I used Charts/danielgindi..
When a graph is chosen, the spotlight works correctly. However what I would like is to spotlight the middle graph on the primary display screen when no graph is chosen.

chartView.highlightValue(x: 3, dataSetIndex: 3, dataIndex: 3)

chartView.highlightValue(Spotlight(x: 3, dataSetIndex: 3, stackIndex: 3))

I wrote the code in the identical method as above, however it failed. Assist me. everybody
