我使用Chart.js为使用Ionic2和Angular2的混合应用程序创建堆叠条形图。我无法获取图形中背景颜色或填充条的颜色以更改。我已经使用了在chart.js documentation上给出的每个配置/示例,并且我总是获取默认的红色和蓝色默认(?)颜色。Chart.js Ionic 2 Angular2:条形图的背景颜色不变
以下是我有:
barChartOptions:any = {
responsive: true,
scales: {
xAxes: [{
categoryPercentage: 0.6,
barPercentage: 1.0,
stacked: true,
ticks: {
beginAtZero: true
},
gridLines: {
color: "rgba(255,255,255,1.0)",
zeroLineColor: "rgba(254,254,254, 1.0)"
}
}],
yAxes: [{
display: false,
ticks: {
beginAtZero: true
}
}]
},
legend: {
display: false,
}
};
barChartLabels:string[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
barChartType:string = 'bar';
barChartLegend:boolean = false;;
barChartData:any[] = [
{
fillColor:'rgba(255, 99, 132, 0.2)',
borderColor: "rgba(10,150,132,1)",
borderWidth: 5,
data: [65, 59, 80, 81, 56, 55, 40],
},
{
backgroundColor: '#61ae37',
data : [190,150,125,185,150,135,175]
}
];
的问题是fillColor
或barChartData对象的backgroundColor
领域。
,我已经从文档中尝试过其他CONFIGS是:
data: [12, 19, 3, 5, 2, 3],
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
我也不能得到边框的颜色改变,即使我可以得到边框宽度改变。
我也试着改变矩形配置。没有收益。
我复制的原代码是这样的:
var data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
backgroundColor: "rgba(255,99,132,0.2)",
borderColor: "rgba(255,99,132,1)",
borderWidth: 1,
hoverBackgroundColor: "rgba(255,99,132,0.4)",
hoverBorderColor: "rgba(255,99,132,1)",
data: [65, 59, 80, 81, 56, 55, 40],
}
]
};
我最好的猜测是,有是优先于我的配置一些默认配置。任何帮助将不胜感激。
这适用于条形图。你知道如何改变甜甜圈图的颜色吗? – Venkat
