Export overview#

Select Export in the header to choose an output format. Exporting produces a new file from the current project; it does not replace the editable .graphx project or change its source data. The Export action is available once an image or project is loaded.

Choose an output#

  • CSV data is the best choice for numerical work in a spreadsheet, calculation package, or another data-analysis tool. It can contain multiple datasets as adjacent X/Y column pairs.
  • Copy data is a quick active-dataset action in the Data points drawer. It copies tab-separated values that paste naturally into spreadsheet columns.
  • PDF report is for review, sharing, or a record of a digitisation. It combines the source graph, points, data tables, calibration context, project notes, and selected trendline results.
  • JPEG image is for an annotated visual image. It starts from the source image at its original dimensions and adds exported dataset point markers and labels.

Use CSV and copied data when you need the exact tabular structure, PDF reports for a complete report, and JPEG export for an annotated image.

Export checkboxes#

Each dataset has an Export checkbox in the Datasets list. It controls whether that dataset is included in CSV, the raw dataset content of a PDF report, and JPEG point overlays. Clearing the checkbox does not hide, delete, or make the dataset uneditable in GraphX.

Trendlines have their own Export checkbox. This affects PDF reports only and is separate from whether the line is currently visible on the graph. Trendlines are not written to CSV and are not drawn in JPEG export. Keep the source dataset enabled for export as well: the current report generation receives enabled datasets as its report data, so an unchecked source dataset cannot contribute its trendline result to the PDF.

The active dataset's Copy data action is intentionally independent of its Export checkbox. It copies that dataset when it has calibrated points, which is useful for checking or pasting a dataset that is temporarily excluded from file exports.

Precision and names#

Dataset Precision controls the presentation of point coordinates in CSV, copied TSV, PDF tables, and the Data points table. It formats displayed/exported text; it does not recalculate or round the stored point geometry.

Trendlines have separate coefficient precision for their equations and results in the interface and PDF. Dataset precision does not alter those fitted coefficients.

Generated filenames retain a readable project-name prefix, sanitising only filename-problematic characters. They use the browser's local save time in YYYY-MM-DD HHMMSS form:

Solubility study - Data - 2026-09-19 202843.csv
Solubility study - Report - 2026-09-19 202843.pdf
Solubility study - Image - 2026-09-19 202843.jpg

Browser delivery#

Desktop browsers normally download generated files. On iPhone and iPad, GraphX uses the native share/save flow rather than navigating the current application tab to a generated file. CSV data can usually open the share sheet directly from Export. PDF and JPEG generation is asynchronous, so GraphX may first say that the file is ready and offer a second Save action; use that action to open the native share/save sheet. Cancelling a share sheet is not treated as an export failure.

Project saving follows the same Apple-mobile pattern; see Saving and opening projects.
