mo.ui.altair_chart error with timestamp and aggregation encode

the error appears on 0.9.33. tried 0.9.34 which seems to have fixed the issue but reactive binding doesn't work on chart selection, nothing from chart.value

Yep this was just fixed in latest. Can you share the code where you get no results from chart selection

here's the dataframe used for the chart

can you share copy/pastable code with the reproduciton?

appreciate the attention, here's the notebook

$ uv tool run marimo@0.9.34 edit --sandbox --port 2730 at.py

@lovuikeng i have a fix for this: https://github.com/marimo-team/marimo/pull/3135

THANK YOU!

that really helps

btw, out of topic here, is there example or script for this multi-column feature? https://x.com/themylesfiles/status/1864475849526816937 , i know it's still experimental, great to have it to save ui real estate, long scrolling is kind of tiring and context distracting 🙂

can't wait for it to become part of ui widgets

@lovuikeng its in the Settings Modal > Labs > Multi-column

yes, i'd noticed but don't know how to use it, i mean i don't see option to create multi column

Oh it’s in the column width option in the top right app settings

i see, shall try, thanks🙏

font size too adjust itself accordingly, NICE! really neat, thank you for such great addition to marimo 🚀
