how to add dots (addPoint) to the Highcharts double Y-axis table (multiple axes)?

I want to make two curves of temperature and humidity in one table, each using a separate Y axis; the X axis is the date. How to add some through JavaScript?

I will not specify which curve to add (temperature or humidity). You cannot set the Abscissa of this point after you specify a curve.

I hope God"s advice, thank you!
