How do I merge two items in a pie chart into one for counting?

1. Problem scenarios

Assume that you need to use pie charts to count the number of fruit types, but in the process of input, you can enter "apple" into "Little Apple 」. The following pie chart effect is obtained:

Question:How do I put little Apple and Apple in the same category for statistics?

2. Solution

View the following video for specific settings:

Code snippet:

function afterFetch(content) {
  const categies = (content.series[0] || {}).data || [];
  categies.forEach(item => {
    if (item.name === '苹果' || item.name === '小苹果') {
      item.name = '苹果';
    }
  });
  content.series[0].data = categies;
  return content;
}

From one example to another:

Suppose you not only classify "apple" and "Little Apple" as "apple", but also need to classify "pineapple" and "Pineapple" as "Pineapple". What should you do?

Then you only need to add another judgment.

function afterFetch(content) {
  const categies = (content.series[0] || {}).data || [];
  categies.forEach(item => {
    if (item.name === '苹果' || item.name === '小苹果') {
      item.name = '苹果';
    }
    if (item.name === '菠萝' || item.name === '凤梨') {
      item.name = '菠萝';
    }
  });
  content.series[0].data = categies;
  return content;
}
