Steps to reproduce the behavior:

1. Render multiple ngx-charts-bar-horizontal toghether with different data inside one single page
2. refresh the page (preferabilly multiple times, each time will be slower)

Expected behavior
Multiple charts can be shown in the same page with different data, while also showing xAxis and yAxis. When refreshing page, it should also show properly
