Couldn't make it work with linux.
Will check with a windows machine.
Yet, if I understood what it does...
WOW, this is sick. How is it possible?
I am just simply amazed by this.
Very good job.

Hi overlord. Thanks. Do you download the image "imgPerformance.jpg" and put it in the same directory than the sm file? It is the only issue specific for linux that I can see. I know, it is showed instead given the link for download. Here it is as zip file:

Yes, I have downloaded the image already.
It starts to give error on Ms:scan(Mc,k1,255)
`Argument doesn't meet to expected kind`.
Perhaps the image2rgb doesn't work under linux.
M matrix is filled with zeros, nothing else.

Hi. I remember now that the worksheet also use Mean, from statics plugin, and I put it definition at left margin, but disable. Maybe it's that one. This version have embed image matrix, and except for the XYPlot, I guess that it have not any other plugin.

I have statistical plugins with linux.
In windows, with same plugins and setting it solve.
And matrix is not full of zeros.
image2rgb is not working under linux.

Try this suggestion:
1. Plug one of those dirty image in Paint.
2. zap the X,Y grids.
3. Capture WinGrab and note the X, Y pixels for further scaling.
4. Insert picture, Digitize, clean ... finish project.

OMG,
I may try to rehash an old problem that Jean helped me with in MathCAD that I could never get to work.
First, why the error in the SM file? I just downloaded and opened using Portable version on both Windows 10 and Linux.

Hi. You can try to eval only Ms outside the plot for read the error, if it is not an specific error related with the plot.

Best regards.

Ms is not defined. As you can see, I changed kc as well.

Nope. The message says that "M" is not defined, not Ms. And M is for load the image, not for doing some process. Try this version, with the image embeded in the worksheet:

https://en.smath.com/forum/yaf_postsm71146_Approximation-of-a-functional-curve-in-a-digital-image.aspx#post71146

and check if you can update the plugins for images.

Best regards.
Alvaro.

I have tried the embedded image version with linux (not portable).
The image2rgb() doesn't work with image importing. But image data matrix embedded version works fine.
If image data added version don't work for you, Maybe the portable plugins are old and not suitable.

Regards

Elsid,
My offer via Paint is valid, but delicate from too thick graph.
My other tool is via Tracer 15 [freeware]
Paste image as is in Tracer, capture at will pixels.
Each capture is stacked in vector, obviously noisy.
Once in hand, Ksmooth the Y vector ...
We have Ksmooth as a Smath utilities.
Once smoothed, spline ... Job done.
Have a good day ... Jean

image2rgb has a procedure for fast image reading that somehow doesn't works in mono

I'll try to update a beta version with an alternative code ASAP.
