Scale the axis in a histogram

[Matthias Enichlmayr]

Hi,
I am trying to scale the x-axis of a histogram, I tried scale, xscale and xscale(range(0 26)) for instance. It does not work.
Do you have any idea?
Many thanks

I cannot replicate that behaviour:

sysuse auto, clear

// histogram without rescaling
hist price, name(without)

// histogram with rescaling
hist price, xscale(range(0 20000)) name(rescaled)

Can you give us more details; "does not work" isn't very informative.

[Matthias Enichlmayr]

sure, sorry
the type of the variable is float. I tried the hist command without rescaling

hist age_car

--> The x-axis ranged from 0 to 2000

Then I applied your command

hist age_of_the_car, xscale(range(0 26)) --> The x-axis still ranged from 0 to 2000 Is this enough information or do you need additional input? Kind regards

Stata does not like it when you try and restrict the range of an axis to less than the range of the data; what do you mean by "scale the axis"? you can, after all, just divide the values of your variable by 100

hist age_of_the_car, xscale(range(0 26)) --> The x-axis still ranged from 0 to 2000 Is this enough information or do you need additional input? Kind regards

You may also consider having a look at this article, where this behaviour is neatly explained.

[Matthias Enichlmayr]

yes Rich Goldstein, thats the point. Even thoug I have large outlier with very high values, I only want stata to show me the x-axis up to a certain point (in my example 26), since the majority of the data are in this area...

You'll then have to restrict the histogram adding an "if":

hist age_of_the_car if age_of_the_car<=26, xscale(range(0 26))

Hope this helps!

I am having the same trouble!!!! I don't want to use the 'if' statement since this affects the y axis! Any other ideas!?

barysaus: You asked this question in http://www.statalist.org/forums/foru...s-on-histogram and there was an answer.

Sorry Nick! I am new and did not realize you answered yesterday! Thanks
