MATLAB | the old version can also be used, and the default setting allows simple code to draw cool images

Examples:

There was an issue of cool drawing background code before, but there are several problems:

The old version can't be used, and it needs to be relatively new to support my fancy writing. The general description should be a structural function containing an indefinite parameter list of anonymous functions and callback functions...
Just decorate the background, and the attributes of graphic objects such as lines and scatter points need to be decorated by yourself.
It is too troublesome to run the tool function every time.

Then this article will be solved all at once!

Train of thought (can be omitted)

Let's write a code to draw a broken line, and the effect is as follows:

t=0.01:0.01:3*pi;
plot(t,cos(t)./(1+t))
hold on
plot(t,sin(t)./(1+t))
plot(t,cos(t+pi/2)./(1+t+pi/2))
plot(t,cos(t+pi)./(1+t+pi))
legend

But if we run this sentence casually in an m file or a command-line window:

set(groot,'defaultLineLineWidth',2)

After that, as long as you use the plot or line function to draw a picture and do not set the line width, the lines drawn will be thickened and the thickness will be 2. The previous line of line drawing code will not move and the effect will be directly run:

This is to directly set the default value for the root graphic object (the lowest graphic object in MATLAB). Let's see that 'defaultlinewidth' is actually

default + Line + LineWidth

It is very simple to set the default value of the linewidth of the line object (Line). Similarly, if I want the background to be black every time I draw a picture, I only need to run one sentence:

set(groot,'defaultAxesColor',[0,0,0])

In the future, the background is black.

Introduction to tool functions

So I wrote a function selfGrootDefault(theme) tool that can be decorated with basic graphic objects and backgrounds. The function is too long and will be put at the end. Let's explain the usage first:

For example, I run it in an m file or a command line window:

selfGrootDefault(4)

Or:

selfGrootDefault('dark2')

The above two lines refer to the same decoration method (for the convenience of each style, a number is set, which can be directly used to call). After that, you can write some functions to draw some pictures, and the effect is not very straight. The original drawing:

surf(peaks)
set(gca,'Projection','perspective')
view(-37,42)

y=[2 2 3; 2 5 6; 2 8 9; 2 11 12];
bar(y)

To change back to the default settings, just run

selfGrootDefault(0)

At this time, the same code runs again and draws the original drawing:

Style display

Unmodified basic painting effect:

subplot(2,2,1)
t=0.01:0.01:3*pi;
plot(t,cos(t)./(1+t))
hold on
plot(t,sin(t)./(1+t))
plot(t,cos(t+pi/2)./(1+t+pi/2))
plot(t,cos(t+pi)./(1+t+pi))
legend

subplot(2,2,2)
axis([0,50,0,50,-10,10])
xticks(0:10:50)
yticks(0:10:50)
zticks(-10:5:10)
hold on
surf(peaks)
set(gca,'Projection','perspective')
view(-37,42) 

subplot(2,2,3)
t=linspace(pi/100,4*pi,500);
y1=cos(t).^2;
y2=sin(t).^2./t;
hold on
area(y1)
area(y2)

subplot(2,2,4)
y=[2 2 3; 2 5 6; 2 8 9; 2 11 12];
bar(y)

The following values represent the code:

selfGrootDefault(n)

What is n in

1 / 'gbase'

2 / 'gbase2'

3 / 'dark'

4 / 'dark2'

5 / 'ggray2'

6 / 'economist'

7 / 'wsj'

an account of happenings after the event being told

Many of my programs need 17b later, and even some need 19b later. It's generally smoother to run my programs with the latest version of MATLAB, but I can't completely rely on the version limit. I also want to take care of most versions so that all versions of the code can be used, but some functions will be abandoned in the future, and some writing methods will not be used in the future. I can't write codes waiting for depreciation. Secondly, many new functions are too easy to use, Therefore, it's better for Amway to check the new version (although there should be no version limit in this push!)

The complete code has been given above. If you want to get all the compressed packages of files:

Extraction code: slan

Please run the following code on the command line first:

selfGrootDefault(4)

Then run the demo in the compressed package
