[xile611]

What problem does this feature solve?

spec 如下：

const spec = {
    
    crosshair: {
      trigger: 'click',
      gridZIndex: 401,
      labelZIndex: 501,
      xField: {
        visible: true,
        bindingAxesIndex: [0],
        line: {
          visible: true,
          type: 'line',
          style: {
            opacity: 1,
            lineDash: [2, 2],
            lineWidth: 1,
            stroke: '#193D7A'
          }
        },
        label: {
          labelBackground: {
            style: {
              fill: '#193D7A',
              outerBorder: {
                stroke: '#193D7A'
              }
            }
          },
          visible: true
        }
      },
      yField: {
        bindingAxesIndex: [1],
        visible: true,
        line: {
          visible: true,
          type: 'line',
          style: {
            opacity: 1,
            lineDash: [2, 2],
            lineWidth: 1,
            stroke: '#193D7A'
          }
        },
        label: {
          labelBackground: {
            style: {
              fill: '#193D7A',
              outerBorder: {
                stroke: '#193D7A'
              }
            }
          },
          visible: true
        }
      }
    }
  };

What does the proposed API look like?

{
clickTimer?: number;
}
