When creating ring charts with ECharts, you often need to adjust the center text style, such as changing the color. This article will explain in detail how to modify the text color of the center of the ECharts ring diagram.

We assume that the ring graph center text is generated through the ECharts configuration item, not later added. When modifying the center text color, the key is to find configuration items that control text styles, which depends on how you create the text. ECharts usually defines text directly using title attribute or in series configuration.

Method 1: Use title attribute

If the central text is configured through title attribute, you need to modify color attribute in textStyle attribute. For example:

 title: {
    text: 'Central text',
    textStyle: {
        color: '#FF0000' // red}
}

Method 2: Define text in series configuration

If the central text is defined in the series configuration, you need to find the corresponding text style configuration item according to your code and modify color attribute. Different series types (such as pie and ring ) may be configured differently, please refer to the official ECharts documentation.
