Access canvas object from parents

[HiepVu511]

Hi,
Sorry if this is a noob question.
Basically, I want to add gradient background color to a bar chart which receive data from a parent component, so I guess I have to pass the backgroundColor property from parent component too.
So how can I access the canvas object of a chart from the parent component?

You can access the canvas over the refs . Inside your chart component you can access it over this.$refs.canvas.
