Error when calling displayGraph(). = Canvas is already in use.

Canvas needs to be cleared before redrawing

possible solution at https://stackoverflow.com/questions/40056555/destroy-chart-js-bar-graph-to-redraw-other-graph-in-same-canvas

using .destroy() or const context = canvas.getContext('2d'); context.clearRect(0, 0, canvas.width, canvas.height);
