Dus1988 opened a new issue #10389: DataZoom Slider Does Not Respect Y Axis min if positive value
URL: https://github.com/apache/incubator-echarts/issues/10389
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   Create a 2 axis Cartesian chart
   make x axis category, and y axis a value axis. 
   set y axis minimum to a positive value
   set datazoom on y axis as a slider
   Notice chart y axis adheres to y-axis minimum
   
   ### What is expected?
   If y axis has a min and/or max set, the data zoom should adhere and have the same range as the chart's y axis
   
   ### What is actually happening?
   chart's y axis listens to y axis min, but data zoom bottom(start) on y axis is always equal to 0 if yAxis.min is a positive number. If min is set to a negative number, datazoom will respect it. 
   
   ---
   this can be replicated on the demo linked below. 
   
   notice datazoom y axis bottom is equal to -30.
   change y axis min to 10.
   notice datazoom y axis bottom is equal to 0
