https://canvasjs.com/docs/charts/chart-options/data/tooltipcontent/ provides excellent examples of customising the tooltip content. The examples are however limited to column charts. Is there a similar example for a shared tooltip content on a line chart. E.g. Customising the tooltip on a line chart with multiple data series to also show the XAxis value. How can I add the XAxis value to a SHARED tooltip content on a LINE chart?
