Changing dot's color in ChartJS plugin

Hello, I making Data Analysis web page using and ChartJS plugin

The function I want to make is to change single dot in line graph.

My graph’s X-axis value is time (mm/dd/yyyy HH:MM), and Y-axis value is cost($).

I want to make single dot’s color being changed (y-axis value) when I clicked matching x-axis value.

Can I do this with ChartJS’s intrinsic function or should I use HTML??
