Bar chart values are showing on the left side and not above the bar line if moves to vertical

## What did you do?

I've implemented bar chart in my current application.

## What did you expect to happen?

I want to show the values of bar chart in vertical form not in horizontal form.

## What happened instead?

I put the valueLabelAngle = 90 and the values moved to vertical but its not showing above the bar and showing on the left side.

## Demo Project

I'm attaching a screenshot please look into it and let me know how can I fix it. Thanks!

Reproduce the issue in a small iOS bar-chart example using valueLabelAngle = 90 and compare the label position with the attached screenshot. No source file, entry point, or test is named, so first locate the bar-chart value-label positioning code and existing related tests. Done means vertically oriented values render above their corresponding bars rather than to the left.
