extract data from figure

HI, I am extarcting data from a THD figure in matlab.

The following is the code that i used. I am getting only 600 values of x-axis. but my figure has 15000 values at x-axis.

I request you to help me. I have attached the file.

clear all;
close all;
clc;
fig=openfig('vmpcnew1thd.fig');
dataObjsY = findobj(fig,'-property','YData');
y1 = dataObjsY(1).YData;
y2 = dataObjsY(2).YData;
dataObjsX = findobj(fig,'-property','XData');
x1 = dataObjsX(1).XData;
x2 = dataObjsX(2).XData;

Thanks and regards,

Sivakumar

*.fig file are basically *.mat files. You can try following in order to extract data from *.mat files

plot(rand(100,1)); % create a plot
hold on;
plot(2*rand(100,1));
hgsave(gcf,'vmpcnew1thd'); % saving a plot to a figure
data_extract = load('vmpcnew1thd.fig','-mat'); %load data to workspace
X1 = data_extract.hgS_070000.children.children(1).properties.XData; % reading xdata
X2 = data_extract.hgS_070000.children.children(2).properties.XData;  
Y1 = data_extract.hgS_070000.children.children(1).properties.YData; %reading y data
Y2 = data_extract.hgS_070000.children.children(2).properties.YData;

Hi, I need the variables in the workspace. But I cannot see the values anywhere. Could you please guide me where can get xdata and ydata. Also the figure shape is changed.
