Steps to Reproduce
Create a time series where the data are not evenly distributed.
var dom = document.getElementById('chart-container');
var myChart = echarts.init(dom, null, {
renderer: 'canvas',
useDirtyRect: false
});
var app = {};
var option;
let base = +new Date(1988, 9, 3);
let oneDay = 24 * 3600 * 1000;
let tenDay = 24 * 3600 * 1000 * 10;
let data = [[base, Math.random() * 300]];
// add 100 numbers in first half
for (let i = 1; i < 100; i++) {
let now = new Date((base += oneDay));
data.push([+now, Math.round((Math.random() - 0.5) * 20 + data[i - 1][1])]);
}
// add ten numbers in second half
for (let i = 1; i < 10; i++) {
let now = new Date((base += tenDay));
data.push([+now, Math.round((Math.random() - 0.5) * 20 + data[i - 1][1])]);
}
// data now not evenly distributed
option = {
tooltip: {
trigger: 'axis',
position: function (pt) {
return [pt[0], '10%'];
}
},
title: {
left: 'center',
text: 'Large Ara Chart'
},
toolbox: {
feature: {
dataZoom: {
yAxisIndex: 'none'
},
restore: {},
saveAsImage: {}
}
},
dataZoom: [
{
type: 'inside',
start: 0,
end: 100
},
{
start: 0,
end: 100
}
],
xAxis: {
type: 'time',
boundaryGap: false
},
yAxis: {
type: 'value',
boundaryGap: [0, '100%']
},
series: [
{
name: 'Fake Data',
type: 'line',
smooth: false,
symbol: 'none',
areaStyle: {},
data: data
}
]
};
if (option && typeof option === 'object') {
myChart.setOption(option);
}
window.addEventListener('resize', myChart.resize);
Example: https://codepen.io/s3cp/pen/VwQLVzp
Current Behavior
The dataZoom area shows the data by index, not by time.
Expected Behavior
For the dataZoom area to show the data by time.
Environment
- OS: All
- Browser: All
- Framework: None.
Any additional comments?

The dataZoom area is full width, but the peaks do not line up with the actual graph.
