Question: how to disable vertical line on hover

[unlight]

When I moving mouse along Y axis.
In addition to tooltip, vertical line is showing.
How to disable it?

Use css:

.c3-event-rects { display: none }

This is an incorrect solution. Because in this way you'll hide entire events layer.
If you need to disable only vertical bar, use .c3-xgrid-focus class:

.c3-xgrid-focus { display: none; }
