Chart Style Unifier

When to Use

• Use this skill when you need batch-unify typography (font family, size, italics) for word table cells and embedded charts; use when you need consistent formatting across theses/reports without changing body text in a reproducible workflow.
• Use this skill when a others task needs a packaged method instead of ad-hoc freeform output.
• Use this skill when the user expects a concrete deliverable, validation step, or file-based result.
• Use this skill when scripts/change_table_font.py is the most direct path to complete the request.
• Use this skill when you need the chart-style-unifier package behavior rather than a generic answer.

Key Features

• Scope-focused workflow aligned to: Batch-unify typography (font family, size, italics) for Word table cells and embedded charts; use when you need consistent formatting across theses/reports without changing body text.
• Packaged executable path(s): scripts/change_table_font.py plus 2 additional script(s).
• Reference material available in references/ for task-specific guidance.
• Structured execution path designed to keep outputs consistent and reviewable.

Dependencies

• Python: 3.10+. Repository baseline for current packaged skills.
• Third-party packages: not explicitly version-pinned in this skill package. Add pinned versions if this skill needs stricter environment control.

Example Usage

cd "20260316/scientific-skills/Others/chart-style-unifier"
python -m py_compile scripts/change_table_font.py
python scripts/change_table_font.py --help

Example run plan:

1. Confirm the user input, output path, and any required config values.
2. Edit the in-file CONFIG block or documented parameters if the script uses fixed settings.
3. Run python scripts/change_table_font.py with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

Implementation Details

• Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
• Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
• Primary implementation surface: scripts/change_table_font.py with additional helper scripts under scripts/.
• Reference guidance: references/ contains supporting rules, prompts, or checklists.
• Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
• Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

1. When to Use

• You need to normalize table cell fonts across a Word document (e.g., thesis tables must use SimSun 10pt).
• You have many embedded Word charts and want consistent typography (title/axis/ticks/legend/data labels) without manual editing.
• You are preparing a final submission/export (PDF/print) and want to eliminate inconsistent chart/table styling.
• Your document contains mixed chart types (with/without titles/legends) and you need a robust batch operation that won’t fail on missing elements.
• You have linked charts and want a safe workflow: unify styles in the Excel sources first, then refresh in Word.

2. Key Features

• Word table-only processing: updates typography inside table cells only; does not modify body text styles.
• Embedded chart typography normalization (VBA):
  • Chart area base font
  • Chart title
  • Axis titles
  • Tick labels
  • Legend
  • Data labels
• Config-driven Python workflow: initialize a run directory, edit a generated config.json, then execute.
• Run isolation: outputs are written to outputs/runs/<timestamp>/ for traceability.
• Linked chart guidance: highlights that Word-side changes can be overwritten by Excel link refresh.

4. Example Usage

4.1 Unify Word Table Cell Fonts (Python, runnable)

# 1) Initialize a run directory for table processing

4.2 Unify Embedded Chart Typography (Word VBA, runnable)

Paste into Word VBA Editor (Alt+F11) and run NormalizeChartTypography:

Option Explicit

Public Sub NormalizeChartTypography()
    Dim fontName As String
    Dim baseSize As Single, titleSize As Single
    Dim axisTitleSize As Single, tickLabelSize As Single
    Dim legendSize As Single, dataLabelSize As Single

    fontName = InputBox("Font Name", "Unify Chart Fonts", "Times New Roman")
    baseSize = CSng(InputBox("Base Size (ChartArea)", "Unify Chart Fonts", "9"))
    titleSize = CSng(InputBox("Chart Title Size", "Unify Chart Fonts", "11"))
    axisTitleSize = CSng(InputBox("Axis Title Size", "Unify Chart Fonts", "9"))
    tickLabelSize = CSng(InputBox("Tick Label Size", "Unify Chart Fonts", "8"))
    legendSize = CSng(InputBox("Legend Size", "Unify Chart Fonts", "10"))
    dataLabelSize = CSng(InputBox("Data Label Size", "Unify Chart Fonts", "8"))

        If ish.HasChart Then
            ApplyChartTypography ish.Chart, fontName, baseSize, titleSize, axisTitleSize, tickLabelSize, legendSize, dataLabelSize
        End If
    Next ish

    For Each shp In ActiveDocument.Shapes
        If shp.HasChart Then
            ApplyChartTypography shp.Chart, fontName, baseSize, titleSize, axisTitleSize, tickLabelSize, legendSize, dataLabelSize
        End If
    Next shp

    Application.ScreenUpdating = True

4.3 Unify Linked Chart Source Files (Excel VBA, runnable)

Run in Excel on the source workbook(s) before refreshing links in Word:

Option Explicit

Public Sub NormalizeLinkedChartTypography()
    Dim fontName As String
    Dim baseSize As Single, titleSize As Single
    Dim axisTitleSize As Single, tickLabelSize As Single
    Dim legendSize As Single, dataLabelSize As Single

    fontName = InputBox("Font Name", "Unify Chart Fonts", "Times New Roman")
    baseSize = CSng(InputBox("Base Size (ChartArea)", "Unify Chart Fonts", "9"))
    titleSize = CSng(InputBox("Chart Title Size", "Unify Chart Fonts", "11"))
    axisTitleSize = CSng(InputBox("Axis Title Size", "Unify Chart Fonts", "9"))
    tickLabelSize = CSng(InputBox("Tick Label Size", "Unify Chart Fonts", "8"))
    legendSize = CSng(InputBox("Legend Size", "Unify Chart Fonts", "10"))
    dataLabelSize = CSng(InputBox("Data Label Size", "Unify Chart Fonts", "8"))

    Application.ScreenUpdating = False

    Dim ws As Worksheet, co As ChartObject
    For Each ws In ActiveWorkbook.Worksheets
        For Each co In ws.ChartObjects
            ApplyChartTypography co.Chart, fontName, baseSize, titleSize, axisTitleSize, tickLabelSize, legendSize, dataLabelSize
        Next co
    Next ws

    Application.ScreenUpdating = True
End Sub

5. Implementation Details

5.1 Processing Scope and Constraints

• Allowed input: only the Word document path explicitly provided by the user (target_doc_path).
• Output directory: outputs/runs/<timestamp>/.
• Disallowed access: parent traversal (../) and sensitive system directories.
• No network usage: local-only operations; no external APIs; no credentials.

5.2 Python Table Unification Logic (Conceptual)

• Reads outputs/runs/<timestamp>/config.json.
• Opens the .docx and iterates tables → rows → cells → paragraphs → runs.
• Applies:
  • font_name and font_size to runs inside table cells.
  • Optional toggles (if enabled in config): italics rules for numbers/Chinese/lowercase letters.
• Saves results into the run output directory (implementation-dependent).

5.3 Chart Typography Tokens (What Gets Normalized)

Recommended parameter mapping (used by the VBA macros):

Element	VBA Target	Parameter
Chart area base	Chart.ChartArea	baseSize
Chart title	Chart.ChartTitle	titleSize
Axis titles	Axes(...).AxisTitle	axisTitleSize
Tick labels	Axes(...).TickLabels	tickLabelSize
Legend	Chart.Legend	legendSize
Data labels	Series.DataLabels	dataLabelSize

5.4 Linked Charts: Overwrite Behavior

• If a chart in Word is linked to Excel, refreshing the link can overwrite Word-side formatting.
• Safe workflow:
  1. Normalize chart typography in the Excel source files (Excel VBA).
  2. Refresh/update links in Word.
  3. Only use Word VBA for charts that are truly embedded (not linked).
