I got the workaround that is, set the 'bar' Chart Type Metric as the first one, then all the chart series will aligned with the first one. but this only can align the head but the bar char tail sometimes still missed.
the last date point is missed sometimes in the dashboard.

Hey @guanghaofan, which version of Kibana are you running? Also, can you export the problematic Visualization and attach it here?

My Kibana is 6.2.5-snapshot version

In this char, the last date point is missed in the bar: 2018-05-15, Qty 1426
here is the screen shot

Hey @guanghaofan, which version of Kibana are you running? Also, can you export the problematic Visualization and attach it here?

I think this also happens on version 6.3.0, this is a example that version:
here you can see the leading and the tail are not aligned across the bar chart and the line chart

Another small issue:

the chart type are: bar-line-bar, you can see the two bars are placed partially overlapping.

changing to : bar-bar-line, now this is the normal case!

Hey @guanghaofan these seem like two separate bugs, would you mind creating two separate issues for these here
