ArgumentTypeDetails
this: ui.chartui.ChartThe ui.Chart instance.
callbackFunctionThe callback to fire when the chart is clicked. The callback is passed three arguments: the x-value, the y-value, and the series name. Time values are represented in UTC epoch milliseconds, like "system:time_start" values on assets. If the user clicks on a legend entry to select an entire series, the x- and y-values are null. If the user clicks an already-selected point, all arguments are null, indicating the selection was cleared.
