Echarts data graphics rendering, the amount of graphics data is relatively large, after rendering, click on the graphics to optimize the rendering, the amount of data may be large, and an

This error, the code is definitely no problem, because the first time the default loading is normal display, but there is a problem when re-rendering.
This is to limit the time when
setOption is called. If the process of
dispatchAction is not finished, calling
setOption again in the middle will loop once.
Looking at the relevant information, there is a method to set the
setOption delay that seems to be feasible, but the time given to me is very long and it is useless. I can only find another way out. This reason must be repeated when Echarts was drawing the picture, because when I first initialized the first picture, it was rendered normally. What if I failed to redraw the picture after the query? Is it possible to erase and redraw the previous Echarts diagram?
It is possible in theory, but also in practice. I found a clear method in Echarts. Just do `clear` before
setOption and execute
setOption: the code is as follows:
The method of passing time delay:
