我使用Chart.js爲使用Ionic2和Angular2的混合應用程序創建堆疊條形圖。我無法獲取圖形中背景顏色或填充條的顏色以更改。我已經使用了在chart.js documentation上給出的每個配置/示例,並且我總是獲取默認的紅色和藍色默認(?)顏色。Chart.js Ionic 2 Angular2:條形圖的背景顏色不變
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]
}
];
的問題是fillColor
或barChartData對象的backgroundColor
領域。
,我已經從文檔中嘗試過其他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
我也不能得到邊框的顏色改變,即使我可以得到邊框寬度改變。
我也試着改變矩形配置。沒有收益。
我複製的原代碼是這樣的:
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],
}
]
};
我最好的猜測是,有是優先於我的配置一些默認配置。任何幫助將不勝感激。
這適用於條形圖。你知道如何改變甜甜圈圖的顏色嗎? – Venkat
