JavaScript Error when clicking chart datapoints

[nbanyan]

We're seeing a couple issues when clicking on chart datapoints in playbooks.

• In bar_graph.tsx and line_graph.tsx the element[0] fed into props.onClick doesn't have an _index member, so undefined is passed instead of the number in index.
• In the debugger these onClick drop directly into filterStarted or filterActive, but in both cases the argument they receive is undefined even if the onClick functions are modified to pass a real number into the onClick call.

Uncaught TypeError: Cannot read properties of undefined (reading '0')
