I am afraid that programmatically showing or hiding series is currently not supported out of the box, thus we cannot guarantee that the workaround you found will work in further releases. I would suggest you to submit a feature request to our feedback portal
, so other members of the community can evaluate, comment on and vote for it. Most voted ideas are included in next KendoUI releases. Although I recommend against it, you could use the _legendItemClick method as a workaround, however you should keep in mind that using private methods is generally considered a bad practice. For convenience I prepared this
small example, which demonstrates the described functionality.
