Draw path based on table of co-ordinates. - AmazingGimp - 12-27-2019
Hi there, back again with more challenging graphic, at least for me.
I have a 10,000 points of co-ordinate x-y.
Is there anyway, i can import my points in, and the path start drawing the lines and then interpolate using some polynomial / bezier curve ?
Here is a sample graph, when i plot it in excel.

Try my path-csv script. The CSV should have a specific format, as documented in the link (there are sample ODS+CSV files here). Note that the file is really raw path points, you have to do any required scaling/shift/transformation before exporting to CSV (using your spreadsheet app, for instance). And remember that for Gimp, the Y increase downwards.
This said, 10K points are likely superfluous, a data point per pixel or so is likely enough to have a smooth line.
Otherwise outside of Gimp there are plotting apps.
