ReversePlot
This function opens an image file containing a plot. Then the origin, maximum X and Y axis, and data points can be manually and automatically selected to obtain a new vectorial plot (the animated screenshot shows the menus included).
Using Image Processing Toolbox to open idexed and gray images (functions ind2rgb, gray2rgb).

Nice software but logscaling is not working in R2015b

Great code!

Just tried it out and it works simply and well. I like software that doesn't require any reading of manuals, and the results are great. Thanks!

Bug "Delete an area of the curve...:
I think all is needed to correct it is to change line 420 with
rbbox %(no arguments)

Comparing with GRABIT
(http://www.mathworks.co.uk/matlabcentral/fileexchange/7173-grabit):
-Zooming the figure is not possible in reverseplot;
-reverseplot doesn't mark the datapoints manually pointed at, while marking them one by one, only at the end;
-reverseplot does not offer to delete the last point erroneously pointed (could e.g. be bound to Backspace)
-GRABIT misses the automatic curve detection;
Besides, I just realized that in reverseplot "Delete an area of the curve..." has a bug (the selection rectangle is misplaced)
Anyway, both pieces of software are nice and useful.

I see no reason why png should not be supported. To that extent, it is sufficient to change lines 84-90 with:
[filename, pathname] = uigetfile( ...
{'*.jpg;*.jpeg;*.gif;*.bmp;*.tif;*.png','All suported formats'
'*.jpg;*.jpeg','JPEG (*.jpg;*.jpeg)'; ...
'*.gif','Gif (*.gif)'; '*.png','PNG (*.png)'; ...
'*.bmp','Bitmap (*.bmp)'; ...
'*.tif','TIFF (*.tif)'}, ...
'Open scanned image...');

Coooooool. I've found a basic bug, though. In function loaddata, lines 98-100,
info = imfinfo([lower(pathname) lower(filename)]);
[a,map] = imread([lower(pathname) lower(filename)]);
is plainly wrong on a case-sensitive OS like unix, and files with uppercase pathnames won't load. Removing all lower() solves the problem.

Really useful for me.....
I wonder if it's could work on a plot-with-marker like seismic plot.
A very neat bit of code that provides a useful function. Deals with log as well as linear axes. Would be even more useful if it could return the coordinates as data values in the MATLAB workspace.
This is super handy
Really useful !
