3.9.10Removing all drawings from a chart

You can use ChartChange() to remove all the drawings from a chart:

Framework.ChartChange({

mode: "active", // or "all", or "single" plus a .chartId value

command: "remove-all-drawings"

});

Note: it is almost always inefficient and undesirable to change drawings by removing them and then re-creating them, rather than modifying the drawings.
