Syncfusion.Blazor.Sparkline 34.2.7

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.
