Hello,
My question is: how can I get a display with the Histogram function, that
is 100% faithful to my data?
With a particular data set I have, the only way I get a fully
faithful display is by tweaking the options of the function.
Here are some details. If I work out the frequencies associated to my data
I see that:
1) the peak of the distribution in the display is at a much higher
value than it should be;
2) there are many more categories in my data than the histogram shows.
In both cases, there seems to be some scaling going on that I do not want
them to happen. All I want is a fully faithful display of my data.
In order to get the histogram I need, by tweaking the options of the
function, as follows,
Histogram[mydata, HistogramCategories -> 10000, HistogramScale -> False];
then the display looks more faithful...
So, how should I use the Histogram function so that I can *always* get
(as simple as that) a 100% faithful display of my data?
Many thanks for any clarification.
