Hello all,
Is there a feature in SNOWIRT to generate and visualize more than one expected score curve at the time? It seems the software allows viewing only one curve, which makes exporting each curve individually quite time-consuming when working with large item sets.
If such a feature already exists, I haven’t been able to locate it, and would appreciate any guidance.
If not, I’d love to hear any tips or workarounds from the community. Would this be a possible feature to add?
Thanks!

Hi
Implementing the feature to display a separate graph for each item requires a fundamental change to the module's structure. The output for plot must be converted from a single plot object into a dynamic array of plots.
This change affects more than just the plotting function itself:
Initialization: The setup process must be adapted to handle an array of plots rather than a single one.
Data Preparation: A new procedure is needed to loop through all selected items and assign the correct data to each corresponding plot in the array.
Rendering: The final rendering function must be aware that it is part of this array system to draw the correct graph for its specific data.
In short, creating an array of plots is a more complex task than creating a single plot, requiring coordinated changes across multiple parts of the code to ensure stability and proper function. The difficulty arises from this necessary structural complexity.

Thank you for your answer. I understand the complexity — it was worth a shot 
. All the best!

Hi Belzile
Good news.
All graphs are produced simultaneously when you select the analysis option in dichotomous and polytomous model.
The updated version will be available on Monday. I will let you know. Thanks for your request again.
