example 2

The above example showing how change the characteristic of line (like colour, line weight...)

And here is the code:

function shili02

h0=figure('toolbar','none',...

'position',[200 150 450 350],...

'name','example2');

x=-pi:0.05:pi;

y=sin(x)+cos(x);

plot(x,y,'-*r','linewidth',1);

grid on

xlabel('×');

ylabel('Y');

title('y=sin(x)+cos(x)');

function shili02 %this indicate the function's name is shili02

h0=figure('toolbar','none',... %

'position',[200 150 450 350],...%opening a figure window and manipulate the figure

'name','example2');% properties (further detail see example 1)

x=-pi:0.05:pi; %x=-3.14159265, then adding -3.14159265+0.05, continue the adding 0.05 %until x=3.14159265

y=sin(x)+cos(x);

plot(x,y,'-*r','linewidth',1);%plotting x and y but letting the line making of * and red in colour

% and the line width is 1

you can change the '-*r' according to below reference

- solid

: dotted

-. dashdot

-- dashed

(none) no line

o circle

x x-mark

+ plus

* star

s square

d diamond

v triangle (down)

^ triangle (up)

< triangle (left)

> triangle (right)

p pentagram

h hexagram

b = blue

g = green

r = red

c = cyan

m = magenta

y = yellow

k = black

w = white

grid on

xlabel('×'); % labeling X the graph at x axis; you can change the name 'X' to anything you like

ylabel('Y'); %labeling Y the graph at Y axis; you can change the name 'Y' to anything you like

title('y=sin(x)+cos(x)'); %title of the graph, that is y=sin(x)+cos(x)
