pie(x): Draw a pie chart of data x. x can be a vector or a matrix. Each element in x will represent a sector of the pie chart, and the pie chart will show the proportion of the sum of the elements.
pie(x, explode): Draw a pie chart of data x, where the parameter explode can be used to set an important sector in the pie chart for extractive and focused display. It should be noted that the length of the explode vector is the same as that in x The number of elements is equal and corresponds to the meaning of the elements in x. The explode element has a non-zero value, and the corresponding element sectors will be displayed separately from the pie chart. Normally, the non-zero values are set to 1.
pie (x, labels): draw a pie chart data x, where labels can be used to set display parameters for each sector of the pie chart labels, labels should be noted that the parameter vector X using the data in the pie chart is depicted a string or number Example : For a graduate student, the average monthly expenses in a year are 190 yuan for living expenses, 33 yuan for materials, 45 yuan for telephone charges, 42 yuan for clothes purchase, and 45 yuan for other expenses. Please use a pie chart to show his monthly consumption ratio, and separate the slices with the most used expenses and the least used expenses in the pie chart. x=[190 33 45 42 45]; % separate display settings explode=[1 1 0 0 0]; % drawing figure() colormap hsv pie(x,explode,{'living expenses','data expenses','phone expenses ','Purchase clothes','Other expenses'}) title('Pie chart') % The random function generates a 5*3 array, and rounds the generated data Y = round(rand(5,3)*10); % Plotting subplot(2,2,1) bar(Y,'group') title'Group ' % Heap two-dimensional vertical bar graph subplot(2,2,2) bar(Y,'stack') title(' Stack') %Heap type two-dimensional horizontal bar graph subplot(2,2,3) barh(Y,'stack') title('Stack') % Set the width of the bar to 1.5 subplot(2,2,4) bar(Y,1.5) title('Width = 1.5') CSDN: Mathematical modeling summary of MATLAB drawing
