Data decimation

[Coding-Kiwi]

I have a chart where the x axis is time and the y axis is a number there is a data entry every 10 seconds across 48h, so about 17280 entries. When trying to render the chart it get very laggy or even crashes the browser.

Now I could simply pre-filter the dataset using ramer-douglas-peucker for example but I also want to be able to zoom in to for example the last hour of data.

My guess would be that I need multiple datasets and clicking on the "last hour" button swaps out the whole dataset instead of using the zoomX method.

Is there a better way to do it?
