I’m trying to use the Vega board in Quiver to plot a bar chart with a threshold line (as offered in the template), but it looks like the object set feeding into it can only have a maximum of 50k objects. I see that the bar plot chart works fine at a higher scale (even in the millions) however, though it doesn’t meet my needs. What options do I have for generating Vega charts with more than 50k objects, that ideally don’t require creating additional ontology entities? I don’t seem to be able to use transform tables either. ---

The 50k objects limit isn’t exactly on Vega charts: Vega plots accept data from transform tables which have a limit of 50k rows. If you want to plot a bar chart, I imagine that you run an aggregation in the Vega plot configuration, such as counting different values of a grouped by property. You could do this aggregation upstream of the transform table instead: in an [expression materialization card](https://www.palantir.com/docs/foundry/quiver/cards-index-materializations/#expression), you would define the same aggregation, and then feed this smaller number of rows to the transform table, instead of all objects. ---

Transform tables and Vega plots load all the data into the browser, so there are scale limitations compared to other cards. As @comew mentioned, we recommend filtering or pre-aggregate the data before feeding it into Vega, using cards of “Object set” or “Materializations” data types. ---
