this is the design drawing given by the designer:
:Y3markAreamarkLineY:
now requires that the Y axis be consistent with the design drawing. I can"t do it with a custom Y axis. Define to yAxis that the data, chart cannot be rendered. How can this situation be realized?
markLine cannot be below the line, so I finally simulated it by setting the width to 0 with markArea. As for the words "rainstorm" above and the custom data, on the Y axis, they are finally located with tags.
