How to start using the graph widget from touchgfx-open-repository in Touchgfx designer?

[Shake777]

I want to make a graph (let's just use a y = sin(x) function as an example) on my STM32 discovery board. I can make a basic gui from the standard widgets you get when you first run Touchgfx designer and I can add code to make them do stuff as well. I saw no way to add a graph so I googled it and found out you need the graph widget from the repository found here: https://github.com/touchgfx/touchgfx-open-repository

I have downloaded the repository and my question now is how to get the graph widget into TouchGFX designer so I can start coding it to display y = sin(x)? I have a bunch of folders from the repository and the TemplateView.cpp/.hpp files tell you what the individual functions do but not how to get the widget itself into the designer. Apologies if I am missing something obvious here but I could find no clear answers anywhere else.

Yes, everything except the "Graph" run. I have 5 screen and wanted to add one more (the Graph).

Fixed. The CanvasBuffer was too small. Thanks you anyway.

Hello @Martin KJELDSEN​,

Is there a newer version of the GraphApplication project that works with the latest version of TouchGfx 4.13.0?

Thank you in advance

I join the question about the availability of the current version of the GRAPH widget for TouchGfx 4.13.0

Thank you.

Hi,

The graph widget is also implemented in the UI templates "TouchGFX Demo 1" and "TouchGFX Demo 2". You can have a look at how they are implemented.

Hello @Martin KJELDSEN​ , After successful compilation, when I try to run this, it says "No buffer allocated for CanvasWidgetRenderer drawing". Is this similar to @guillaume.1​ in which case, how does one change the CanvasBuffer?

----------------------------

Fixed! So it was associated to the CanvasBuffer afterall. I followed the instructions in this link.
