1.Add title ,axis Lables, and Legend to Graph:

1 x=linspace(-2*pi,2pi,100);
2 y1=sin(x);
3 y2=cos(x);
4 figure
5 plot(x,y1,x,y2);
6 title(‘Graph of sine and cosine between -2\pi and 2\pi‘);% to display Greek symbols in a title,use the tex markup ‘\‘
7 xlabel(‘-2\pi<x<2\pi‘); % x-axis label
8 ylabel(‘sine and cosine value‘);% y-axis label
9 legend(‘y=sin(x)‘,‘y=cos(x)‘); % add legend

2.change Graph axis Limits functions:

　　Axis function: Axis([xmin,xmax,ymin,ymax]); or xlim([xmin,xmax])/ylim([ymin,ymax])/zlim([zmin,zmax])

3.Change Tick Marks and Tick Labels of Graph:

x=linspace(-10,10,200);
y=cos(x);
figure
plot(x,y)
h=gca; % Use gca to get the handle for the current axes
h.XTick=[-3*pi,-2*pi,-pi,0,pi,2*pi,3*pi];
h.YTick=[-1,-0.5,0,0,5,1]; % Change the location of the tick marks on the plot 
                                       % by setting the XTick and YTick properties of the 
                                       % axes.
h.XTickLabel={‘-3pi‘,‘-2pi‘,‘-pi‘,‘0‘,‘pi‘,‘2pi‘,‘3pi‘};
h.YTickLabel={‘min=1‘,‘-0.5‘,‘0‘,‘0.5‘,‘max=1‘};

Specify tick mark labels by setting the XTickLabel and YTickLabel porperties of the axes, Set these properties using
a cell array of string with the desired labels .If you do not specify enough text labels for all the tick marks,then

MATLAB cycles through the labels.

4. grid on : to display the major grid lines, The grid on command sets the XGrid,YGrid,and ZGrid axes prperties.

5. grid minor: to display the minor grid lines,The grid minor command sets the XMinorGrid/YMinorGrid, and ZMinorGrid properties.

6. grid off : to remove the grid lines,

7.Display Grid Lines in Single Direction:

x=-10:10;
y=x.^2;
figure
plot(x, y);
ax=gca;
ax.XGrid=‘on‘; % setting the XGrid axes property to ‘on ‘ and the YGrid axes property to ‘off‘
ax.YGrid=‘off‘;
ax.XMinorGrid=‘on‘; % setting the XGridMinor axes property to ‘on ‘ and the YGridMinor axes 
ax.YMinorGrid=‘off‘; % property to ‘off‘

 8.Change Grid Line Style:

x=-10:10
y=x.^2;
figure
plot(x,y)
grid on
grid minor
ax=gca;
ax.GridLineStyle=‘-‘;         %change the grid line style using the GridLineStyle and 
ax.MinorGridLineStyle=‘-‘; %MinorGridLineStyle axes properties.
