[英]D3.js : Uncaught TypeError: Cannot read property 'document' of undefined
[英]d3.js - Uncaught TypeError: Cannot read property 'data' of undefined
我一直陷入2個我無法弄清楚的錯誤......我正在嘗試用一些后端數據構建一個Scatter Plot。 BackEnd向我發送了一個Javascript對象(tabularData),其中包含我需要的信息,並使用它來創建圖形。 我正在使用ExtJS 4.2.2和最現代版本的d3.js和nv.d3.js
第一個錯誤是一個未被捕獲的類型錯誤似乎抱怨nv.d3.js
Uncaught TypeError: Cannot read property 'data' of undefined nv.d3.js:11193
(anonymous function) nv.d3.js:11193
attrFunction d3.js:597

d3_selectionPrototype.each d3.js:883
d3_selectionPrototype.attr d3.js:580
updateInteractiveLayer nv.d3.js:11192
第二個錯誤是與d3.js有關的錯誤
Error: Invalid value for <g> attribute transform="translate(NaN,5)" d3.js:591

我很確定它與d3.select有關,但由於buildData創建了一個合法的Object,因此它失敗是沒有意義的。 我也認為這可能是因為我的很多x值和y值是相同的,但是使用nvd3.org上的實時代碼散點圖示例告訴我這不是原因。
這是我的實際參考代碼......
buildScatterPlot: function buildScatterPlot(tabularData){
Ext.vcops.chrome.D3js.load(function() {
Ext.vcops.chrome.nvd3.load(function(){
nv.addGraph(function() {
var chart = nv.models.scatterChart()
.showDistX(false) //showDist, when true, will display those little distribution lines on the axis.
.showDistY(false)
.transitionDuration(350)
.color(d3.scale.category20().range());
//Configure how the tooltip looks.
chart.tooltipContent(function(key) {
return '<h3>' + key + '</h3>';
});
//Axis settings
var xAxisLabel = tabularData.columns[1].label;
var yAxisLabel = tabularData.columns[2].label;
var xFormat;
var yFormat;
var xUnitId = tabularData.columns[1].unit === null ? null : tabularData.columns[1].unit.unitId;
var yUnitId = tabularData.columns[2].unit === null ? null : tabularData.columns[2].unit.unitId;
switch(xUnitId){
case "percent":
xFormat = '.02%'
break;
case null:
default:
xFormat = 'd'
break;
}
switch(yUnitId){
case "percent":
yFormat = '.02%';
break;
case null:
default:
yFormat = 'd';
break;
}
chart.xAxis
.axisLabel(xAxisLabel)
.tickFormat(d3.format(xFormat));
chart.yAxis
.axisLabel(yAxisLabel)
.tickFormat(d3.format(yFormat));
var d3data = buildData(xUnitId, yUnitId);
console.log(d3data);
d3.select('#chart svg')
.datum(d3data)
.call(chart);
nv.utils.windowResize(chart.update);
return chart;
});
/**************************************
* Data generator
*/
function buildData(xUnitId, yUnitId) { //# groups,# points per group
var data = [];
var skipped = 0;
for (var i = 0; i < tabularData.totalRowCount; i++) {
var xVal;
var yVal;
if(tabularData.rows[i].cells[2].renderedValue === "-"){
skipped++;
continue;
}
switch(xUnitId){
case "percent":
xVal = tabularData.rows[i].cells[1].value / 100.0;
break;
case null:
xVal = tabularData.rows[i].cells[1].value;
break;
}
if(tabularData.rows[i].cells[2].renderedValue === "-"){
skipped++;
continue;
}
switch(yUnitId){
case "percent":
yVal = tabularData.rows[i].cells[2].value / 100.0;
break;
case null:
yVal = tabularData.rows[i].cells[2].value;
break;
}
if(xVal === null || yVal === null){
continue;
}
console.log(xVal);
console.log(yVal);
data.push({
key: tabularData.rows[i].objectIdentifier.resourceKey.resourceName,
values: []
});
data[i-skipped].values.push({
x: xVal,
y: yVal,
size: Math.random() //Configure the size of each scatter point
});
}
return data;
};
});
});
}
對於我的問題,結果證明這與d3.v3不兼容。 我使用的是d3.v3,但是nvd3的穩定版本使用d3.v2: https : //github.com/novus/nvd3/commit/7e9b8c013c4d8e8ad5775062c438c842bc112585
我通過包含nvd3 / lib中提供的d3.v2版本解決了這個問題: https : //github.com/novus/nvd3/blob/master/lib/d3.v2.min.js
