Matlab aspect ratio. pbaspect (ratio) sets the plot box aspect ratio for the current axes. The plot box aspect ratio is the relative length of the x -axis, y -axis, and z -axis. Specify ratio as a three-element vector of positive values that represent the ratio of the x -axis, y -axis, and z -axis lengths. For example, [3 1 1] specifies that the length of the x ...

axis vis3d freezes aspect ratio properties to enable rotation of 3-D objects and overrides stretch-to-fill. axis normal automatically adjusts the aspect ratio of the axes and the relative scaling of the data units so that the plot fits the figures shape as best as possible. axis off turns off all axis lines, tick marks, and labels.

Aspect ratio remains constant during interaction, specified as a numeric or logical 0 (false) or 1 (true). When the value is true, the aspect ratio remains constant when you draw or resize the ROI. When the value is false, you can change the aspect ratio when drawing or resizing the ROI. You can change the state of this property using the ...pbaspect (ratio) sets the plot box aspect ratio for the current axes.

AR is the ratio of the number of columns to the number of rows, which is the aspect ratio. Sign in to comment.I don't believe there is an easy way to do it. There are two options: First, use the position part of the subplot: >> subplot (2,5, i, [l, b, w, h]) and calculate the left, bottom, width, height. Or, get the handle of the returned axis: >> h (i) = subplot (2,5,i); and then modify the axis afterward. >> set (h (1), 'position', [l, b, w, h] );Matlab will not provide axes of the same width and height.
