Hello,
I am currently working on graphics in jaspersoft Studio and would like to know if it was possible to display the value of the bars vertically above this one ?
Currently all my values ​​are displayed horizontally

Not sure what charting solution is being used but if you were to use HTML5 Charts then you can set a property:

plotOptions.series.dataLabels.rotation (with a rotation value in degrees)

to rotate the data labels. Here is a fiddle sample using this api:
