Matlab GUI communication with Arduino

How would I display the data from a sensor in Arduino to a graph in Matlab GUI where the x-axis is the pc clock or at least in real time? The sensor reading total is three. At the same time I would like to display the data in a static text

Patrick - presumably you have a function that you wish to call that will read your three sensor data values from the Arduino. An example of something similar to this may be found at http://www.mathworks.com/matlabcentral/answers/213364-receive-value-in-matlab-gui.

Now, in your GUI, you can call this function periodically so that you can update the graph and static text values. You can do this by creating a timer. See http://www.mathworks.com/matlabcentral/answers/178682-collecting-a-variable-every-two-minutes for an example of creating a timer within the GUI that periodically collects data which you can then display in the static text boxes and in the axes.

How would I show the different sensor readings from different static text (Note: The three static text would be showed at once) and at the same time it would be updated periodically? Also, I would like to have a push button that would save the plot in the axes into a .mat file.
