Hi dear developers, Here we'd like to discuss about https://github.com/apache/incubator-echarts/issues/7651 . Since the issues is in Chinese, here I'm going to describe it in English.
[image: axisPointer position.png] Basically, it is required in the issue that the cross point of the axisPoint always snap to data point. In this case, the x position of the cross point is decided by mouse position, and the y position by the data of the corresponding x position. But currently, ECharts doesn't provide a method for the y position to be at data position. I'm not sure if *snap* is the correct word since currently the snap option in axisPoint seems to mean to be near to the data but not compulsively. Expected: https://gupiao.baidu.com/stock/sh000001.html?from=aladingpc Current ECharts: http://gallery.echartsjs.com/editor.html?c=x8K2BwAFx5&v=2 We'd like to discuss in this email: 1. Should we implement the feature as the *Expected* example shows? 2. Should this be called *snap* or something else? 3. Should we provide an option or make this default? 4. Is there anything we should be aware of when implementing this? @100pah Zhang Wenli http://zhangwenli.com
