Old graphs not removed when updating data with scattered graph

[Linho1219]

For example:

functionPlot({
  target: "#playground",
  data: [
    {
      fn: "x^2",
      graphType: "polyline",
    },
  ],
});

And when calling:

functionPlot({
  target: "#playground",
  data: [
    {
      fn: "x^2",
      graphType: "scatter", // changed to scatter
    },
  ],
});

The old graph still exist. This problem appears when graphType changes from scatter to other values, or other values to scatter.
