   Here's a revised code snippet implementing the dynamic adjustment of yAxis.max based on whether all data points are below zero:
   
   const data = [-1, -2, -3]; // Example data
   const threshold = 220;
   
   // Check if all data points are below zero
   const allBelowZero = data.every(value => value < 0);
   
   // Dynamically set yAxis.max based on the condition
   const maxY = allBelowZero ? threshold + 10 : null;
   
   const option = {
     xAxis: {
       type: 'category',
       data: ['A', 'B', 'C'] // Example categories
     },
     yAxis: {
       type: 'value',
       min: threshold,
       max: maxY // Set to threshold + 10 if all data points are below zero
     },
     series: [
       {
         data: data,
         type: 'bar'
       }
     ]
   };
   
   This adjustment allows for a more dynamic setting of the yAxis.max based on the data provided, ensuring the chart accommodates the range while avoiding hard-coded values. It keeps the configuration adaptable and avoids unnecessary complexity in the input dialogs or source code.
