如何繪制Matlab中所示的網格圖形？

Question

我將在上面的圖上繪制一些方框，其中有些字符或沒有字符。 謝謝。

Answer 1

如果您確實想要繪圖，可以使用以下函數進行處理：

function plotGrid(x)

dims = size(x);

% Get grid
tick_x = linspace(0, 1, dims(2)+1);
tick_y = linspace(0, 1, dims(1)+1);

% Get center points
pt_x = (0.5:dims(2)) / dims(2);
pt_y = (0.5:dims(1)) / dims(1);

[pt_x pt_y] = meshgrid(pt_x, pt_y);

% Plot
figure; hold on; axis off
plot([tick_x; tick_x], repmat((0:1)', 1, dims(2)+1), 'k')
plot(repmat((0:1)', 1, dims(1)+1), [tick_y; tick_y], 'k')
text(pt_x(:), pt_y(:), x(:), 'HorizontalAlignment', 'center')

例如：

>> x = num2cell(randi(10, [10 6]));
>> plotGrid(x)

Answer 2

在圖形上顯示表格數據的一種方法是使用UITABLE ：

data = 

    'U1'    'U2'    'U3'    'U4'    'U5' 
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []       []
      []      []      []      []    'U85'

>> uitable('Data', data, 'Units', 'normalized', 'Position', [0 0 1 1]);
