Guide GUI Plot More Data Points

Hi,

I created a guide GUI connected to an Arduino Uno board to plot the Fahrenheit, Celsius, and Kelvin readings from my temperature sensor. When I run the GUI it reads the temperature and shows the data onto the command window, however when it goes to graph the data points only show the temperatures between the first and second-time frame.

function varargout = hello(varargin)
% HELLO MATLAB code for hello.fig
%      HELLO, by itself, creates a new HELLO or raises the existing
%      singleton*.
%
%      H = HELLO returns the handle to a new HELLO or the handle to
%      the existing singleton*.
%
%      HELLO('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in HELLO.M with the given input arguments.
%
%      HELLO('Property','Value',...) creates a new HELLO or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before hello_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to hello_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
