Expanding my graph program

My graph program is good for quickly drawing up to four series on a single chart, with automatic scaling. I can also use functions in the arguments.  So I don't need to create the series before charting it, like one has to in Excel.  I can just type in 'YOY USIP', for example, and it does the calc for me.   But I wanted the ability to draw several charts on one page, either with the same time scale or different ones—for example, a chart at the top showing a long-term relationship with shorter periods below.  It will allow up to six charts, with different configurations.  Writing the codes was fairly difficult!  It still needs some tweaking but as you can see, works quite well.  I'll improve it incrementally as I go on.  The Elon Musk method.
