[GitHub] [echarts] ljh257110 opened a new issue #15705: 使用datazoom时，数据的分块加载方案 Block loading scheme of data when using datazoom

ljh257110 opened a new issue #15705:
URL: https://github.com/apache/echarts/issues/15705


   ### What problem does this feature solve?
    能否实现柱状图、折线图、柱状折线混合图等在使用datazoom时，数据的分块加载方案，目前实现方案需要一开始就获取到所有数据，这在数据量大或者数据本身的来源需要很多计算时会有问题 
   Can you implement the block loading scheme of data when using datazoom, such as histogram, broken line graph and column broken line mixed graph? At present, the implementation scheme needs to obtain all data from the beginning, which will have problems when the amount of data is large or the source of data itself needs a lot of calculation
   
   ### What does the proposed API look like?
   使用datazoom时，数据可以当触发滑动事件时再去加载，或者滑动时直接变更整个的数据，而不是现在可以一个刻度一个刻度的滑动
   When using datazoom, the data can be loaded when the sliding event is triggered, or the whole data can be changed directly during sliding, instead of sliding scale by scale
