Description
In the VChart bar chart, the default display is the label of the corresponding value of the bar. I want to display something like ‘x-axis name: y value’ . What are the ways to customize the label display?
Solution
There are two recommended configuration methods:
Configure the formatting function through label.formatMethod.
The function parameter is (text: string | string [], data?: any) ,text is the default displayed text, and data is the related data.
The return value of the function can be a string or a string array. Among them, the string array will be displayed as a newline by default.
If you want to configure it as rich text, the return value is the rich text configuration object.
formatMethod🙁value, data) => `${data.name}: ${value}`
}
Configure the template string through label.formatter.
formatter: `{name} : {value}`
}
