Forecasting - Line chart

I want to create a forecasting visual that looks like a line chart. my X axis will have Month year and Y axis will have employee count.

I want to forecast the number of employees in the consecutive month years ( September 2018 - Dec 2018) based on 2 measures that I have :  Hiring rate in 2018 and Termination rate in 2018. So my chart should be able to predict the count of employees for the next few months based on the hiring rate and termination rate i have as of now.

Is there any sort of custom visual that supports this? Thank You!
