Is there a way to partially re-render a plot?

[batearedcollie]

I have a plot showing 2 data streams, the first is a large heatmap and is static over the lifetime of the component. The second is a line on the heat map and needs to be updated continually. However, the updates are slow presumably because both datasets are being rendered on state refresh. Is there an option or way I can construct the component such that the large heatmap does not need to re-render when state is updated?

Any help is appreciated. Thanks.
