How to change chart theme to valo dark?
Its probably similar to changing a layout variant, which is something along the lines of: addThemeVariants(SplitLayoutVariant.LUMO_SMALL)
I am curious as to what would work though, so if you have figured it out please post your solution!
Unfortunately there’s no dark mode for charts just yet. See https://github.com/vaadin/vaadin-charts/issues/379.
