Question

我正在尝试将d3.js可视化应用于2层层次数据（此示例具有4个层次）。尽管有很多麻烦，我还是很想让它正常工作。我有两个问题我什至不知道从哪里开始：

1）将JSON数据更改为局部变量，然后从php数组以所需格式提供变量和 2）更改为分组的分层条形图。（每当我寻求有关层次图和分组图的帮助时，我都会提出在两者之间转换的问题）

现在，我的数据存储在两个这样排列的php数组中

ZedGraph.ZedGraphControl zedGraphControl1 = new ZedGraph.zedGraphControl1();
ZedGraph.ZedGraphControl zedGraphControl2 = new ZedGraph.zedGraphControl2();
private void InitializeEvents()
{
    zedGraphControl1.ZoomEvent += ZedGraphControl1_ZoomEvent;
    edGraphControl2.ZoomEvent += ZedGraphControl2_ZoomEvent;
}

private void ZedGraphControl1_ZoomEvent(ZedGraph.ZedGraphControl sender, 
ZedGraph.ZoomState oldState, ZedGraph.ZoomState newState)
{
    double zoomFraction = sender.ZoomStepFraction;
    PointF centerPt = this.deviceControl1.mousePt;
    ZedGraph.GraphPane pane = sender.MasterPane.FindChartRect(centerPt);

    //this.deviceControl2.zedGraphControl1.ZoomS

    //ZoomPane(pane, zoomFraction, centerPt, 
    this.deviceControl1.zedGraphControl1.IsZoomOnMouseCenter);
}

private void ZedGraphControl2_ZoomEvent(ZedGraph.ZedGraphControl sender, 
ZedGraph.ZoomState oldState, ZedGraph.ZoomState newState)
{

}

我当然有一个包含

的数组

Array 1: FoodsAtStore1
FoodsAtStore1['GroupID1']['Apples'] = 3
FoodsAtStore1['GroupID1']['Bananas'] = 10
FoodsAtStore1['GroupID2']['Cheerios'] = 10

Array 2: FoodsAtStore2
FoodsAtStore2['GroupID1']['Apples'] = 40
FoodsAtStore2['GroupID1']['Bananas'] = 3
FoodsAtStore1['GroupID2']['Cheerios'] = 10

用本地数据而不是json修改d3.js示例，并更改为分组条形图（分层条形图）
