keep Datazoom slider independent of data updates
rajvengala opened a new issue #10285: Option to keep Datazoom slider independent of data updates
URL: https://github.com/apache/incubator-echarts/issues/10285
### What problem does this feature solve?
Currently, when slider is moved, chart shows the data for the slider window. For my use case, for some windows, we fetch new data on slider move with different granularity.
For example:
1. Initial render - all data points have 1 hour granularity. Slider range is 0 to 100
2. Slider range is changed to 50-60. New data is fetched with 1 minute granularity. Now, the entire chart data is updated to look like below
1 hour granularity 1 min granularity 1 hour granularity
3. After the above 2 steps, slider is not reflecting the correct trend.
### What does the proposed API look like?
