🐛 [BUG]折线图设置好y轴的min，max后，渲染的piont被坐标轴覆盖


The issue provides only a screenshot and does not name a file, test, or reproduction example. Start by locating the line-chart handling for configured y-axis min and max, then reproduce the overlap shown in the image. Done means the rendered points are not covered by the axis when those bounds are set, with a regression test if the existing test structure supports it.
