去掉分面图的 frame，并且自定义样式 #5644

可以先设置 frame：false，然后通过 point.viewStyle 的 plotFill ，plotStroke 等设置

import { Chart } from '@antv/g2';

const toNaN = (d) => (d === 'NaN' ? NaN : d);

const chart = new Chart({
  container: 'container',
  width: 800,
  height: 800,
  paddingLeft: 70,
  paddingBottom: 70,
});

const repeatMatrix = chart
  .repeatMatrix()
  .data({
    type: 'fetch',
    value: 'https://assets.antv.antgroup.com/g2/penguins.json',
    transform: [
      {
        type: 'map',
        callback: ({
          culmen_depth_mm: cdepth,
          culmen_length_mm: clength,
          flipper_length_mm: flength,
          body_mass_g: bmass,
          ...d
        }) => ({
          ...d,
          culmen_depth_mm: toNaN(cdepth),
          culmen_length_mm: toNaN(clength),
          flipper_length_mm: toNaN(flength),
          body_mass_g: toNaN(bmass),
        }),
      },
    ],
  })
  .encode('position', ['culmen_length_mm', 'culmen_depth_mm']);

repeatMatrix
  .point()
  .attr('frame', false)
  .encode('color', 'species')
  .viewStyle('plotStroke', '#aaa')
  .viewStyle('plotOpacity', 0.5);

chart.render();
