If you have recently applied the OBIEE 22.214.171.124.2. BP1 update and were using customized skins or folders, you may have found that your charts / graphs do not work any more after the upgrade.
The reason behind this is, that the upgrade process does not touch the customized folders and skins.
Getting the charts and graphs back into working condition should be fairly simple - just copy the necessary files into your customized folders and you should be nearly set and fixed.
Which ones are there and where to put them?
Still does not work - check if you cleared your browser cache to make them reload
