   **TITLE**
   
   [Feature] Pieces in visualMap do not support gradients
   
   **BODY**
   
   ### What problem does this feature solve?
   
   In many scenarios, the color in visualMap needs to be gradient. For example, if the warning meets the conditions, it is highlighted. Although the data in the series is assembled into an array object to set the gradient color, it is very inconvenient to display in this way.
   
   ### What does the proposed API look like?
   
   visualMap: [
    {
      type: 'piecewise ',
      pieces: [
       {
         value: 123,
         label: '123 (custom special color)',
         color: {
             type: 'linear',
             x: 0,
             y: 0,
             x2: 0,
             y2: 1,
             colorStops: [{
                 offset: 0, color: 'red' // color at 0%
             }, {
                 offset: 1, color: 'blue' // color at 100%
             }],
             global: false // default is false
           }
       },
       {
           outOfRange: {
                 color: {
                     type: 'radial',
                     x: 0.5,
                     y: 0.5,
                     r: 0.5,
                     colorStops: [{
                         offset: 0, color: 'red' // color at 0%
                     }, {
                         offset: 1, color: 'blue' // color at 100%
                     }],
                     global: false // default is false
                 }
           }
       }
      ]
    }
   ]
