meanwhile I've been looking for hours for an php barchart module which not only displays bars but also the variance of the corresponding values in form of a little dash above the bars?
I found this entry in stackoverflow: https://stackoverflow.com/questions/110839/best-graph-and-diagram-toolset-for-php - but it did not help
At the moment I'm using the jpgraph_bar.php module of jpgprah: http://jpgraph.net/features/src/show-example.php?target=new_bar3.php
However, it did not support variance information. The feature of the error plot, also listed in the jpgraph repository, would be fine to be in displayed in the barchart: http://jpgraph.net/features/gallery.php#error1
Any ideas where to look at or how can I merge this modules?
EDIT:
Here is an example what I'm looking for: http://www.graphpad.com/prism/tutorials/data_entry/Barchart.gif.

Try the google chart api
I'm not sure they can do what you want, but they are very simple to use and with a good costumization..
You can choose between many kind of chart (Pie, Line, Column, Area, Tree, Controls and more)..
EDIT
After rapid look, seems that this apis supports variance :)
