Hello Community,
is there a possibility to generate ROC curves in consistent way with regard to the color? By sequentially executing ROC-processes RapidMiner generates the following ROC curves where e.g. the SVM curve has once a green color and once a red color. This looks very strange with respect to subsequent analytical comparisons and dicussions.

Thank you for your help!

Hi,I think the reason is a different execution order of operators in both cases. If you go inside the Compare ROC operator and press one of the icons in the top right corner of the process it will show the execution order of operators. Make sure that the order is the same for both processes and this should align the colors.More information on execution order can be found here:Hope this helps,

thank you for your answer that makes sense. You mean the order of the model execution within Compare ROC, right?
