How to plot multiple lines in the same graphics using GUI?

조회 수: 10(최근 30일)
I was trying to plot a graphics of 'c vs X' for different 't'(t1,t2,t3 etc) in the same graph using GUI. Note that, lines for different t should be plotted one by one (i.e after plot of line 1 (t1), it will wait for input of t2 to plot line 2 and so on).Is there anybody to help in doing that? Thanks in advance !
MY CODE IS:
function varargout = gui_trail(varargin)
% GUI_TRAIL MATLAB code for gui_trail.fig
% GUI_TRAIL, by itself, creates a new GUI_TRAIL or raises the existing
% singleton*.
%
% H = GUI_TRAIL returns the handle to a new GUI_TRAIL or the handle to
% the existing singleton*.
%
% GUI_TRAIL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI_TRAIL.M with the given input arguments.
%
% GUI_TRAIL('Property','Value',...) creates a new GUI_TRAIL or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before gui_trail_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to gui_trail_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Your draw callback always creates a new figure and then plots in to that. You should instead do something like
ah = findobj(0,'Type','axes','Tag','MyPlotAxes');
if isempty(ah)
fh = figure;
ah = axes('Parent',fh, 'Tag', 'MyPlotAxes');
hold(ah, 'on');
end
plot(ah, x, c(x));

Hello Mr. Roberson,
Need your help once agin. Could you please tell me how to solve that-below ?
I want to put different legend for each t (t1,t2 etc)with different color or may be shape (legends should be autometically generated).
Thanks in advance.
