`Trends`: Expand view to make it similar to `Show Plots`

The current `Trends` view it's not very friendly to use when multiple metrics are selected and used to generate the `Trends.` There is not much room to compare and visualize and I find myself constantly scrolling.

I think that it would be nice to expand `Trends` in order to have a UX similar to the current state of the `Show Plots` view.

Background use case:

I have a dataset that gets updated every ~day. The dataset has ~20 classes and I generate a metric for each class (counting the current number of instances in the dataset). I find `Trends` really useful to visualize the evolution of the dataset but the current view has some limitations (described above).
