Trends: Expand view to make it similar to Show Plots

[daavoo]

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).
