Update dependency chart.js to ~2.9.0 [SECURITY]

[renovate]

This PR contains the following updates:

Package	Change	Age	Adoption	Passing	Confidence
chart.js (source)	~2.6.0 -> ~2.9.0

GitHub Vulnerability Alerts

CVE-2020-7746

This affects the package chart.js before 2.9.4. The options parameter is not properly sanitized when it is processed. When the options are processed, the existing options (or the defaults options) are deeply merged with provided options. However, during this operation, the keys of the object being set are not checked, leading to a prototype pollution.

v2.7.0: Version 2.7.0

Compare Source

Version 2.7 brings better stability, and powerful new features to Chart.js. The bubble chart options are now completely scriptable. This means that you can pass a function to a bubble chart dataset property and have the function be called as needed. This simplifies array properties, and allows quick and easy rendering changes based on data values. Check out the sample for details. If these options prove useful, they can be extended to other chart types in the future.

Building off the time scale rewrite in version 2.6, the time scale now supports options for configuring how labels generate ticks, how interpolation between the points is handled and the scale boundary strategy. Users can now configure ticks to be generated for each label, or be determined automatically from the data limits. Users can also change how ticks are distributed along the axis] to make non-linear time axes. Check out the sample for details.
