[Feature] Add more alignment values to chart title, xAxes and yAxes

[jamesbarrett95]

Bug []
Feature Request [x]

Expected Behavior

• Documentation for positioning a title in Chart.js are: top, left, right, bottom. I believe the option for adding two values such a top left should be added.
• User should have the option to align xAxes and yAxes values to start, middle or end.

An example of this expected behavior is shown in the following image:

As you can see - the chart title is aligned top left, yAxes is aligned at the start and the xAxes is aligned at the start.

Current Behavior

I'm only able to align chart titles to the middle. For example:

Possible Solution

• xAxes/yAxes - Add an align property to the scaleLabel object. For example: scaleLabel: { align: 'start' }
• Title: - Add an align property to the title object. For example: title: { align: 'top left' }

Context

For me personally, I want to align many of my chart and yAxes titles to the top left as viewers tend to absorb visualisations in a zigzag direction. So by starting at the top left, the user will find the chart title and yAxes title immediately.

Scale title options exist in v2.9.x. Title alignment options added in #6908

I would like to know if this option has already been implemented for version two of chartjs?
