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:
imgPerformance.zip

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.
Yes, I have downloaded the image already.

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.
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.
Best regards.

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

That one is over 15 years old !
Three visible modules ... done.
Capture, clean in Paint [very quick], save as *.BMP ...
Take Elsid ... Jean

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.

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
The image2rgb() doesn't work with image importing.
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.
Just released a beta version of the Custom Functions plugin for latest Stable SMath Studio. Please test if now it works under linux.
It worked for my linux setup.
Thanks.

... once pixels in hand ► Ksmooth ► final fit.

Tracer is a great tool.
Contact the Author Marcus Karolewski from googling.
You will find his e-mail in case of problem downloading.
In fact, Marcus sent me Tracer 15 years ago.
Also, he is the Author of Spline2XV6. Latest Tracer 2012.
Spline2XV6 was implemented by Mathsoft DAEP on my suggestion.
Jean.
