interpolation in graphics

Good afternoon friends of the community, I am new to using Mathcad. I have a problem getting data from a general graph for an area smaller than the interior as shown in the graph. My version of Mathcad Prime is V.9.0

 

Thank you for your attention.

interpolacion en graficos

Muy buenas tardes amigos de la comunidad, soy nuevo en el uso del mathcad. Tengo un problema en la obtención de datos a partir de un grafico general para un área menor al interior como se muestra en el grafico. Mi versión de mathcad Prime es V.9.0

I don't speak Spanish and (like you) I am too lazy to fire up a translator.

But in case you are looking for interpolation as you had written in the thread subject, you could do it that way:

Its not clear to me what exactly you are looking for.

Are you just interested in the very same calculation but with different input values A and B?

If yes, you may consider turning the calculations into functions with arguments A and B.

Good morning, the problem I have is that the new values ​​obtained with "a" and "b" are greater than the values ​​found in the corners of the larger rectangle. What I want to do is obtain the values ​​at the points considering the values ​​of the large rectangle, because 104,467, 124,909, 81,603 and 102,046 tonneph/m are greater than the limits of the rectangle 18,323, 19,652, 22,335 and 21,005 tonneph/m.

Muy buenos días, el problema que tengo es que para los nuevos valores obtenidos con "a" y "b" son mayores a los valores que se encuentran en las esquinas del rectángulo mayor, Lo que deseo hacer es obtener los valores en los puntos considerando los valores del rectángulo grande, por que

If I remember correctly, the much-missed Mathcad Picture Operator allowed one to select a region of an image and return a vector(?) of the coordinates of the corners of the selection (and possibly the corresponding image data; my memory’s hazy on that bit)

 

That might have proved useful in cases such as this for approximating an area of interest. 

If I further recall correctly, I used this information to update the Picture Operator. One could, as I mentioned recently, use the PO as a function and pass in image updates via an argument.

 

Given the number of worksheets that made use of its capabilities, I am surprised that the Picture Operator hasn’t made it further up the PTC priority list.

 

Not being able to automatically display/update a generated/processed image in Mathcad is frustrating beyond measure.

Thank you very much dear Werner_E, that is indeed what I was trying to achieve. Abusing your kindness, and if my input data were in the form of a matrix as I show you below, what would be the procedure? Excuse my boldness, the truth is I am just starting to use Mathcad Prime.

 

Thank you for your attention

Muy agradecido estimado  Werner_E,  efectivamente es lo que estaba tratando de conseguir. Abusando de su amabilidad, y si mis datos de entrada sean en forma de matriz como le muestro a continuación 

DC_11916766_0-1726262500013.png

como seria el procedimiento, Disculpe el atrevimiento la verdad estoy empezando a utilizar el mathcad Prime. 

Gracias por la atención
