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

#vchart #visactor #charts

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)'
          }
        }
      }
    }
  },

  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';
