Really simple app, but im new to app designer and i don't have much time.

I want to load a 3D matrix with data of a brain in it, and with a slider change the slice plotted.

Thanks in advance

Hi,

You can use the “Slider” Component under “Common” subsection of the “Component Library” in “Design View”.

The “Slider” component has two callBack functions that you can use.

“SliderValueChanging(app, event)” callback function when you want to execute some functionality as and when the Slider is moving ( or the Slider Value is Changing)
“SliderValueChanged(app, event)” callback function when you want to execute some functionality when Slider position has changed.

If you would like to learn more about CallBack functions you can check here

Hi, Sourabh Kondapaka

I already figured out how to draw 2D image with app deigner, but I still wonder how I can show a 3D volumetric data with app designer. Is there any valid reference? Thank you so much!
