在matlab中創建堆積條形圖

Question

嗨我正在嘗試在matlab中創建堆積條形圖，但輸出圖似乎將第一個數據集（AD_monthly_generation_250）添加到第二個（CC_monthly_demand_2012）。我怎樣才能避免這種情況？

我的代碼是

%% AD STACKED CC %% 

AD_monthly_generation_250 = [186 186 186 186 186 186 186 186 186 186 186 186]'; 
CC_monthly_demand_2012 = [199.575 206.701 145.284 135.944 127.689 93.281 80.311 78.859 98.145 168.572 206.365 113.030]'; 


% Create a stacked bar chart using the bar function 
figure; 
bar(1:12, [ AD_monthly_generation_250 CC_monthly_demand_2012 ], 0.5, 'stack'); 


% Add title and axis labels 
title('Seasonal Anaerobic Digestion (250kWe) Supply to Demand - 2012','FontSize',22); 
set(gca,'XTickLabel',{'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug',' Sep',  'Oct', 'Nov',' Dec'},'FontSize',18) 
ylabel('Energy (MWh)'); 

Answer 1

我認爲'stack'選項工作方式應該嘗試這種代碼，也許這是你想要的東西：

%% AD STACKED CC %% 

AD_monthly_generation_250 = [186 186 186 186 186 186 186 186 186 186 186 186]'; 
CC_monthly_demand_2012 = [199.575 206.701 145.284 135.944 127.689 93.281 80.311 78.859 98.145 168.572 206.365 113.030]'; 

% Create a stacked bar chart using the bar function 
figure; 
% bar(1:12, [ AD_monthly_generation_250 CC_monthly_demand_2012 ], 0.5, 'stack'); 
bar(1:12, AD_monthly_generation_250, 0.5, 'b'); 
hold on; 
bar(1:12, CC_monthly_demand_2012, 0.5, 'r'); 
hold off; 

% Add title and axis labels 
title('Seasonal Anaerobic Digestion (250kWe) Supply to Demand - 2012','FontSize',22); 
set(gca,'XTickLabel',{'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug',' Sep',  'Oct', 'Nov',' Dec'},'FontSize',18) 
ylabel('Energy (MWh)');
