Adxl 335 + arduino + matlab

I am working on a project of connecting an ADXL335 Accelerometer to an Arduino UNO then reading the data in Matlab. So far whenever a reading matlab only show data X-axis.? i hope someone can help
Here is my code :
clear
clc
serialPort = "COM4";
a=arduino();
plotTitle = 'Position AXDL'; % plot title
xLabel = 'Time (s)'; % x-axis label
yLabel = 'Angle (C)'; % y-axis label
legend1 = 'X-Angle';
legend2 = 'Y-Angle';
legend3 = 'Z-angle';
yMax = 180; %y Maximum Value
yMin = -180; %y minimum Value
plotGrid = 'off'; % 'off' to turn off grid
min = -30; % set y-min
max = 30; % set y-max
delay = .01;
time = 0;
data = 0;
data1 = 0;
data2 = 0;
count = 0;
plotGraph = plot(time,data,'-r' ); % every AnalogRead needs to be on its own Plotgraph
hold on %hold on makes sure all of the channels are plotted
plotGraph1 = plot(time,data1,'-b');
plotGraph2 = plot(time, data2,'-g' );
title(plotTitle,'FontSize',15);
xlabel(xLabel,'FontSize',15);
ylabel(yLabel,'FontSize',15);
legend(legend1,legend2,legend3)
axis([yMin yMax min max]);
grid(plotGrid);
tic
while (toc<50) %Loop when Plot is Active will run until plot is closed
vx=readVoltage(a,'A0');
vy=readVoltage(a,'A1');
vz=readVoltage(a,'A2');
[angleX,angleY,angleZ]=VA(vx,vy,vz);
count = count + 1;
time(count) = toc;
data(count) = angleX(1);
data1(count) = angleY(1);
data2(count) = angleZ(1);
%This is the magic code
%Using plot will slow down the sampling time.. At times to over 20
%seconds per sample!
set(plotGraph,'XData',time,'YData',data);
%set(plotGraph1,'XData',time,'YData',data1);
%set(plotGraph2,'XData',time,'YData',data2);
axis([0 time(count) min max]);
%Update the graph
pause(delay);
end
