allow deletion of data from Heat Figs with Patch()

I am trying to delete some data from a heat fig, and it doesn't seem to be possible with patch. With patch, you would return something like

fig = Patch()
del fig['data'][0][x][0]

to delete the first item in the heatfig. The issue is that the heatfig has the following structure:

{ "data": [
    {
      "x": ["2021-12-21T19:58:00.542000", "2021-12-21T19:58:01.542000", "2021-12-21T19:58:02.542000" ],
      "y": [13500.0, 13503.33591, 13506.67183 ],
      "z": [[599.8054, 581.1404, 570.4771 ],
              [678.9323, 644.2858, 610.9979 ],
              [576.6772, 568.9164, 565.6251 ],
    }]}

and so you would need to loop through each list in the z field to remove the first item as well (as the heatfig is a 3D array). We can't know ahead of time how many items are in the z field making it impossible to delete data.

Basically, if you want to remove the first timestamp in the fig, you would need the data to look like:

{ "data": [
    {
      "x": ["2021-12-21T19:58:01.542000", "2021-12-21T19:58:02.542000" ],
      "y": [13500.0, 13503.33591, 13506.67183 ],
      "z": [[581.1404, 570.4771 ],
              [644.2858, 610.9979 ],
              [568.9164, 565.6251 ],
    }]}

I don't want to load in the whole fig as state because it is quite large (and defeats the purpose of using a Patch()).
I haven't found a work around for this yet.

En el issue no se mencionan archivos ni pruebas. Empieza reproduciendo el ejemplo de Patch() de una figura de mapa de calor y sigue el comportamiento actual de patch para los datos anidados x, y y z. El trabajo estará terminado cuando se pueda eliminar una marca de tiempo de la figura, actualizando los valores z correspondientes, sin cargar todo el estado de la figura.
