.map(function (item) {
return [item[1], item[0], item[2]*100 || '-'];
});
option = {
tooltip: {
position: 'top'
},
grid: {
height: '50%',
top: '10%'
},
xAxis: {
type: 'category',
data: hours,
splitArea: {
show: true
}
},
yAxis: {
type: 'category',
data: days,
splitArea: {
show: true
}
},
visualMap: {
min: 0,
max: 10,
calculable: true,
orient: 'horizontal',
left: 'center',
bottom: '15%'
},
series: [
{
name: 'Punch Card',
type: 'heatmap',
data: data,
label: {
show: true,
width:30,
overflow:'truncate'
},
emphasis: {
itemStyle: {
shadowBlur: 10,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
};
```
2. Pull the Heatmap view smaller
3. Play around with series[0].label.width property
### Current Behavior
Currently we have to set a fixed width for truncating the value of each cell. This results in the following behaviour:
Either the value is smaller than the width and it is displayed. Or the value is larger than the width. Then ellipsis is displayed.
### Expected Behavior
I would expect that the width can be dynamic so that the value is truncated if there is not enough space and not truncated if there is enough space.
### Environment
```markdown
- OS: Windows
- Browser: Chrome
- Framework: Angular
```

I didn't seem to find a problem when I tried it, was this problem solved?
Is this the expected effect?
