URL: https://github.com/apache/echarts/issues/19843

   ### Version
   
   5..5.0
   
   ### Link to Minimal Reproduction
   
   https://echarts.apache.org/examples/en/editor.html?c=bar-waterfall
   
   ### Steps to Reproduce
   
   I want the width/height of the column or bar chart for each data bar based 
on that width or height should be known in the **label-formatter callback.** 
Based on this we need to show the user-selected icon size with respect to width 
or height of the individual bar
   
   For example, the formula is iconSize = height or width * icon size in 
percentage the user selected. 
   EX: Arrow Size = 100 pixels * 50% = 50 pixels (here 100 is with or height of 
the bar and 50 is the user-selected icon size percentage based on bar with or 
height that icon souls )
   
   Example echart options like: 
   option = {
     title: {
       text: 'Waterfall Chart',
       subtext: 'Living Expenses in Shenzhen'
     },
     tooltip: {
       trigger: 'axis',
       axisPointer: {
         type: 'shadow'
       },
       formatter: function (params) {
         var tar = params[1];
         return tar.name + '<br/>' + tar.seriesName + ' : ' + tar.value;
       }
     },
     grid: {
       left: '3%',
       right: '4%',
       bottom: '3%',
       containLabel: true
     },
     xAxis: {
       type: 'category',
       splitLine: { show: false },
       data: ['Total', 'Rent', 'Utilities', 'Transportation', 'Meals', 'Other']
     },
     yAxis: {
       type: 'value'
     },
     series: [
       {
         name: 'Placeholder',
         type: 'bar',
         stack: 'Total',
         itemStyle: {
           borderColor: 'transparent',
           color: 'transparent'
         },
         emphasis: {
           itemStyle: {
             borderColor: 'transparent',
             color: 'transparent'
           }
         },
         data: [0, 1700, 1400, 1200, 300, 0]
       },
       {
         name: 'Life Cost',
         type: 'bar',
         stack: 'Total',
         label: {
           show: true,
           position: 'inside'
         },
         data: [2900, 1200, 300, 200, 900, 300]
       }
     ]
   };
   
   
   ### Current Behavior
   
   NA
   
   ### Expected Behavior

bar.
