Preserve Axis Limits and Tick Values. Occasionally, the exportgraphics function saves your content with different axis limits or tick values depending on the size of the font and the resolution of the file. To keep the axis limits and tick values from changing, set the tick value mode and limit mode properties on the axes to 'manual'.Set the axes box aspect. that face. This is not to be confused with the data aspect. (which for Axes3D is always 'auto'). The default ratios are. 4:4:3 (x:y:z). aspect to match your data range in each dimension. *zoom* controls the overall size of the Axes3D in the figure. of the axis lengths in display units is x:y:z.When the data aspect ratio mode is auto, MATLAB adjusts the data aspect ratio so that each axis spans the space available in the figure window. If you are displaying a representation of a real-life object, you should set the data aspect ratio to [1 1 1] to produce the correct proportions.

Current data aspect ratio mode, returned as either 'auto' or 'manual'. When the mode is automatic, MATLAB ® determines the appropriate data aspect ratio value. If you specify a value, then the mode changes to manual. Querying the data aspect ratio mode returns the DataAspectRatioMode property value for the corresponding Axes object. For the aspect ratio: you should gather all your illustration graph and plots and find the best way to present it preserving the text size in XY axes and legends. and try to classify all of those illustrations into categories depending on their layout ratio 1:1 1:1.5 1:2 1:3 and vice versa. And.
