Plotly.js blocks UI while rendering large data set. Does it have any downsampling functionality?












1














I am using Plotly.js to render a histogram2dcontour plot in a mobile application. The data is approx ~10^6 data points. It takes Plotly.js almost 3-4 seconds to render the plot. While plotting, the UI of the app hangs since the data is huge and plotting it is a blocking call. I understand that the data has too many points and this kind of behavior is expected.



Does plotly.js provide any functionality for downsampling huge data?
Or any effective downsampling techniques in Swift?



Any other suggestions are also welcome.
