question: echarts one-time rendering data multi-stutter problem, please ask how to deal with
problem description: line chart, rendering data is about 400items, each with 30 points. When rendering at one time, the data processing is very fast, but echarts rendering is very slow
related screenshots:
try: try to render 5 pieces of data at a time, which is much faster, but it is still an unacceptable time. It takes about 1 second to render
.data is not slow because it is local data, so basically the requested time can be controlled within 1 second, but rendering takes a long time. Now only the first five of them are rendered, but it feels very slow. I have another question. Please take a look at https://codeshelper.com/q/10.
not to mention rendering. Let's just say it's slow for you to request these 400 pieces of data, right?
400 points is not a problem. Put the operation of rendering and Filter data
