Full-stack-skills pencil-ui-design-system-ucharts

Initialize uCharts chart theme tokens and data visualization placeholder frames in a Pencil .pen file. Use when the user mentions Pencil with uCharts or qiun-data-charts, needs to set up chart series colors and axis tokens, or wants to create placeholder frames for Line, Bar, Pie, Radar, and other uCharts chart types.

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
    :
    #1890ff
  • ucharts-color-2
    :
    #52c41a
  • ucharts-color-3
    :
    #faad14
  • ucharts-color-4
    :
    #f5222d
  • ucharts-color-5
    :
    #722ed1

Axis / grid

  • ucharts-axis-color
    :
    #e8e8e8
  • ucharts-text-color
    :
    #666666
  • ucharts-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):

  1. Basic Charts (基础图表)
    • Line, Area, Column, Bar, Pie, Ring, Radar, Scatter
  2. Combined / Advanced (组合与进阶)
    • Mix (mixed charts), Funnel, Candlestick, Heatmap, Gauge, WordCloud
  3. 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_variables
    with
    replace: false
    unless a full reset is requested.
  • Chart "components" here are placeholder frames for layout; actual chart config is code-side.
  • Keep each
    batch_design
    call to maximum 25 operations.
