Plot
2-D Line Plot
Syntax
Plot (y)
Plot (x1, Y1,..., xn, yn)
Plot (x1, Y1, linespec,..., xn, YN, linespec)
Plot (..., 'propertyname', propertyvalue ,...)
Plot (axes_handle ,...)
H = plot (...)

1. Set the coordinate font (A)

Set (GCA, 'fontsize', 12 );

2. Set the x-axis markup text (B)

Xlabel ('frequency (HZ) ', 'fontsize', 14, 'fontname', 'times new Roman ');

Ylabel ('plasma (db) ', 'fontsize', 14, 'fontname', 'times new Roman ');

3. Set the display range of drawing coordinates

Axis ([400 3000-20 70]); % of which 400 3000 is the minimum and maximum values of the X axis;-20 and 70 are the minimum and maximum values of week Y.

4. Set the drawing size.

Set (GCF, 'position', [200 200 350 250]); % Where (200,200) is the coordinate in the lower left corner of the drawing;

% (350,250) is the coordinate in the upper-right corner of the drawing.

5. Mark (C)

Text (0.4, 55,'m = 400,300 ', 'fontsize', 14); % add annotation M = 0.4 at location

6. Set the title (D)

Title ('800hz, sqrt0, 100 ');

7. Set the curve width.

Set (findobj (get (GCA, 'Children '), 'linewidth', 0.5), 'linewidth', 1); % set line width

8. Store drawings

Saveas (GCF, 'test. emf', 'emf'); % the current image is stored as test. EMF.

9. Do not display the drawing

Set (GCF, 'visable', 'off'); % the image is not displayed.

10. annotate different curves in the same drawing

Legend ('m = 100','m = 100 ');

 

E.g.

I,

t1 = (0:11)/11*pi;y1 = sin(t1) .* sin(9*t1);t2 = (0:100) / 100 *pi;y2 = sin(t2) .* sin(9*t2);subplot(2,3,1)plot(t1,y1,'r.')subplot(2,3,4)plot(t2,y2,'r.')subplot(2,3,2)plot(t1,y1,'r')subplot(2,3,5)plot(t2,y2,'r')subplot(2,3,3)plot(t1,y1,t1,y1,'r.')subplot(2,3,6)plot(t1,y1,'g',t1,y1,'r.')
