Re: How can i show different scale (site, region, country) for one expression (average) ?
Sorry, I was maybe confused on my topic....I don't want to do a Histogram but a Barplot. I don't search to show the frequencies and the repartition but the level of a composant at different geographic levels.
I know how to do a histogram and i looked the two links you shown me (and thank to give them to me so i will never search for them again if i have a problem) but it's not exacly my goal.
What I want to have is the average for a site and the average for the district where is the site and again with the region.
i have a sample of my dataset to show
if i select the sample point "10086.PS1.0.1" and i want to show the different levels of the componant "D"
i will have one bar: = value of "D" for "10086.PS1.0.1" = 11
one bar = avg (10086) = (11+7.6)/2 = 9.3
one bar = avg ("lormont") = (11+7.6)/2 = 9.3
one bar = avg ("33") = 16.83
and finally one bar = avg ("Aquitaine") = 34.2
I hope not missing something and not being bothering you?
