Ngx-charts: Chart Width Calculation Adjustment - Chrome

Current behavior

We've encountered a bug that manifests itself in chrome when the browser zoom is adjusted. The bug appears to be in the chart width calculation. At certain chart and y-axis widths, the tag will loop on a "1px" width adjustment. This will create a flickering in the chart. A similar bug report (#349) is open for charts with y-axis labels and/or custom axis ticks marks but we are experiencing the behavior in the absence of those attributes.

We're seeing a CPU usage spike of ~10 -15% when the browser encounters the bug.

First time posting, appreciate the patience.

Expected behavior

Chart scales with zoom / width.

Reproduction of the problem

What is the motivation / use case for changing the behavior?

We hope to use ngx-charts in our production app!

Could we explore increasing the unit of adjustment to an integer greater than 1px?

Please tell us about your environment:

• ngx-charts version: 9.0.0

• Angular version: 6.1.7

• Browser: Chrome Version 68.0.3440.106

• Language: TypeScript 2.9.2

+1. We are seeing the same problem on different charts types in dynamically rendered parent containers (flexbox and grid).

It also happens on the Kubernetes Dashboard.

In all this issue you can find an infinite way to reproduce the problem.

The Kubernetes dashboard is a fairly visible project.
Is there room for someone to solve this problem shortly?

There is another issue for the same problem open since spring 2017. 😞
