Amcharts Covid-chart slight modification [Javascript]

Hello there! I like very much Covid-chart by [login to view URL], BUT I want to use it not for covid , but for my personal case. I need some slight modifications. It is Javascript & It is static (not something dynamic) that runs using the browser, locally from a directory. I provide all the code, in working state. I want the functionallity to be preserved as is (no modification to functionallity & and the way the numbers are displayed). Basically, the chart displays 3 numbers/ per country/ per date, in map mode and line chart (please check it out here: [login to view URL]) I only need three specific modifications: 1. To be added 3 more data series (3 are existing now) and work exactly like the native three series. 2. To give the 6 resulting series my own names. 3. One of the series ("Deaths" at the demo) to perform "add" function over the other 6 numbers of each country (now it performs "-" function) Thank you!
