Syncfusion.Blazor.Sparkline

Syncfusion Blazor Sparkline Charts

The Syncfusion Blazor Sparkline Component displays lightweight, single-series data visualizations in a compact cell or inline format. Perfect for dashboards and data summaries, sparklines show trends at a glance without axis labels or legends.

Using this package with an AI coding agent

Before generating Syncfusion code, ask your AI coding agent to run the Syncfusion setup using the following prompt:

Set up this project for Syncfusion before generating code. Fetch and follow the official instructions at https://ai.syncfusion.com, then report the detected platform, installed skill pack, MCP status, and any required licensing action.

The setup detects your project's platform and loads the appropriate Syncfusion skill pack. No Syncfusion account or MCP key is required to install or read Syncfusion agent skills.
