uCharts Design System Initializer
Constraint: Only use this skill when the user explicitly mentions "Pencil" and "uCharts" (or "qiun-data-charts") or when orchestrating a Pencil design system initialization task for charts.
When to use this skill
Use this skill when:
- The user wants to initialize uCharts chart theme tokens (series colors, axis, text) in a Pencil .pen file
- The user needs placeholder frames for uCharts chart types (Line, Area, Column, Bar, Pie, Ring, Radar)
- The user mentions "Pencil" together with "uCharts", "qiun-data-charts", or chart visualization components
- An orchestrator skill (pencil-ui-designer) routes a uCharts initialization request
How to use this skill
This skill outputs a PENCIL_PLAN. The Agent then calls Pencil MCP tools in order: open_document, set_variables, batch_design, optionally get_screenshot.
Step 1: Initialize Variables (set_variables)
Use mcp__pencil__set_variables to register uCharts-related design tokens (chart theme colors, font). Follow .pen file schema.
Chart colors (series)
ucharts-color-1:#1890ffucharts-color-2:#52c41aucharts-color-3:#faad14ucharts-color-4:#f5222ducharts-color-5:#722ed1
Axis / grid
ucharts-axis-color:#e8e8e8ucharts-text-color:#666666ucharts-font-size:12px
Fill from uCharts theme docs if more tokens are needed.
Step 2: Create Component Overview Structure (batch_design)
Use mcp__pencil__batch_design to create a "Charts Overview" frame with placeholder sections for chart types (data-viz components):
- Basic Charts (基础图表)
- Line, Area, Column, Bar, Pie, Ring, Radar, Scatter
- Combined / Advanced (组合与进阶)
- Mix (mixed charts), Funnel, Candlestick, Heatmap, Gauge, WordCloud
- Containers (容器)
- Chart container placeholder, Legend placeholder
Organize frames using Auto Layout. Keep each batch_design call to maximum 25 operations.
Example: Initialize uCharts Variables
{
"name": "set_variables",
"arguments": {
"filePath": "designs/dashboard.pen",
"replace": false,
"variables": {
"ucharts-color-1": "#1890ff",
"ucharts-color-2": "#52c41a",
"ucharts-color-3": "#faad14",
"ucharts-color-4": "#f5222d",
"ucharts-axis-color": "#e8e8e8",
"ucharts-text-color": "#666666",
"ucharts-font-size": "12px"
}
}
}
Best Practices
- Verify token values against uCharts theme documentation.
- Use
set_variableswithreplace: falseunless a full reset is requested. - Chart "components" here are placeholder frames for layout; actual chart config is code-side.
- Keep each
batch_designcall to maximum 25 operations.
