Chartjs-Chart js how do I only show just the low/high dots on line chart?

I was able to find a solution in case this helps anyone else out.

1. as i generate my xData and yData from api, i then grab min/max value from array
2. then i loop thru yData array and pull out the index of the min/max
3. as i’m initializing line chart, i used a function for pointRadius in the datasets that sets the dot to 10 if it’s low or high, if not set it to 0 so it doesn’t show
