可以通过脚本替换实现itemGap分别在水平与垂直方向进行独立控制，我这里在`npm start`的 脚本前，添加了命令，比如:
`node ./patchEcharts.js&&set PORT=8004&&set RUN_ENV=START&&set
BUILD_ENV=PROD&&set BASE_PATH=%npm_config_basePath%&&max dev --progress`
后续在打包脚本中也需要同样的处理，需要注意的是，为了避免重复替换，替换后的字符串内容要做一个差异处理，比如减少一个空格。
patchEcharts.js
```
const replace = require("replace");
replace({
// regex: 'warning\\([^\n\r]*\\);',
regex:'var currentLineMaxSize = 0;',
//减少一个空格避免重复匹配替换, 其他replace保持一致
replacement: `
var currentLineMaxSize= 0;
//add-begin
let gapList = [];
if(typeof gap === 'string' || typeof gap === 'number'){
gapList = [gap, gap];
}else if(gap instanceof Array){
gapList = [gap[0], gap[1]];
}
//add-end
`,
paths: ['node_modules/echarts/lib/util/layout.js'],
recursive: true,
limit:1000,
silent: false,
multiline:true,
});
replace({
// regex: 'warning\\([^\n\r]*\\);',
regex:'y \\+= currentLineMaxSize \\+ gap;',
replacement: `
y+= currentLineMaxSize + gapList[1];
`,
paths: ['node_modules/echarts/lib/util/layout.js'],
recursive: true,
multiline:true,
});
replace({
// regex: 'warning\\([^\n\r]*\\);',
regex:'x \\+= currentLineMaxSize \\+ gap;',
replacement: `
//replace-begin
x+= currentLineMaxSize + gapList[0];
//replace-end
`,
paths: ['node_modules/echarts/lib/util/layout.js'],
recursive: true,
multiline:true,
});
replace({
// regex: 'warning\\([^\n\r]*\\);',
regex:"orient === 'horizontal' \\? x = nextX \\+ gap : y = nextY \\+
gap;",
replacement: `
//replace-begin
orient=== 'horizontal' ? x = nextX + gapList[0] : y = nextY + gapList[1];
//replace-end
`,
paths: ['node_modules/echarts/lib/util/layout.js'],
recursive: true,
multiline:true,
});
```
我看这个feature 23年已经提交了，但为何demo上还是没能实现对应功能
