Dear All
This is a satisfy my curiosity.
Does anyone know of a statistical, mathematical or graphical
package that will draw a true histogram without major
programming?
I know SPSS, Excel, Minitab and other do a histogram by dividing
the data range into equal length segments and then drawing a
barchart with the frequency of each segment along y Axis. I am not
looking for this.
I am looking for something that will, without the cludge above, plot
a graph where the area of the segment is proportional to the
frequency within the segment. That is you do not need to have the
segments range equal in each case.
I have once needed to do this. At the time I looked at Sigmaplot,
asked a colleague about Matlab and tried in SPlus.
In the end I did a cludge in Excel. I would guess that I could
programme SPlus to do the same cludge. That is to trace the
outline of the graph via a line graph but anyone come across
anything sensible.
Thanks for your responses.
Jean
