Sunburst Chart Selection

[DanielOC]

Hi All,

I have created a sunburst chart and would like to select a segment the use this selection as a filter. The sunburst chart should output the selection as a Boolean in a new column, however, when I make a selection, this new column only outputs false. I can never manage to get a true value in this column. Is this an error on my behalf or a bug with the node?

Thank you

Dan

I double checked that the “publish selection event” in the Table View is selected, as also the “enable subscription of selection” in the Sunb…
