“以不同于3的尺寸给出的行” Google图表 [英] "Row given with size different than 3" Google Charts
问题描述
我在名为Klipfolio的系统中使用Google Charts。一直在修补它好几天。好奇,如果其他人也尝试过相同的。这个问题对于Kipfolio来说并不是特别的,但我认为一点背景可能会有很大的帮助。
这是代码:
var _component = this;
var _dataModel = this.dataModel;
var thearray = $ .map(_dataModel,function(value,index){
return [value];
});
var thearrays =('['+ thearray.toString()+']');
var datadone =(JSON.parse(thearrays));
console.table(datadone);
google.setOnLoadCallback(drawChart);
函数drawChart(){
var data = new google.visualization.DataTable();
data.addColumn('string','From');
data.addColumn('string','To');
data.addColumn('number','Weight');
data.addRows([datadone]);
//设置图表选项。
var options = {
sankey:{
迭代:700,
节点:{
label:{
fontName:'Arial',
fontSize:12,
color:'rgb(74,74,74)',
bold:true,
italic:false
},
interactivity:true ,//允许你选择节点。
labelPadding:3,//标签和节点之间的水平距离。
nodePadding:20,//节点之间的垂直距离。
width:10,//节点的厚度。
颜色:[
'rgb(82,144,233)',//用于sankey节点的自定义调色板。
'rgb(113,179,124)',//节点将循环通过这个调色板
'rgb(206,226,55)',//给每个节点自己的颜色。
'rgb(239,209,64)',
'rgb(236,147,47)',
'rgb(225,77,87)',
'rgb(150, 89,148)',
'rgb(157,121,82)',
'rgb(154,146,137)']
}
}
};
//实例化并绘制我们的图表,并传入一些选项。
var chart = new google.visualization.Sankey(document.getElementById('sankey_basic'));
chart.draw(data,options);
}
console.table中的 _dataModel 变量输出为这: http://imgur.com/hQD9V2W 。
console.table中的 thearray 变量输出为: http://imgur.com/TFwkkfQ
当图表呈现时,它会抛出错误:
未捕获的错误:给出的行大小不同于3(表中的列数)
是否有其他步骤I应该采取消除这个错误?我是新来的使用JavaScript和对象/数组。我发现 thearray 变量有4列出现,但是问题出在哪里?
解析方案看起来像我的问题是在data.addRows函数中添加括号。所以,而不是:
data.addRows([datadone]);
没有生成,我将其替换为:
data.addRows(datadone);
感谢Henrik指引我查看数据源。一旦我验证了队形,我就可以找出问题并加以解决。图表看起来不错!
I'm using Google Charts inside of a system called Klipfolio. Been tinkering with it for days. Curious if anyone else has tried the same. This issues isn't particular to Kipfolio but I figured a little bit of background may go a long way.
This is the code:
var _component = this;
var _dataModel = this.dataModel;
var thearray = $.map(_dataModel, function(value, index) {
return [value];
});
var thearrays = ('['+thearray.toString()+']');
var datadone = (JSON.parse(thearrays));
console.table(datadone);
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'From');
data.addColumn('string', 'To');
data.addColumn('number', 'Weight');
data.addRows([datadone]);
// Sets chart options.
var options = {
sankey: {
iterations: 700,
node: {
label: {
fontName: 'Arial',
fontSize: 12,
color: 'rgb(74,74,74)',
bold: true,
italic: false
},
interactivity: true, // Allows you to select nodes.
labelPadding: 3, // Horizontal distance between the label and the node.
nodePadding: 20, // Vertical distance between nodes.
width: 10, // Thickness of the node.
colors: [
'rgb(82,144,233)', // Custom color palette for sankey nodes.
'rgb(113,179,124)', // Nodes will cycle through this palette
'rgb(206,226,55)', // giving each node its own color.
'rgb(239,209,64)',
'rgb(236,147,47)',
'rgb(225,77,87)',
'rgb(150,89,148)',
'rgb(157,121,82)',
'rgb(154,146,137)']
}
}
};
// Instantiates and draws our chart, passing in some options.
var chart = new google.visualization.Sankey(document.getElementById('sankey_basic'));
chart.draw(data, options);
}
The _dataModel variable outputs in console.table as this: http://imgur.com/hQD9V2W.
The thearray variable outputs in console.table as this: http://imgur.com/TFwkkfQ
When the chart renders, it throws up the error:
Uncaught Error: Row given with size different than 3 (the number of columns in the table)
Are there any other steps I should take to eliminate this error? I'm new to using javascript and objects/arrays. I see that the thearray variable has 4 columns that appear, but is that the issue?
Looks like my issue was adding the brackets on data.addRows function. So instead of:
data.addRows([datadone]);
which didn't generate, I replaced it with:
data.addRows(datadone);
Thanks Henrik for pointing me to look at the data source. Once I verified the formation, I was able to identify the issue and fix it. Chart looks great now!
