Common Use Cases

Business Dashboard Metrics

Display KPIs, sales data, or performance metrics with enhanced 3D visualization for executive dashboards.

Financial Data Visualization

Render stock prices, market trends, or financial comparisons with datetime axes and multiple series.

Scientific Data Presentation

Visualize experimental data, measurements, or research findings with logarithmic or numeric axes.

Product Comparison

Compare product features, ratings, or sales across categories with grouped or stacked columns.

Time-Series Analysis

Display trends over time with datetime axes and smooth animations for data changes.

Regional Sales Reporting

Show sales by region, country, or territory with category axes and colorful series.

Troubleshooting Tips

Chart not rendering:

• Verify AddSyncfusionBlazor() service registration in Program.cs
• Check namespace imports in _Imports.razor
• Ensure script reference is at end of body tag
• Confirm render mode for .NET 8+ projects

Data not displaying:

• Check XName and YName match property names exactly (case-sensitive)
• Verify DataSource is not null and contains data
• Ensure ValueType matches data type (Category for strings, Numeric for numbers)

3D rotation not working:

• Set EnableRotation="true"
• Ensure RotationAngle is between 0-360
• Check if mouse events are blocked by overlays

Performance issues:

• Limit data points (3D rendering is resource-intensive)
• Disable animations if not needed
• Use appropriate chart type for data volume
