one variable analysis tool: Editing options for classes and histogram disappearing

I'm teaching a statistics class and my students and I have a problem with the Geogebra 6 app.


In the older version of Geogebra you could choose if the spreadsheet cells used with the one variable analysis tool are data, data & frequences, classes & frequences and so on.


In the new version this is not possible and I can't find a way to make the program understand that the column of cells I have written down is frequency values, not data.


Also if I try to edit the classes by myself, the whole histogram just disappears and so does the editing window for lower limit and the class interval . I'm just given a blank screen. This seems to be some kind of bug because I can make the axis reappear by changing the language setting.


Any ideas on what is going on and how to fix this problem?

Any random column of cells with values will do, but let's say I am trying to make a histogram based on how tall a group of people are. The lower limit being 160 cm for example, with class interval of 10 cm.


In previous Geogebra 5 when I start the one variable analysis the program opens a window with the settings option button and a grabbing tool for the cells. I usually have only the frequencies written down and choose "data and frequency". In the same window I can set the lower limit and the class interval.


However now in Geogebra 6 this window does not appear. The cells are automatically taken as data values and changing the class limit to 160 will cause the bug. It seems to me that the diagram is drawn somehow out of the window boundaries. Sadly I can't fix the settings so that it would reappear.


However I can circumvent this problem by actually writing down the class limits on a second column. This way the program automatically understands that the first is classes and second column is the frequencies.

Yes, that's the intended workflow in GeoGebra 6

The .ggb file you posted doesn't seem to relate to that - please explain more or post the .ggb file
