Hi! I need to create a dynamic baseline which is based on the average of the field [transaction.duration.us](http://transaction.duration.us) of the previous month. I have tried to create a runtime field, but the fact that the data is located in seperated docs as histogram data causes trouble for aggregation. I am also tempted to use transforms, but if I understand it right - the destination index cant be of the same index template as the source index. This will cause trouble when I will display graphs in Kibana. Do you have any recommendations on how I can proceed with this issue? ---

Hi @Rbb. Are you trying to create this baseline in a visualization? Lens supports [custom formulas](https://www.elastic.co/guide/en/kibana/current/lens.html#lens-formulas) that have a `shift` parameter that can aggregate over a different period. ---

I also want to split the data into several graphs and visualize the top 5 most visited pages(rum). I have up to now used aggregation based visualization. Is it possible to split it like this with lens as well? ---

Hi @Rbb. Sure, you can add the page url field to the Breakdown section in the Lens editor. ---

I want each page to be an individual graph as one can do by the split chart function in the aggregation based visualizations. I cant get the Breakdown feature to do that, can I? I found this related post: [Kibana Lens split chart](https://discuss.elastic.co/t/kibana-lens-split-chart/239120). Is this still the case? If so is there any way to both get the dynamic baseline and splitting charts? ---

Hi @Rbb. Sorry, no, we currently don't have the ability to split charts in Lens. [Here is the feature request tracking this](https://github.com/elastic/kibana/issues/72063). I don't think there is a way to have both a time-shifted baseline and split charts in the same visualization in Kibana. ---
