jQuery图形，按输入的图表自定义不起作用 [英] jQuery graph, chart custmization as per the inputs is not working
问题描述
最近，我尝试了莫里斯面积图，这是一个很好的方法.但是很难理解如何从那里获取数据.
Hi recently i tried Morris Area Charts , and it is good one . But the thing its difficult to understand how the data is fetched there .
我看过文档 https://morrisjs.github.io/morris. js/lines.html ，& 我在这里制作示例图
I have seen the document https://morrisjs.github.io/morris.js/lines.html , & i make sample graph here
var data = [
{ y: '2014', a: 50, b: 90},
{ y: '2015', a: 65, b: 75},
{ y: '2016', a: 50, b: 50},
{ y: '2017', a: 75, b: 60},
{ y: '2018', a: 80, b: 65},
{ y: '2019', a: 90, b: 70},
{ y: '2020', a: 100, b: 75},
{ y: '2021', a: 115, b: 75},
{ y: '2022', a: 120, b: 85},
{ y: '2023', a: 145, b: 85},
{ y: '2024', a: 160, b: 95}
],
config = {
data: data,
xkey: 'y',
ykeys: ['a', 'b'],
labels: ['Total Income', 'Total Outcome'],
fillOpacity: 0.6,
hideHover: 'auto',
behaveLikeLine: true,
resize: true,
pointFillColors:['#ffffff'],
pointStrokeColors: ['black'],
lineColors:['gray','red']
};
config.element = 'area-chart';
Morris.Area(config);
#area-chart{
min-height: 250px;
}
<head>
<meta charset=utf-8 />
<title>Morris.js Area Chart</title>
</head>
<body>
<h3 class="text-primary text-center">

<div class"row">
<div class="col-sm-12 text-center">

<div id="area-chart" ></div>

但是我现在有不同的要求.
But i have different requirement now .
在Y轴上，我必须输入年份，在x轴上，我必须在图表中显示以下数据.
In Y axis i have to put year and in x axis and i have to show the following data in chart .
Initial gain total_gain year
100 10 110 1
100 25 125 2
200 20 220 1
1200 180 1380 1
1200 720 1920 3
但是我不知道如何在图表中实现它.如果有人可以理解这项工作的原理，请帮忙
But i don't know how i can i implement this in chart . If some one can understand how this work then please help
推荐答案
函数getData只是将原始数据转换为正确的格式，因此与当前的morris-chart-configuration(ykeys).
The function getData just transforms the original data into the right format so that there is no format-conflict with the current morris-chart-configuration (xkey, ykeys).
尽管最有趣的部分是parseTime和xLabelFormat.通过设置parseTime false，您告诉该lib您希望数据不被转换为Date -objects.因此，您可以更好地控制如何将数据打印到x轴上.此外，您可以使用xLabelFormat根据需要实际打印数据.在此示例中，相应的回调函数会记住最后一个currentYear -Number，以便此数字可以增加下一个数字.
Although the most interesting part are parseTime and xLabelFormat. By setting parseTime false you tell this lib that you want the data not to be transformed into Date-objects. So you have more control of how to print the data onto the x-axis. Furthermore you can use xLabelFormat to actually print the data as you wish. In this examples the corresponding callback-function remembers the last currentYear-Number so that this number can be incremented by the next number.
function getData(sets) {
var result = [];
sets.forEach(function(set) {
result.push({
y: set.year.toString(),
a: set.Initial,
b: set.Initial + set.gain
});
});
return result;
}
var data = getData([{
Initial: 100,
gain: 10,
year: 1
},
{
Initial: 100,
gain: 25,
year: 2
},
{
Initial: 200,
gain: 20,
year: 1
},
{
Initial: 1200,
gain: 180,
year: 1
},
{
Initial: 1200,
gain: 720,
year: 3
},
]),
config = {
data: data,
xkey: 'y',
parseTime: false,
xLabelFormat: function(y) {
this.currentYear = this.currentYear ? (+this.currentYear) + (+y.label) : y.label;
return this.currentYear;
},
ykeys: ['a', 'b'],
labels: ['Total Income', 'Total Outcome'],
fillOpacity: 0.6,
hideHover: 'auto',
behaveLikeLine: true,
resize: true,
pointFillColors: ['#ffffff'],
pointStrokeColors: ['black'],
lineColors: ['gray', 'red']
};
config.element = 'area-chart';
Morris.Area(config);
#area-chart{
min-height: 250px;
}

<meta charset=utf-8 />

P.s.
实际上，我已经制作了一个函数(getData)以正确的格式构建data，以使其与图表配置不冲突.因此，当您想更改图表配置时，还必须更改getData.
P.s.
I actually have made a function (getData) to build the data in the right format so that it does not conflict with the chart-configuration. So when you want to change the chart-config you have to change getData as well.
我还提供了小提琴来展示如何您仍然可以通过调整大小事件来放大此莫里斯图表.在此示例中，放大时该图表将分为两个图表.
I have also provided a fiddle to show of how you can still zoom into this morris-chart by taking advantage of resize-events. In this example the chart will split up into two charts when you zoom in.
