save_graph_template

Add another dataset to an existing graph

Add a right-Y layer and plot on it

Add an annotation — kind="referenceline"/"text"/"line"/"arrow"

One-call publication formatting (recommended)

Configure axes — op="labels"/"range"/"scale"/"tick"/"frame"; op="labels" also sets the right/top-axis title on axis="right"/"top"

Apply a palette and/or set the Z color-scale range on a colormapped graph

Create graph (scatter, line, line+symbol, column, bar, area, pie, histogram, box, contour, 3dscatter); optional template= builds it from a saved .otpu/.otp (2D XY types only)

Create a matrix book

Surface (3D), contour, heatmap, or image from a matrix (with a data-linked color scale)

Create new workbook

Curve fitting: parameters ± std errors, R², SSR, reduced χ²; optional plotongraph, xmin/xmax to restrict the fit range, and peaks=N (gauss/lorentz/voigt) for multi-peak deconvolution

Delete a graph window

Export every graph in the project to image files

Export to an image file — raster (png/jpg/tif/bmp) or vector (pdf/eps/emf, resolution-independent); width= sets an exact pixel width for raster (default ~1200px wide, height follows the graph's aspect ratio)

Export a worksheet to CSV/text

Read worksheet data as JSON (empty cells → null)

Import a CSV/text or Excel file (format="auto"/"csv"/"excel"); CSV/text import suppresses Origin's auto-generated sparkline mini-graph windows by default (sparklines=False). filepath may also be a directory or glob to batch-import every matching file, each into its own book

Show available fit functions

List open workbooks, graphs, and matrices

Open existing .opj/.opju file

Add, delete, or edit columns — op="add"/"delete"/"properties"/"formula"

Create new empty Origin project

Remove one data plot from a graph, addressed by index (COM DataPlot.Destroy()) — removes only that plot even if the same dataset is plotted more than once

Execute LabTalk with destructive/file-writing commands blocked; optional capture reads variables back. If a 2+ statement script fails as a whole, it is automatically retried statement-by-statement and each statement's OK/FAILED status is reported (partial application is possible — this is intentiona

Save project to .opju file

Attach Y/X error bars to an existing plot from an error column (no duplicate)

Set font family, size, and optional bold

Set a layer's panel position/size (left/top/width/height)

Configure legend text and position

Set color, line width, symbol shape/size, and open/solid marker

Tick-label numeric format (decimal/scientific/engineering), bold, decimal places, axis→label offset (offsetpct, % of font; +toward axis)

Write column data (JSON arrays)

Sort rows by a column (asc/desc)

Statistics on worksheet columns — op="column"/"comparemeans"/"frequency"

Numerical transform on an XY curve — method="integrate"/"differentiate"/"smooth"/"interpolate"/"fft"/"findpeaks"; smooth takes smoothmethod="savitzkygolay"/"adjacent"/"binomial"

Transpose rows and columns

Break a plot group so each curve can be colored independently

Grid scattered XYZ into a matrix (xyz2mat)
