Usage
/chart-export {format}
Arguments
format(required): Output format - one of: png, svg, pdf
Examples
/chart-export png
/chart-export svg

Tool Mapping
This command uses the chart_export MCP tool:
chart_export(
figure=figure_json, # Plotly figure JSON from chart_create
format="png", # Output format: png, svg, pdf
width=1200, # Optional: image width in pixels
height=800, # Optional: image height in pixels
scale=2, # Optional: resolution scale factor
output_path=None # Optional: save to file path
)
Workflow
- User invokes:
/chart-export png - Agent asks: Which chart to export? (if multiple charts in context)
- Agent asks: Image dimensions? (optional, uses chart defaults)
- Agent exports: Chart with
chart_exporttool - Agent returns: Base64 image data or file path
Output Formats
| Format | Best For | File Size |
|---|---|---|
png |
Web, presentations, general use | Medium |
svg |
Scalable graphics, editing | Small |
pdf |
Print, documents, archival | Large |
Resolution Options
Width & Height
Specify exact pixel dimensions:
chart_export(figure, format="png", width=1920, height=1080)
Scale Factor
Increase resolution for high-DPI displays:
chart_export(figure, format="png", scale=3) # 3x resolution
Common scale values:
1- Standard resolution (72 DPI)2- Retina/HiDPI (144 DPI)3- Print quality (216 DPI)4- High-quality print (288 DPI)
Output Options
Return as Base64
Default behavior - returns base64-encoded image data:
result = chart_export(figure, format="png")
# result["image_data"] contains base64 string
Save to File
Specify output path to save directly:
chart_export(figure, format="png", output_path="/path/to/chart.png")
# result["file_path"] contains the saved path
Requirements
This tool requires the kaleido package for rendering:
pip install kaleido
Kaleido is a cross-platform library that renders Plotly figures without a browser.
Error Handling
Common issues:
- Kaleido not installed: Install with
pip install kaleido - Invalid figure: Ensure figure is valid Plotly JSON
- Permission denied: Check write permissions for output path
