确保每个图表都遵循相同的颜色和字体，从而在报表、仪表板和演示文稿中提供作为一个整体的品牌外观。

Chart themes provide a simple yet powerful way to standardize the appearance of charts by applying predefined color schemes, fonts, and styling options across visualizations. Instead of manually adjusting each element, users can quickly switch between themes to achieve a consistent, professional look that aligns with brand guidelines or presentation needs. The benefits include improving readability, enhancing accessibility - with inclusive color palettes - and ensuring visual consistency across multiple charts or entire dashboards. Chart themes improve the process of creating impactful, audience-ready data visualizations.

Several .NET WPF chart components offer the ability to add themes, including:

  • Telerik WPF Chart (part of Telerik UI for WPF) allows you to switch seamlessly between chart themes, enhancing readability, accessibility, and visual appeal.
  • DevExpress WPF Chart (part of DevExpress WPF) lets you apply customizable chart themes, ensuring consistent fonts and colors that align with brand standards.
  • TeeChart WPF (pat TeeChart for .NET Standard Business Edition by Steema) facilitates professional data storytelling by using chart themes to improve style management.
  • Syncfusion WPF Chart (part of Syncfusion Essential Studio Enterprise) enables you to unify chart appearance using flexible themes, saving time and ensuring design consistency.

导出为 XLS/XLSX 允许用户访问图表背后的原始数据，从而更轻松地以电子表格友好的格式分析、审核或共享见解。

Exporting charts to XLS or XLSX formats enables developers to extract the structured underlying data from visualizations and make it available for deeper analysis or downstream processing. Rather than being confined to image or PDF exports, this approach allows for easy integration of chart data with spreadsheet tools and data workflows. By converting charts into Excel files, users gain the ability to manipulate, filter, or augment data, ideal for reporting, auditing, or business intelligence scenarios where numerical insights must be both visual and actionable.

Several Blazor charting controls offer the ability to export charts to XLS/XLSX including:

  • FusionCharts Blazor Suite XT (part of FusionCharts Suite XT) offers chart-data export to XLSX (Excel) format via its export menu or API, supported in both client-side and server-side export modes when exportEnabled is set, providing flexible, one-click access to underlying chart data.
  • TeeChart .NET for Blazor by Steema Software enables chart exports not only as images and PDFs, but also as structured data to Microsoft Excel formats (XLS/XLSX), along with exports to XML, HTML, CSV, and native chart formats, supporting a full range of sharing and reuse scenarios.
  • Syncfusion Blazor Chart (part of Syncfusion Essential Studio Enterprise) provides a unified ExportAsync method enabling direct export of chart content, including underlying data, to XLSX or CSV files. This improves distribution of chart data alongside visual exports, especially in analytics and reporting contexts.

突出显示多个变量之间的关系

多维图表揭示了多个指标或轴的模式和趋势，使其成为复杂数据分析的理想选择。

Multi-dimensional and relationship charts allow developers to present complex data structures and inter-variable relationships in a way that’s visually intuitive and analytically powerful. These chart types are essential for exploring correlations, comparing grouped metrics, and visualizing distributions across multiple dimensions. They are commonly used in statistical dashboards, performance analysis tools, and scientific applications where simple line or bar charts aren’t sufficient to capture the full context of the data.

Common charts include:

  • Combination Charts allow developers to overlay different chart types, such as bars, lines, and areas, within a single axis system, enabling comparison across metrics with varying scales or data types.
  • Radar & Polar Charts display multivariate data in a circular format, ideal for comparing values across categories that share a common center point, such as performance metrics or skill assessments.
  • Radial Chart formats extend circular visualization into more structured layouts, such as radial bar or radial line charts, providing a compact and distinctive way to show cyclical data or category-based trends.
  • Scatter & Bubble Charts plot data along two or three axes, often using the size of bubbles to represent an additional variable, making them ideal for visualizing trends, clusters, and outliers in high-volume datasets.

用生动的地图图表转换数据，可轻松比较值、揭示区域模式并发现可操作的见解。

A map chart is a visual representation of data that displays values across geographic regions using colors, shading, or markers, making complex information easier to interpret. By placing data in a spatial context, map charts help users quickly identify regional patterns, trends, and outliers that might be overlooked in traditional tables or graphs. They are particularly useful for comparing values across countries, states, or counties, enabling clearer insights into geographically distributed data. Common use cases include illustrating population density, highlighting election results, analyzing sales performance by region, and presenting economic indicators. The key benefits of map charts include their ability to simplify complex datasets, provide intuitive comparisons, and support data-driven decision-making by visually connecting numbers with real-world locations.

Several .NET Core chart controls offer map charts including:

  • DevExpress WinForms Chart (part of DevExpress WinForms) lets you visualize geographic data with customizable map charts, enabling precise regional comparisons.
  • ComponentOne Charts for WinForms (part of ComponentOne Studio WinForms by MESCIUS) allows you to transform spatial datasets into interactive map charts.
  • Telerik WPF Chart (part of Telerik UI for WPF) facilitates powerful geographic storytelling through map charts, helping users reveal trends and explore regional performance.
  • Infragistics WPF Charts (part of Infragistics Ultimate UI for WPF) enables you to analyze data contextually with map charts, combining intuitive design and clear visualization.

更好地控制图表图例

LightningChart JS v8.0 引入了经过全面改进的图例系统，具有更智能的默认值、灵活的定位和增强的自定义功能。

LightningChart JS is a high-performance JavaScript charting library that utilizes WebGL rendering and GPU acceleration to deliver exceptional performance for a wide range of data visualization needs. It is designed to handle large datasets and complex visualizations with ease, enabling developers to create interactive and visually appealing 2D and 3D charts. Ideal for applications demanding smooth real-time data updates, such as financial platforms, engineering tools, scientific research dashboards, and industrial monitoring systems, LightningChart JS provides a comprehensive API for customization and integration into web-based projects.

The LightningChart JS v8.0 update completely reworks legend functionality, making legends a property of the chart, removing visual obstructions, and improving adaptability to available space. The API configuration is now more intuitive and capable, with built-in options supporting a wider range of use cases. Plug‑in support also enables easy extension or customization of legend behavior. By default, legends now appear automatically beneath trends, reducing developer setup time, while still allowing you to manually create multiple legends when needed. You can position legends using built-in presets or define custom placements, and control click behavior using either the provided handlers or your own. When creating series, you can also exclude specific ones from appearing in legends, giving you fine-grained control over legend content.

To see a full list of what's new in v8.0, see our release notes.

LightningChart JS is licensed per developer and is available as an annual license with 1 year support. See our LightningChart JS licensing page for full details.
