坐标轴刻度的时间区间长度是给定的（一个季度）我怎么能设定比如只显示三个坐标轴刻度么？或者自适应均匀些？-灵析社区
777七月类似 （[https://www.visactor.io/vchart/demo/line-chart/multi-line](https://link.segmentfault.com/?enc=x71MtXwNuP002BIm5pD2Lg%3D%3D.PsH3hiPLZK5qnBmS264wosb1K55jinxyT9rv%2BUnElgYCD6bZlFkR9MbmI43uft3QYvtScqX%2BRrNJcKM9dxwD1Q%3D%3D)）这样的折线图：  坐标轴时间区间长度给定的情况下，该怎么设置坐标轴刻度的显示数量？例如我想只显示三个坐标轴刻度，或者自适应刻度数量。
脑袋困掉惹解决方案：
在VChart中，共有linear、band、time、log4种坐标轴类型。对于每种坐标轴，只需要设置tick.tickCount=3，或者tick.forceTickCount=3
即可指定坐标轴刻度的数量。

当未指定tickCount时，会采用自适应tick数量，自动寻找能够使所有轴标签都不重叠的最大tick数量。

代码参考：
const spec = {
type: 'line',
data: {
values: latestData,
},
xField: 'country',
yField: 'value',
seriesField: 'name',
axes: [
{
orient: 'left',
domainLine: { visible: false },
tick: { visible: false },
label: {
style: {
fill: 'rgb(162, 162, 162)'
}
},
grid: {
style: {
lineDash: [0],
stroke: 'rgb(231, 231, 231)'
}
}
},
{
orient: 'bottom',
domainLine: { visible: true, style: { stroke: '#000' } },
tick: {
style: { stroke: '#000' }
tickCount: 3,
}
}
],
};
