scatter plot doesn't work any more


I've analysed a dataset with 800.000 rows and 50 columns with an PCA analysis and showed the result on an Scatterplot. This worked two to three times very well. Sinc two days it wont work any more on new Scatterplots. Older ones continue working but new one don't. Even if I use them on the same Database. The settings were identical.


Any ideas anyone ?


Best regards
