这是我第一次使用Chart Js,我设法让它显示在我的页面上,但键"label"、"backgroundColor"、"borderColor"one_answers"borderWidth"不会显示。键"标签"one_answers"数据"工作得很好,因为我可以看到图表中的标签和条形图。我试着将非显示键分配给变量,比如"标签"one_answers"数据",看看它是否能以这种方式工作,但没有成功。我还试着传递十六进制颜色和常规颜色名称,如红色、蓝色等,但也不起作用。如果有人能提供一些帮助,我们将不胜感激,谢谢!
'use strict';
import React, { Component } from 'react';
var Chart = require("react-chartjs").Bar;
class BarChart extends Component {
capitalize(name) {
return name.charAt(0).toUpperCase() + name.slice(1);
}
render() {
var pokeLabels = this.props.stats.map((label) => {
return this.capitalize(label.stat.name)
})
var pokeDataSet = this.props.stats.map((set) => {
return set.base_stat
})
console.log(this.props.stats);
var data = {
labels: pokeLabels,
datasets: [
{
label: 'Pokemon Stats',
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1,
data: pokeDataSet
}
]
}
return (
<div className='row'>
<div className='col-xs-12 col-sm-offset-3 col-xs-offset-0'>
<Chart data={data} width="600" height="250" redraw />
</div>
</div>
);
}
}
export default BarChart;
所以我可以通过这样做来获得颜色:
datasets: [
{
label: "My First dataset",
fillColor: ["rgba(0,10,220,0.5)","rgba(220,0,10,0.5)","rgba(220,0,0,0.5)","rgba(120,250,120,0.5)" ],
strokeColor: "rgba(220,220,220,0.8)",
highlightFill: "rgba(220,220,220,0.75)",
highlightStroke: "rgba(220,220,220,1)",
data: pokeDataSet
}
希望这能帮助到有类似问题的人!
背景颜色将更改条形图的颜色。
所以,你可以给不同的酒吧不同的颜色。
datasets: [
{
label: 'My First dataset',
backgroundColor: ['rgba(0,10,220,0.5)', 'rgba(220,0,10,0.5)'],
borderColor: 'rgba(0,0,0,1)',
data: pokeDataSet,
},
],
