Ogive Graph (cumulative frequency polygon) - one variable analysis
You can make easily an ogive graph (cumulative frequency polygon) in GeoGebra when you start with a dataset. You use the the button 'One Variable Analysis' of the spreadsheet.
But if you just have classes with their absolute frequencies you don't have the option to work with cumulative frequencies. You can make with the same button a histogram and a frequency polygon by using the centers of the classes and the absolute frequencies. But you can't make an ogive graph. Can this option also be implemented?
