]) * 60 * 1000) { 
       groupId++; 
       groups.add({ 
        content: groupId, 
        id: groupId, 
        style: "stroke:" + arr_color[properties], 
        options: { 
         shaded: { 
          orientation: "bottom", 
          style: "fill:" + arr_color[properties] 
         }, 
         drawPoints: { 
          styles: "stroke:" + arr_color[properties] + ";fill:" + arr_color[properties] 
         } 
        } 
       }); 
      } 
      items[i].group = groupId; 
      scope.labels[properties].max = Math.max(scope.labels[properties].max, Number(items[i].y)).toFixed(1); 
      scope.labels[properties].min = Math.min(scope.labels[properties].min, Number(items[i].y)).toFixed(1); 
     } else { 
      groupId++; 
      properties++; 
      groups.add({ 
       content: groupId, 
       id: groupId, 
       style: "stroke:" + arr_color[properties], 
       options: { 
        shaded: { 
         orientation: "bottom", 
         style: "fill:" + arr_color[properties] 
        }, 
        drawPoints: { 
         styles: "stroke:" + arr_color[properties] + ";fill:" + arr_color[properties] 
        } 
       } 
      }); 
      items[i].group = groupId; 
      scope.labels[properties].max = Number(items[i].y).toFixed(1); 
      scope.labels[properties].min = Number(items[i].y).toFixed(1); 
     } 
    } 
} 

var container = document.getElementById("graph"); 
container.innerHTML = ""; 

var dataset = new vis.DataSet(items); 

var options = { 
    dataAxis: { 
     left: { 
      format: function (value) { 
       return Number(value).toFixed(1); 
      } 
     } 
    }, 
    drawPoints: { 
     style: "circle" 
    }, 
    orientation: "top", 
    showCurrentTime: true, 
    end: new Date(end), 
    max: new Date(end), 
    min: new Date(start), 
    start: new Date(start) 
}; 

startTime = options.start.getTime(); 
endTime = options.end.getTime(); 
var graph2d = new vis.Graph2d(container, dataset, groups, options);
