您可以使用自定义标签格式化程序来显示时间值而不是数字。
times = [
3:00 am,
7:00 am,
11:00 am,
3:00 pm,
7:00 pm,
11:00 pm ,
]
public bubbleChartOptions:ChartOptions = {
响应式:true,
比例尺:{
xAxes:[{ticks:{min:0, max:30,}}],
y轴:[{
ticks:{
min:0,max:5,
callback:value => this.times [value]
}
}]
}
};
公共泡沫图表数据:ChartDataSets [] = [
{
数据:[
{x:7,y:0,r:8},
{x:10,y:1,r:10},
{x:15,y:2,r:15},
{x:26,y:3,r:23},
],
标签:'Series A',
},
];

I came across Bubble Chart
(latest addition) in ng2-charts. I am trying to show data according to the time in Y-axis and values in X-axis.
My Data is like x:[10,35,60] and y:["7.00 AM"] and r will the same value of x. Basically I want to show multiple data for one date but the sample dataset given is different from my dataset. Can you help me out? and one more thing, I want to hide r
from tooltip.
Sample code
HTML
<div style="display: block">
<canvas baseChart [datasets]="bubbleChartData" [options]="bubbleChartOptions"
[colors]="bubbleChartColors" [legend]="bubbleChartLegend" [chartType]="bubbleChartType"
(chartHover)="chartHovered($event)" (chartClick)="chartClicked($event)"></canvas>
</div>
TS
public bubbleChartType: ChartType = 'bubble';
public bubbleChartLegend = true;
public bubbleChartData: ChartDataSets[] = [
{
data: [
{ x: 10, y: 10, r: 10 },
{ x: 15, y: 5, r: 15 },
{ x: 26, y: 12, r: 23 },
{ x: 7, y: 8, r: 8 },
],
label: 'Series A',
backgroundColor: 'green',
borderColor: 'blue',
hoverBackgroundColor: 'purple',
hoverBorderColor: 'red',
},
];
This Y axis supports only numeric numbers but I want to bind time like 11:15 AM
What I Want
解决方案
You can use a custom label formatter to display time values instead of numbers.
times = [
"3:00 am",
"7:00 am",
"11:00 am",
"3:00 pm",
"7:00 pm",
"11:00 pm",
]
public bubbleChartOptions: ChartOptions = {
responsive: true,
scales: {
xAxes: [{ ticks: { min: 0, max: 30, } }],
yAxes: [{
ticks: {
min: 0, max: 5,
callback: value => this.times[value]
}
}]
}
};
public bubbleChartData: ChartDataSets[] = [
{
data: [
{ x: 7, y: 0, r: 8 },
{ x: 10, y: 1, r: 10 },
{ x: 15, y: 2, r: 15 },
{ x: 26, y: 3, r: 23 },
],
label: 'Series A',
},
];
