Matlab paper illustration drawing template No. 42 - bubble matrix diagram (correlation coefficient matrix diagram)

在上一篇文章中,分享了Matlab气泡图的绘制模板：

进一步,Suppose we want to visualize a table or matrix,That is, the bubbles are arranged in a matrix,And the size and color of each bubble represent the value of its corresponding feature,应该怎么操作呢？

Take a look at the finished product：

特别提示：Matlab论文插图绘制模板系列,旨在降低大家使用Matlab进行科研绘图的门槛,只需按照模板格式添加相应内容,即可得到满足大部分期刊以及学位论文格式要求的数据插图.如果觉得有用可以分享给你的朋友.

模板中最关键的部分内容：

1. 数据准备

此部分主要是读取数据,Generate matrix coordinate data.

% 读取数据load data.mat% Generate matrix coordinate data[r,c] = size(data);x = 1:c;y = 1:r;[xx,yy] = meshgrid(x,y);yy = flipud(yy);

其中,利用‘meshgrid’command to generate coordinate data for a matrix.

值得注意的是,在竖直方向,The index numbering order of the matrix is ​​opposite to the positive direction of the coordinate axis,所以使用‘flipud’command to flip the matrix upside down.

2. 颜色定义

由于It needs to be colored according to the size of the feature,So use a gradient color scheme.

这里直接用之前分享的addcolorplus工具的渐变色：

%% 颜色定义map = addcolorplus(300);

3. Bubble matrix graph drawing

使用‘bubblechart’命令,绘制Unprettified bubble matrix diagram.

bubblechart(xx(:),yy(:),data(:)*10,data(:),'MarkerFaceAlpha',1);hTitle = title('BubbleMatrix Plot');hXLabel = xlabel('XAxis');hYLabel = ylabel('YAxis');

其中, data(:)*10Used to define the bubble size,data(:)Used to define the bubble color,This is just to illustrate the two dimensions of features that can be represented by color and size.

4. 细节优化

为了插图的美观,使用colormap命令赋上之前选择好的颜色.

% 赋色colormap(map)

然后,使用‘bubblesize’The command defines the size of the smallest and largest bubbles：

% Adjust bubble sizebubblesize([10 30])

进一步,Make adjustments to the axes：

% 坐标轴美化axis equalset(gca, 'Box', 'on', ...                                     'XGrid', 'on', 'YGrid', 'on', ...                           'TickDir', 'in', 'TickLength', [0 0], ...                  'XMinorTick', 'off', 'YMinorTick', 'off', ...                   'XColor', [.1 .1 .1],  'YColor', [.1 .1 .1],...                 'XTick', 0:1:c+1,...

'Location','northeastoutside',...    'NumBubbles',3,... ...    'FontName', 'Helvetica',...    'FontSize', 10);colorbar('Position',[0.79,0.11,0.03,0.5])% 字体字号set(gca, 'FontName', 'Arial', 'FontSize', 10)set([hXLabel,hYLabel], 'FontName',  'Arial', 'FontSize', 11)set(hTitle, 'FontSize', 13, 'FontWeight' , 'bold')% 背景颜色set(gcf,'Color',[1 1 1])

最后,按照所需分辨率、格式输出图片.

figW = figureWidth;figH = figureHeight;set(figureHandle,'PaperUnits',figureUnits);set(figureHandle,'PaperPosition',[0 0 figW figH]);fileout = 'test';print(figureHandle,[fileout,'.png'],'-r300','-dpng');

也可以尝试其它配色：

以上.
