Amazing stuff, I’m really excited to see Trellis charts.

As you can see I’ve been waiting for quite some time!

The weirdest part is that the engineer here who finally built them is named Richard, AND your tiny discourse picture looks eerily like him. (The effect kinda fades when you blow up the picture, but, whatever).

spooky stuff.

Awesome to see Trellis Charts on this! I think this one’s going to be a business user favourite.

Very interested by the Trellis charts but noticed that you can’t set individual reference lines or trend lines per grid item. Is this going to be implemented? At the moment reference/trend lines are unfortunately not useful with Trellis charts but I think they could be a valuable resource.

In regards to the Trellis Chart. Should it not honour the order of the column by which the individual charts are ordered? Also each chart should be allowed to have individual Y axis. Sometimes we want to look at different volume of data expecting the same curves. Currently they will all get the largest chart’s Y axis scale.

Wow, this is the first time in a year that I’ve been excited by something in the release notes. Trellis charts are a game changer. Please can there always be something this useful in a looker release?!?

Thanks for the feedback, Nolan— Taking a look at this.

I’ve noticed the same issue with the labels/values. In a dashboard this is particularly awkward.

Userlevel 1

Want to +1 the independent y-scale and trendlines for the trellis charts. I’ve been trying to use them now for a little over a month and most times I’ve reverted to another chart type because of the current limitations of the implementation.

Adding one other pain point that isn’t unique to trellis charts, but is certainly exacerbated by the additional padding / layout elements that it uses. When using trellis charts, I often end up losing the x-labels for the groups as well as (and especially) any value labels. It seems to be an issue related to spacing around chart elements and other series / collision detection. So far the only solution I’ve found is to make it enormous in a dashboard and even then, it may not work for someone else’s screen size.

Any suggestions?

At 643 px tall, neither the facet names nor the values will display. At 743px I get facet names.

Not until 1100 px tall do I get both, which goes beyond the browser’s viewheight, even if I zoom way out.

Let me know if there’s anything I can do to help QA. I realized that I didn’t mention I run Chrome, currently on Version 72.0.3626.121. Many of my end users are on Safari as well.

This is great feedback, thanks all! I’ve raised it internally.
