🤔 [QUESTION]当点击图例的某个选项后，触发了图表的渲染之后，想同步更新X轴的文字

·比如当点击了上周期触发了图表的渲染之后，想同步更新X轴的文字，该怎么做？

Start with G2Plot's legend-selection and chart-rendering entry points, using the screenshot and the described “previous period” interaction to reproduce the behavior. Done means selecting a legend option causes the X-axis text to update in sync with the resulting chart render; the issue provides no file or test path, so locate the relevant API or example first.
