Cluster bar chart overlapping with date xaxis

See original GitHub issue

Version

4.1.0-release

Steps to reproduce

when using adaptive barWidth with a clustered bar chart and date x-axis, bars of 2 adjacent clusters can overlap when playing with the area zoom slider.

You can find below an example to reproduce the problem on https://echarts.apache.org/examples/en/editor.html

Once loaded, you’ll have 6 groups of 4 bars each. 2.Start zooming-in until you have 1 group and then zoom out/in.
You can notice that the groups overlaps.
