如何使网格线与刻度线颜色相同

更改记号的步骤

请参见 NumericRuler properties . 简而言之:

ax = gca;
ax.XAxis.Color = [.8,.8,.8]; % grey as RGB triplet
ax.YAxis.Color = 'blue';     % blue as option keyword

更改网格线的步骤

你是对的 ax.GridColor ,但默认情况下,您有一个半透明栅格,因此还需要设置 ax.GridAlpha .

ax = gca;
ax.GridColor = [0 0 0]; % Black as RGB, this is [0.15 0.15 0.15] by default (dark grey)
ax.GridAlpha = 1;       % Opaque, this is 0.15 by default (85% transparent) 

让他们一样

ax = gca;
% Set the grid to be opaque
ax.GridAlpha = 1;
% Set them to be the same colour
myColour = [0.4, 0.7, 1]; % Any RGB triplet etc.
ax.GridColor = myColour;
ax.XAxis.Color = myColour;
ax.YAxis.Color = myColour;
