Javascript 理解百度的“treemap.data.label.formatter”;埃切特酒店
在ECharts for的文档中,其解释如下:Javascript 理解百度的“treemap.data.label.formatter”;埃切特酒店,javascript,charts,echarts,Javascript,Charts,Echarts,在ECharts for的文档中,其解释如下: {@xxx}: the value of a dimension named'xxx', for example,{@product}refers the value of'product'` dimension。 data: [ { name: 'Region1', children: [ {
{@xxx}: the value of a dimension named'xxx', for example,{@product}refers the value of'product'` dimension。
data: [
{
name: 'Region1',
children: [
{
name: 'Region1-Country1',
// Option 1; I can make this work by using `formatter: '{b} brand count => {@[1]}'`
value: [800, 8], //here, '1000' is $ spend and '8' is brand count
// Option 2
value: {'brand':8, 'value':800},
// Option 3
brand: 8,
label: {
show: true,
formatter: '{b} brand count => {@??}' // WHAT should I use after '@'?
},
children: [
{ name: 'Region1-Country1-Brand1', value: 200 },
{ name: 'Region1-Country1-Brand2', value: 500 },
]
},
{
name: 'Region1-Country2',
value: 500,
children: [
{ name: 'Region1-Country2-Brand1', value: 100 },
{ name: 'Region1-Country2-Brand2', value: 200 },
{ name: 'Region1-Country2-Brand3', value: 200 },
]
},
]
},
]
假设我有如下数据:
{@xxx}: the value of a dimension named'xxx', for example,{@product}refers the value of'product'` dimension。
data: [
{
name: 'Region1',
children: [
{
name: 'Region1-Country1',
// Option 1; I can make this work by using `formatter: '{b} brand count => {@[1]}'`
value: [800, 8], //here, '1000' is $ spend and '8' is brand count
// Option 2
value: {'brand':8, 'value':800},
// Option 3
brand: 8,
label: {
show: true,
formatter: '{b} brand count => {@??}' // WHAT should I use after '@'?
},
children: [
{ name: 'Region1-Country1-Brand1', value: 200 },
{ name: 'Region1-Country1-Brand2', value: 500 },
]
},
{
name: 'Region1-Country2',
value: 500,
children: [
{ name: 'Region1-Country2-Brand1', value: 100 },
{ name: 'Region1-Country2-Brand2', value: 200 },
{ name: 'Region1-Country2-Brand3', value: 200 },
]
},
]
},
]
基于上述文档中的解释,我如何准备
数据
数组,以便使用格式化程序:{b}品牌计数=>{@brand}'
并在绘制的地图中显示Region1-Country1品牌计数=>8
。我想我找到了答案。张贴在这里与社区共享
我们需要在series
中设置维度,而不是series.data
。换句话说,如果我们这样做:
series: [{
name: 'Root',
type: 'treemap',
dimensions: ['value','brand'],
visibleMin: 300,
leafDepth: 2,
levels: [...] // skipped the details for `levels` here
data: [
{
name: 'Region1',
brand: 9,
children: [
{
name: 'Region1-Country1',
value: [1000,8], // we can define dimensions like here: https://ecomfe.github.io/echarts-doc/public/en/option.html#dataset.dimensions
label: {
show: true,
formatter: '{b} brand count => {@brand}',
},
children: [
{ name: 'Region1-Country1-Brand1', value: 200 },
{ name: 'Region1-Country1-Brand2', value: 500 },
]
},
]
},
]
}]
那就行了(我已经测试过了)。我通过阅读ECharts文档的另一部分得出了这个答案
