Try `tooltips = layerTooltips(*emptyArray())`
I would guess it groups data by date (7 groups). Interaction with grouping by "type" gives us 14 groups in total. That means 14 bars in each datapoint. The plot...
It seems the question was resolved.
The default color palette is not configurable at the moment. Could be a good featue.
Absolutely, try to use [`scaleColorBrewer()`](https://lets-plot.org/kotlin/-lets--plot--kotlin/org.jetbrains.letsPlot.scale/scale-color-brewer.html) / [`scaleFillBrewer()`](https://lets-plot.org/kotlin/-lets--plot--kotlin/org.jetbrains.letsPlot.scale/scale-fill-brewer.html) with your plot.
Was fixed in 4.7.3
A workaround was added in v4.7.1, see: [example notebook](https://nbviewer.org/github/JetBrains/lets-plot-kotlin/blob/master/docs/examples/jupyter-notebooks/f-4.7.1/facet_multiline_titles.ipynb).
Not sure why it is necessary to override methods like `toList`. KtNDArray will provide an iterator (ListIterator maybe) and all the rest will work out of the box IMO. Alternatively...
IMHO this is not an issue. When user works with `KtNDArray` all expressions have type `KtNDArray` and all extensions work as expected. A code which doesn't know about kotlin numpy...
Yes, (1) certainly is not looking good.
