100pah commented on issue #9265: xAxis.nameGap and yAxis.nameGap should be set automatically given grid.containLabel URL: https://github.com/apache/incubator-echarts/issues/9265#issuecomment-434022070 Currenly `containLabel` only considered axis labels, but not consider axis name. @jbadilla  This axis lable is visually unpleasant because the default `nameGap` is `0`. Another issue #9286 gave a related situation that the axis name might overflow the rendering area. To make the layout wisely, I think two enhancements can be taken into accout (and the two enhancement might be independent with each other in implementation): ### (A) Enhanse the layout calculation of axis name: adjust it based on axis label and viewport. Keep the current behaviors of `nameLocation` and `nameGap`, and add a new option `nameLocationAdjust` (or some likely name), which enable axis name to be auto adjusted to avoid interfering with axis labels and overflow the viewport, following the strategy below: **Procedure X:** Layout axis name by the given `nameLoation` and `nameGap`, and then adjust it to avoid interfering with axis labels. Finally the relative location of axis name with axis line get. Detailedly, in this case, `nameGap` is not the gap with axis line any more, but actually is the gap with the bounding rect of both axis line and axis labels. Procedure X will be executed twices if `containLabel` is set, the same as current implementation: 1. The first execution is before the "coordinate system update stage", based on the estinamed axis label layout. 2. The second execution is on the "cartesian rendering stage", based on the accrate axis label layout. **Procedure Y:** Ajust the axis name to avoid overflowing the viewport (if it makes the axis name interfere with axis labels again, leave them there). Notice the overflow also need to be taken into account when `nameLocation` is `start` or `end`, like #9286 issued, which enables that when two cartesian exists axes align with each other without dynamic axis names overflow. Procedure Y is only be executed in the "cartesian rendering stage", after Procedure X executed. ### (B) Enhanse the cartesian rect determine calculation when `containLabel` Currently `containLabel` has considdered axis label (and rotation). We should make it take into account the located axis name also, whatever the (A) is implemented or not. But the logic looks not neat, a little complecated :(
