In Matlab App Designer UIAxes doesn´t graph anything.

Hi Everyone, I have a problem with matlab app designer. I'm design a prototype of vibration transductor and i want to design an app to graph in real time the serial data of three axes (X, Y and Z). This serial data come from an ADXL345 and they send from a HC-06 for Arduino (the data are received on COM7).

The bluetooth module, connects correctly, because i configured it to turn on a Led that certified the connection, but The UIAxesX, UIAxesY and UIAxesZ, don't graph anything.

Please post the code.

@Voss I'm sorry, this is the complete code:

THE MODULE IS CONNECTED CORRECTLY BUT THE DATA DOESN'T GRAPH.

Answer 1

Now i changed "STR2DOUBLE" for "str2num" and the X axe graph is ok, the other graphs, don´t received the data
