Matlab paper illustration drawing template issue 40 - pie chart with offset sector

In the previous post , Shared Matlab Drawing template of pie chart ：

further , Share again Pie chart with offset sector Drawing template for .

Let's take a look first Finished product effect ：

hot tip ：Matlab Thesis illustration drawing template series , It aims to reduce the use of Matlab The threshold for scientific research mapping , Just add the corresponding content according to the template format , You can get data illustrations that meet the format requirements of most journals and dissertations . If you feel useful, you can share it with your friends .

The most critical part of the template ：

 

1. Data preparation

This part is mainly about reading data , Define variables .

%  Reading data 
X = [0.49 0.12 0.1 0.08 0.08 0.04 0.04 0.05];
explode = [0 0 1 0 1 0 0 0];
Label = {'Brazil','Colombia','Argentina','Peru','Venezuela','Chile','Ecuador','Others'};

among , By putting the corresponding  explode  The element is set to 1 To offset No 3 And the 5 Pie slice .

 

2. Color definition

Color matching tests personal aesthetics , Need to try more .

here Directly use the previously shared addcolorplus Gradient in tool ：

%  gradient 
map = addcolorplus(282);
idx = linspace(1,64,8);
idx = round(idx);
C = map(idx,:);
C = flipud(C);

​3. Pie chart drawing with offset sectors

Use ‘pie’ command , draw Unrefined pie chart with offset sectors .

pie(X,explode)
hTitle = title('South American Population by Country');

 

4. Detail optimization

For the beauty of illustrations , utilize ’colormap’ Command to assign the color selected before ：

%  coloration 
colormap(C)

further , Adjust label 、 Font size 、 Background color, etc ：

%  label 
hLegend = legend(Label, 'Position', [0.85 0.15 0.1 0.3]);
hLegend.ItemTokenSize = [5 5];
legend('boxoff');
%  Font size 
th = findobj(gca, 'Type', 'text');
set(th, 'FontName', 'Arial', 'FontSize', 11)
set(hLegend, 'FontName',  'Arial', 'FontSize', 9)
set(hTitle, 'FontSize', 12, 'FontWeight' , 'bold')
%  The background color 
set(gcf,'Color',[1 1 1])

After setting up , With the resolution required by the journal 、 Format output picture .

%%  Image output 
print('test.png','-r300','-dpng');

You can also try other colors ：
