This guy uses DrawCircle, but rendering is very slow. The same thing happens if I use DrawPoint.

Hello friends, in this post we have a code to draw a dynamic graph: https://groups.google.com/forum/#!category-topic/mitappinventortest/general-questions-about-app-inventor-programming/fNQVDN-GPIY [142w] I used that code to display a graphic in an application with Arduino and Bluetooth. https://groups.google.com/forum/#!searchin/mitappinventortest/dynamic$20graph|sort:date/mitappinventortest/q-DGa_PVo_o/9yW89uL-BwAJ Now I have simplified the code and show several examples: 1.- Create rand…

Hello friends, this extension is about drawing a dynamic graph, which scrolls to the left. [sin1] in this post we have a code to draw a dynamic graph: Redirecting to Google Groups In this topic I simplified that code and made several examples: Dynamic graph. Sinusoidal wave. Shift left graph Now this extension performs the same effect. Blocks: [extension_graficodinamico15i] You can download the extension from: App Inventor. Extensión. Dibujar un gráfico dinámico. Updated…
