Are you tired of dealing with unwanted user interactions in your ECharts visualization? Do you want to limit the user’s ability to hover, click, or zoom on specific series? Well, you’re in luck! In this article, we’ll show you how to disable all interaction with specific series in ECharts, giving you full control over the user experience.
Why Disable Interaction?
Before we dive into the solution, let’s take a step back and discuss why you might want to disable interaction with specific series in the first place. Here are a few scenarios:
- Visual clutter reduction**: By disabling interaction on certain series, you can reduce visual clutter and make your chart more readable.
- Simplify user experience**: Limiting user interaction can simplify the overall user experience, making it easier for users to focus on the most important data.
- Improve performance**: Disabling interaction on complex series can improve the overall performance of your chart.
The Solution: Using the `silent` Property
The `silent` property is the key to disabling interaction with specific series in ECharts. By setting `silent` to `true`, you can prevent the series from responding to user interactions such as hover, click, and zoom.
series: [{
type: 'line',
data: [...],
silent: true // Disables interaction for this series
}]
However, using the `silent` property alone may not be enough. You may also want to prevent the series from being highlighted when the user hovers over it. To do this, you can set the `emphasis` property to `null`:
series: [{
type: 'line',
data: [...],
silent: true,
emphasis: null // Prevents highlighting on hover
}]
Disabling Interaction for Multiple Series
What if you need to disable interaction for multiple series? You can do this by applying the `silent` property to each series individually:
series: [{
type: 'line',
data: [...],
silent: true
}, {
type: 'bar',
data: [...],
silent: true
}, {
type: 'scatter',
data: [...],
silent: true
}]
Alternatively, you can use the `seriesIndex` property to disable interaction for multiple series at once:
option = {
series: [...],
seriesIndex: [0, 1, 2], // Disables interaction for series 0, 1, and 2
silent: true
}
Disabling Specific Interactions
What if you only want to disable specific interactions, such as hover or click? ECharts provides a range of properties that allow you to customize the interaction behavior:
series: [{
type: 'line',
data: [...],
hoverOffset: 0, // Disables hover effect
clickable: false, // Disables click event
tooltip: null // Disables tooltip
}]
Using `itemStyle` to Customize Appearance
When you disable interaction, you may also want to customize the appearance of the series to indicate that it’s not interactive. You can use the `itemStyle` property to change the color, opacity, or other styles of the series:
series: [{
type: 'line',
data: [...],
silent: true,
itemStyle: {
normal: {
color: 'gray', // Changes color to gray
opacity: 0.5 // Changes opacity to 50%
}
}
}]
Real-World Examples
Let’s take a look at some real-world examples of disabling interaction with specific series in ECharts:
| Example | Description |
|---|---|
| Disabling interaction for a specific line series | series: [{ type: 'line', data: [...], silent: true }]> |
| Disabling interaction for multiple bar series | series: [{ type: 'bar', data: [...], silent: true }, { type: 'bar', data: [...], silent: true }]> |
| Disabling hover effect for a scatter series | series: [{ type: 'scatter', data: [...], hoverOffset: 0 }]> |
Conclusion
Disabling interaction with specific series in ECharts is a powerful way to customize the user experience and improve the overall readability of your charts. By using the `silent` property, `emphasis` property, and other customization options, you can create charts that are both visually appealing and easy to use.
Remember to experiment with different properties and options to achieve the desired effect. And if you have any questions or need further assistance, don’t hesitate to reach out to the ECharts community!

Here are 5 Questions and Answers about “How to disable all interaction with specific series in echarts?”
Frequently Asked Question
Get answers to your most pressing questions about disabling interactions with specific series in echarts!
How can I disable all interactions for a specific series in echarts?
You can disable all interactions for a specific series by setting the `silent` property to `true` in the series options. For example: `series: [{ type: ‘line’, silent: true, data: […] }]`. This will prevent the series from responding to mouse and touch events.
What happens if I want to disable only hover effects for a specific series?
To disable only hover effects for a specific series, you can set the `hoverOffset` property to `0` in the series options. For example: `series: [{ type: ‘line’, hoverOffset: 0, data: […] }]`. This will prevent the series from displaying hover effects, but still allow other interactions.
Can I disable interactions for a specific series, but still allow zooming and panning?
Yes, you can disable interactions for a specific series while still allowing zooming and panning by setting the `animation` property to `false` and `tooltip.trigger` property to `’none’` in the series options. For example: `series: [{ type: ‘line’, animation: false, tooltip: { trigger: ‘none’ }, data: […] }]`. This will prevent the series from responding to mouse and touch events, but still allow zooming and panning.
What if I want to disable interactions for all series in a chart?
To disable interactions for all series in a chart, you can set the `silent` property to `true` in the chart options. For example: `chart.setOption({ silent: true });`. This will prevent all series in the chart from responding to mouse and touch events.
Are there any other ways to disable interactions for a specific series?
Yes, you can also disable interactions for a specific series by setting the `emphasis` property to `null` in the series options. For example: `series: [{ type: ‘line’, emphasis: null, data: […] }]`. This will prevent the series from responding to mouse and touch events, and also remove the hover effect.
