Blinking the datapoint symbol in line chart

[#1]

I need some help to show the symbol in chart should be blinking.

I have one line for daily count of month & another line average of previous month

The requirement is to compare daily count with Average & highlight in different colour on the daily count line with blinking if the diff is more than 10%

I got the the solution for this.We can use if (odd(second(now()),RED(),0).It is working very well with my requirement.
