Dynamically Adjust Chart Size to Prevent Points from Leaving Chart

[NestorLiao]

I had implemented a simulation about "Isotropic Persistent Random Walk" where points were moving within a chart, and I had to ensure that the points always remained within the boundaries of the chart.
I add below code in every iteration/pitch which generate a GIF eventually.

 for _ in 0..args.frame_total {
        let mut chart = ChartBuilder::on(&root)
            .caption(
                "Isotropic Persistent Random Walk",
                ("sans-serif", 40).into_font(),
            )
            .x_label_area_size(20)
            .y_label_area_size(40)
            .build_cartesian_2d(o_cell.v.x - 1.0..o_cell.v.x + 1.0, o_cell.v.x - 1.0..o_cell.v.y + 1.0)?
        .......    
          .......
        o_cell.v.x = n_cell.v.x;
        o_cell.p.x = n_cell.p.x;
        o_cell.v.y = n_cell.v.y;
        o_cell.p.y = n_cell.p.y;
        ....

But the chart didn't update follow the cell's position.

I'd like to thank you if you know how to do this with plotters :-)
