axis([xmin xmax ymin ymax]): [ ]中分別給出x軸和y軸的最大值、最小值。（ sets scaling for the x- and y-axes on the current plot.）
axis([xmin xmax ymin ymax zmin zmax]):[ ]中分別給出x軸、y軸、z軸的最大值、最小值。（sets the scaling for the x-, y- and z-axes on the current 3-D plot）
axis equal 或axis(‘equal’) :表示x軸和y軸的單位長度相同。（sets the aspect ratio so that equal tick mark increments on the x-,y- and z-axis are equal in size）
axis square 或 axis(‘square’): 顯示的坐標系呈正方形。（makes the current axis box square in size.）
axis off 或 axis(‘off’) :關閉所有坐標軸線、刻度標記和標簽。（turns off all axis labeling, tick marks and background）
axis auto:基於x、y和z的最大值和最小值來自動設置坐標軸的范圍。用戶可以只限定某一個坐標軸，如：axis 'auto x'用來限定x軸的范圍;axis 'auto yz'用來限定y軸和z軸的范圍。（returns the axis scaling to its default, automatic mode where，for each dimension, 'nice' limits are chosen based on the extents of all line, surface, patch, and image children.）
axis manual:將坐標軸的范圍鎖定為當前范圍。如果打開了hold on命令，則后續的圖形都使用同樣的坐標范圍。該函數設置XLimMode、YLimMode和ZLimMode屬性為manual值。（freezes the scaling at the current limits, so that if HOLD is turned on, subsequent plots will use the same limits.）
axis tight:設置坐標軸的范圍為數據的范圍。（sets the axis limits to the range of the data.）
axis fill:設置坐標軸的范圍以及PlotBoxAspectRatio屬性。坐標軸將填充整個矩形局域。只有PlotBoxAspectRatioMode或DataAspectRatioMode屬性值為 manual時，該方法才起作用。（sets the axis limits and PlotBoxAspectRatio so that the axis fills the position rectangle.）
a
xis ij:將坐標系的原點設置到左上角。i軸為垂直軸，正方向為從上到下。j軸為水平軸，正方向為從左到右。(puts MATLAB into its "matrix" axes mode. The coordinate system origin is at the upper left corner. The i axis is vertical and is numbered from top to bottom. The j axis is horizontal and is numbered from left to right.)
axis xy:在默認的笛卡爾坐標系中繪制圖形，坐標系的原點在左下角。x軸為水平坐標軸，正方向為從左到右;y軸為垂直坐標軸，正方向為從下到上。(puts MATLAB into its default "Cartesian" axes mode. The coordinate system origin is at the lower left corner. The x axis is horizontal and is numbered from left to right. The y axis is vertical and is numbered from bottom to top.)
axis on:關閉所有坐標軸線、刻度標記和標簽。( turns axis labeling, tick marks and background back on)
axis image:功能與axis equal相同。只不過坐標軸的邊框緊貼在數據的四軸。多用來顯示圖片。(is the same as AXIS EQUAL except that the plot box fits tightly around the data.)
axis normal:自動調節坐標軸的縱橫比，從而是圖形隨窗口的形狀而改變.(restores the current axis box to full size and removes any restrictions on the scaling of the units.This undoes the effects of AXIS SQUARE and AXIS EQUAL)
v=axis:返回一個行向量，向量中的元素包含x、y和z軸的刻度因子。v具有四個或六個元素，這取決於當前坐標軸是二維的還是三維的。返回值是當前坐標軸的XLim、YLim和ZLim屬性的值。(returns a row vector containing the scaling for the current plot. If the current view is 2-D, V has four components; if it is 3-D, V has six components.)
axis Vis3D：鎖定坐標軸的縱橫比.(freezes aspect ratio properties to enable rotation of 3-D objects and overrides stretch-to-fill.)
