问题标题
VChart 如何避免饼图扇区的hover时描边被遮挡?
问题描述
配置了饼图扇区的hover描边,但是会被其他扇区遮挡
解决方案
可以调整元素在hover时的层级,这样hover元素始终展示在其他扇区上面,就可以避免描边被遮挡的问题
pie: {
state: {
hover: {
stroke: 'black',
lineWidth: 4,
zIndex: 1
}
}
},
代码示例
const spec = {
type: 'pie',
data: [
{
id: 'id0',
values: [
{ type: 'oxygen', value: '46.60' },
{ type: 'silicon', value: '27.72' },
{ type: 'aluminum', value: '8.13' },
{ type: 'iron', value: '5' },
{ type: 'calcium', value: '3.63' },
{ type: 'sodium', value: '2.83' },
{ type: 'potassium', value: '2.59' },
{ type: 'others', value: '3.5' }
]
}
],
outerRadius: 0.8,
valueField: 'value',
categoryField: 'type',
title: {
visible: true,
text: 'Statistics of Surface Element Content'
},
legends: {
visible: true,
orient: 'left'
},
label: {
visible: true
},
pie: {
state: {
hover: {
stroke: 'black',
lineWidth: 4,
zIndex: 1
}
}
},
tooltip: {
mark: {
content: [
{
key: datum => datum['type'],
value: datum => datum['value'] + '%'
}
]
}
}
};
const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();
// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;
