我目前正在重写使用AngularJS和google-charts的旧版应用程序,现在可以使用Angular和AmCharts。
对于旧应用程序中的图表,用于呈现图表的数据为'Sales'OR'Units'。但是对于工具提示,我们希望同时显示“销售”和“单位”的值。这是我们其中一个图表的工具提示,其中显示了特定产品的销售:Legacy chart tooltip
我能够使用折线图复制它,但是无法使用饼形图。
代码i用于折线图的工具提示显示“销售”和“单位”:
...
chart.data = this.data
function createDollarAxis(field, name, unit, opposite) {
let series = chart.series.push(new am4charts.LineSeries());
series.dataFields.valueY = field;
series.dataFields.valueX = unit;
series.dataFields.dateX = 'date';
series.strokeWidth = 2;
series.name = name;
series.tensionX = 0.8;
series.tooltipHTML = `
<div style="text-align:center">
<p style="border-bottom:1px solid; margin:0px 10px 10px">
{date}
</p>
<strong>{name}</strong>
</br>
<p style="display:inline;margin:0">
Units: {valueX}
</p>
<div style="display:inline-block;width:10px"></div>
<p style="display:inline;margin:0">
Sales: {valueY}
</p>
</div>
`
...
}
createDollarAxis('name', 'dollars', 'units', false);
即使图表仅直观地显示销售数据,我也可以使用'valueX'数据字段来获取要添加到我的工具提示中的单位值。
除了“值”或“类别”外,饼图似乎没有其他可用于此目的的dataFields。目前,对于我的饼图,我有一些类似的东西:
let chart = am4core.create(this.chartid, am4charts.PieChart);
chart.data = this.data;
function createPieSlice(name: string, data: string, data2: string) {
let pieSeries = chart.series.push(new am4charts.PieSeries());
pieSeries.dataFields.value = data;
pieSeries.dataFields.category = name;
...
pieSeries.slices.template.tooltipHTML = `
<div style="text-align:left;margin:5px;">
<strong style="color:white;">{category} - {value.percent.formatNumber('#.0')}</strong>
<br/>
<p style="display:inline;margin:0;color:white;">
Gross Dollars: $ {value.value.formatNumber('###,###,###.00')}
</p>
<br/>
<p style="display:inline;margin:0;color:white;">
Gross Units: { <need 'units' data here> }
</p>
</div>
`
...
}
// create slices with above function
createPieSlice('category', 'sales', 'units');
是否可以将其他dataField(或其他类型)添加到PieSeries?任何信息将不胜感激。
我正在使用AmCharts 4.7.17和Angular 8.0.0。
function createPieSlice(name: string, data:string) {
// Create slices
let pieSeries = chart.series.push(new am4charts.PieSeries());
pieSeries.dataFields.value = data;
pieSeries.dataFields.category = name;
pieSeries.ticks.template.disabled = true;
pieSeries.alignLabels = false;
// Add inner labels to pie slices
pieSeries.labels.template.text = `{value.percent.formatNumber('#.0')}%`;
pieSeries.labels.template.radius = am4core.percent(-25);
pieSeries.labels.template.fill = am4core.color('white');
// These functions are here so the inner labels don't show whenever the slice is less than 5 percent
pieSeries.labels.template.adapter.add('radius', function(radius, target) {
if (target.dataItem && (target.dataItem.values.value.percent < 5)) {
target.dataItem.label.text = '';
return 0;
}
return radius;
});
pieSeries.labels.template.adapter.add('fill', function(color, target) {
if (target.dataItem && (target.dataItem.values.value.percent < 5)) {
return am4core.color('white');
}
return color;
});
// Custom Tooltip styling
pieSeries.slices.template.tooltipHTML = `
<div style="text-align:left;margin:5px;">
<strong style="color:white;">{category} - {value.percent.formatNumber('#.0')}% </strong>
<br/>
<p style="display:inline;margin:0;color:white;">
Gross Dollars: $ {value.value.formatNumber('###,###,###.00')}
</p>
<br/>
<p style="display:inline;margin:0;color:white;">
Gross Units: {units} //You just need to add the key. Doh!
</p>
</div>
`
pieSeries.tooltip.getFillFromObject = false;
pieSeries.tooltip.background.fill = am4core.color('black');
pieSeries.tooltip.pointerOrientation = 'vertical';
// Adds a border around each slice
pieSeries.slices.template.stroke = am4core.color('#fff')
pieSeries.slices.template.strokeWidth = 0.5;
pieSeries.slices.template.strokeOpacity = 1;
pieSeries.slices.template
.cursorOverStyle = [
{
'property': 'cursor',
'value': 'pointer'
}
];
// Center label with total
let label = pieSeries.createChild(am4core.Label);
label.text = `$[BOLD]{values.value.sum.formatNumber('###,###,###.00')}`;
label.horizontalCenter = 'middle';
label.verticalCenter = 'middle';
label.fontSize = 15;
}
createPieSlice('retailer', 'sales');
...
因此,您需要为工具提示做的就是添加要显示的任何数据值的键,因此,由于我的数据看起来像{ retailer: 'blah', sales: 999, units: 999 }
,因此您需要做的就是在标签/中添加'{units}'/工具提示。
