How to configure the style of pager arrow in VChart legend?

Problem Description

I used a dark theme and hope to make the page flipper style more prominent. How should I configure it?

Solution

Legend pager corresponds to the configuration of pager.

• The pager text color can be configured through pager.textStyle.fill.
• The page flipper button color can be configured through pager.handler.style.
• The style of the page turning button in the unavailable state needs to be configured through pager.handler.state.disable.fill.

  legends: {
    visible: true,
    pager:{
      textStyle:{
        fill:"rgb(170,170,170)"
      },
      handler:{
        style:{
          fill:'rgb(170,170,170)'
        },
        state:{
          disable:{
            fill:'rgb(47,69,84)'
          }
        }
      }
    }
  },

      id: 'id0',
      values: [
        { type: 'oxygen', value: '46.60' },

  outerRadius: 0.8,
  innerRadius: 0.5,
  padAngle: 0.6,
  valueField: 'value',
  categoryField: 'type',
  legends: {
    visible: true,
    pager:{
      textStyle:{
        fill:"rgb(170,170,170)"
      },
      handler:{
        style:{
          fill:'rgb(170,170,170)'
        },
        state:{
          disable:{
            fill:'rgb(47,69,84)'
          }
        }
      }
    }
  },
}

const vchart = new VChart((spec), { dom: CONTAINER_ID });
vchart.renderSync();

vchart.getCanvas().style.outline = '1px solid orange';
