If I run an automatic extraction it gives "mirrored"results:

What do you mean by "mirrored results"? Mirrored in respect to the abscissa, the ordinate? How do you proceed exactly? Can you replicate e.g. the extraction of the green trace, fourth while counting from right to left, which (replot with gnuplot) then appears to be quite similar?

Out of curiosity, did you rotate the image while making the mask by any chance? I am aware of an open bug that could have possibly caused this: #303

@ankitrohatgi I did not apply a data transformation. What is a bit annoying, however is an other thing: while it is possible to set e.g. a fixed precision and a column separator for the export of single traces digitized, e.g. fixed precision to 5 decimals in total and an explicit white space to separate the columns

02a_single_trace_fixed_precision

is not reflected with the export via click "all datasets" -> export all data. For one, the columns are again separated by commas (one run with sed or awk and there are out of the picture), but the precision defaults back to many more decimals, than wanted:

02b_muli_col_export_fixed_precision

Can future versions of the digitizer please present the data with the number of decimals set in the other (single trace) interface?

The observations refer to the application run remotely from the web address in Firefox (115.5.0esr (64-bit)), the test digitization of all 10 traces attached in the .zip archive below.

@BerendAtEekels A few notes:

  • The archive test.zip as filed December 8th contains a brief silent test.mp4 video how I typically digitize the data using Firefox (at present, version 115.5.0esr (64-bit)) with JavaScript permitted. So far, I did not try the digitizer with the Chrome browser.

  • If you reply to a conversation/issue report here on GitHub, email is valid only if your reply is text only. Any form of attachment will be removed. On the other hand, to substantiate your argument for instance with a .png, a .zip archive ; this only is possible as an attachment in an open session in GitHub itself.
  • Archive 2023-12-08_multi_trace_problem.zip includes file wpd_datasets.csv with all ten traces, labelled 01, 02,...09, 10 beginning with the first trace to the left (light purple, 50 A) digitized with DeltaX = DeltaY = 10 px step width.
