Hi Franco. Thanks, but exceptional is SMath in general, and XYPlot plugin in particular. Hope these notes can help to read the procedure for drawing text in this way.

Alvaro, Oscar,

I am going ahead in the Callout project but I have reached a critical point and I am struggling hard ..but do not find a possibility to progress and complete it as I would like.
I was able to create the callout drawing, to word wrap the text in different rows and to convert the rows in BMP strings and to store them in a vertical array ( Alvaro I didn't create a block with all these rows merged togheter as in your program I decided to keep them split ) .
Now i need to apply the instructions to draw them in the XY Plot Region ...and here comes the troubles.
I am not able to create a loop to do this because in this type of instruction :



the image file/name ( i.e. "image:{BMPxCallout1}" )can't be retrived from an array of images and I can't write directly "el(TxtxCallout,i_rows)" , (sorry but I don't know how to write the corresponding indexed variable in this post so I left the internal representation ) but I need to transit through the assigment of that element to a variable not indexed.

I am running through the posts related to creating traces in a loop from Oscar and Martin ..but I am not able to cume up with a solution/workaround .

Any suggestion will be highly appreciated; thanks in advance for any help, take care and best regards.

Franco

Herewith the files I am working actually, you can see the terrible ways used to draw/test something

XYPlot - Callout_with_Scalable monospaced BMP fonts.sm (2,144kb) downloaded 2 time(s). SubmtrxChrRef.xlsx (14kb) downloaded 1 time(s).

Alvaro thank you very much indeed for your help and all the other valuable informations in the excel file re-attached to yout post .
I have had always the illusion to be a Lotus 123 and then a MS Excel superuser ...but I was never aware of the camera tool so have been shocked to see it applied in your spreadsheet.

Moreover to tell the truth I have tried by myself to play with the concat and the str2num a num2str commands feeling that using these commands there was the possibility to solve the issues that I was facing ..but I started to think too much; the desire was to create a variable name (continuouly changing with an index) on the left side of an assignment expression and assign to it the content of an indexed variable . You see herewith the initial attempts but I give up quite soon seeing errors from Smath ( but obvously it was a fault of mine due to my ignorance )


However now thanks again to your help will try to arrive at an initial release for the Callout project/functions hopefully.

Take care and best regards.

Franco

Oscar ,

thanks a lot - as usually - for the examples and the clarity of the explanation.

Best regards

Franco

Hi Franco. I guess that the problem is that the image tag {img} must be at the worksheet level. Please check the note at the right margin in the file from this post: https://en.smath.com/for...ot-Region.aspx#post86128

Images are matrices. You can unlink them from the file showing the matrices with an evaluation, x = ..., expanding the view to the entire matrix, and making a further assignation with x : ... with the most valuable code in windows: copy and paste.

Best regards.
Alvaro.

Hi Franco
Finally I have a time to check your file and here are the answers and solutions to your questions.

In the attached file...
1. I explain how to obtain the "Arial Matrix" using the magical recipe "copy and paste"
2. How to deal with local variable defined inside a function and pass it to the "worksheet level" (as mention Alvaro)

All my answers and commentaries are in yellow font and black background

My best wishes,

Oscar

Ok Franco. You are getting the idea.
Te best way to understand and realize things like those ones is read the documentation and stay alert to this forum. There are many interesting topics and discussions and you can learn new things from people working on different problems and projects.
In fact, some monts ago I learned another way to redefine worksheet vars from functions, (please check this post)

So when you apply this technique you can solve your problem in a more elegant way, as I show in the following file.

Hi Team,
after a long time I guess that I was able to develop a 1st release of the Callot project that I attach herewith. XYPlot - Callout_with_Scalable monospaced BMP fonts_Ver1.sm (1,826kb) downloaded 0 time(s).
I hope that this can be of any help for someone who needs to add callouts to drawings.
The shape of this release is not what I would like and I plan to add the following:

0-Add the trasparency in each row of text as shown in an Alvaro's example about this issue.

1-Add the BMP fonts available in the file of Alvaro and some additional ones similar to the style of a text in Autocad (need to check where I can find them because there aren't in Excel)

2-Check if make sense do not introduce the coordinate of the arrow part of the callout as arguments of the final function used for their drawing ( I guess that is not a very good idea )

3-Moreover I would like to minimize the Inputs for the creation of a callot using the method seen in some examples from UNI related to Shapes drawing ( basically defining defaults that can optimize the graphical look of the callout so that if some inputs are missing these defaults are used )

Again I would like to acknowledge the enormous help of Alvaro and Oscar who with their examples and suggestions allowed me to move forward with this project(probably the word project is too important for what I did that is something very modest).

Last thing is related to the copy and past technique use to store a font matrix ( or other data ) in a worksheet avoiding to retrive these data each time from an external data file.
Now the procedure explained works ..but not in a nice way ; I mean that if I have a huge matrix of data read from an external Excel file for instance I see that this matrix is displayed with 3 dots at the bottom that allow to see the matrix in a collapsed way . The problem rises when I want to copy the content of this matrix in another variable . First this is NOT possible if I don't expand all the matrix so that I can see and select ALL the data that are stored in it . Second most annoying thing is that after the copy and past in the new storage variable it is no more possible to collapse the structure of the matrix using the 3 dots and I must see it as a whole forever .
My personal opinion is that this behaviour is not correct and that it is very similar to a bug.

For what concern the callout function I am obviosly available for any suggestion for improvements and to critics or requests for clarification ( I tried to document as much as possible the main variables/parameters used but this was based on my personal point of view )

Best Regards

Franco
