[Solved]-Angular 5 is not rendering the component until click or hover anywhere-Highcharts

it might be an incorrect pipe operator. i had a similar issue with angular 11 and mat-table. the rows wouldn't show up until i hovered over them. my issue was that i was using an invalid pipe operator on one of the columns. i was using a decimal pipe on a string column. once i corrected that it works perfectly.

you should call changedetectorref detectchanges()
