I require a Java command line program that creates a Timeline chart from an Excel File and produces a PNG file. The program should use Java 8.
The java program must be custom written (no charting/graphing libraries allowed).
The java program should take the following parameters:

Java -jar [login to view URL] “My Title” 600 300 blue 1990 2010 2 [login to view URL]

Width: is the width of the PNG to be created
Height: is the height of the PNG to be created.
Color: is the color of the lines to be created
Startyear: is the first year to be displayed
StopYear:is the last year to be displayed
Yearincrement: is the year increment to be used (i.e. if 10 then 1900, 1910, 1920, etc)
