Data Processing

Exporting and Presentation

Origin provides many options for exporting and presentation, from sending graphs to PowerPoint, to creating movies

Resize Graph for Publishing


Journals typically require a specific width for the graph image, such as 86 mm for single column and 178 mm for double column. In addition, at the scaled size, they may require text labels to be above a particular font size, and lines to be above a certain thickness.


In this version, we offer the following key features for preparing the Origin graph with the exact width specification:

  • Resize graph page by specifying desired width, while maintaining aspect ratio (auto scale height when width is changed)
  • Scale all elements on the page when resizing in order to maintain proportional balance in the graph
  • Conversely, set element scale to some fixed factor when you want to maintain absolute size of elements
  • Fit all graph layers to the available page area using user-specified margins, while maintaining layer relationships, relative size, and object scale


Once the graph has been scaled to the desired width then it can be exported in a vector or raster format for submission to the journal.

image

image

Specify desired width and units to match requirements of the journal. The page height will be proportionally scaled while maintaining aspect ratio. Relative dimensions of all objects in graph will be maintained.

image

Reduce white space in your graph page by either expanding all layers to occupy available space (Fit Layers to Page) or by reducing page size (Fit Page to Layers).
