Expected Behavior

Have the option to skip NO border stroke of a bar from bar chart. (option borderSkipped)

Current Behavior

borderSkipped can only be set to 'bottom', 'left', 'top' or 'right'.
For stacked (horizontal) bar charts, skipping a border creates a "hole" at the bar if the previous dataset is transparent (for example when creating a custom Gantt chart):

Possible Solution

Add value 'none', 'false' or similar to the borderSkipped option

Context

I created a Gantt chart (horizontal bar chart with four datasets (two for data, two for offset values)), which works fine so far (see picture above).

The first data is the blue bar, the second data is a bar without background color, but a red border (to show deviations of the two values).

I have two X axes (one for data & offset each) and one Y axis.

The problem is ChartJS' barSkipped option: It removes one border stroke (bottom, left, top or right), but I need to show ALL strokes for this use case.

Environment

• Chart.js version: 2.7.2
• Browser name and version: all
