How to plot two plots in different axes on matlab GUI?

Hello,
Below I have posted my code. My program evaulates a spring mass system by allowing users to input initial conditions along with the mass,spring constant k, any external forces, and any damping present. My program then solves the differential equation and outputs the answer, then I graph the result.
I have also created an animation that involves a spring and a ellipse/circle that mimics an actual spring mass. I have modeled my animation so it moves with respect to the actual equation (sorry if thats a bit unclear). I just figured out how to "draw" my graph out with a for loop (line 195 of my code)(just realized that you cannot see the numbers so the line of code on line 214 is: for i=1:length(time)). And below starting on line 214 I start my loop which draws my animation, and that code starts:for k=V(1):5:length(V)-1 .
The issue I am having is I want both to be graphed/drawn out at the same time, so you could actually see the spring oscillating while the graph is being drawn out. I feel like it would make the presentation much better.
Any help would be appreciated!!!
Thanks, code below:
function varargout = SpringMassP(varargin)
% SPRINGMASSP MATLAB code for SpringMassP.fig
% SPRINGMASSP, by itself, creates a new SPRINGMASSP or raises the existing
% singleton*.
%
% H = SPRINGMASSP returns the handle to a new SPRINGMASSP or the handle to
% the existing singleton*.
%
% SPRINGMASSP('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SPRINGMASSP.M with the given input arguments.
%
% SPRINGMASSP('Property','Value',...) creates a new SPRINGMASSP or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before SpringMassP_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to SpringMassP_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
