[37] | 1 | function H = tightsubplot(varargin) |
---|
| 2 | % TIGHTSUBPLOT Tiles axes without wasting space |
---|
| 3 | % H = TIGHTSUBPLOT(K,P) returns an handle to the P-th axis in a |
---|
| 4 | % regular grid of K axes. The K axes are numbered from left to right |
---|
| 5 | % and from top to bottom. The function operates similarly to |
---|
| 6 | % SUBPLOT(), but by default it does not put any margin between axes. |
---|
| 7 | % |
---|
| 8 | % H = TIGHTSUBPLOT(M,N,P) retursn an handle to the P-th axes in a |
---|
| 9 | % regular subdivision with M rows and N columns. |
---|
| 10 | % |
---|
| 11 | % The function accepts the following option-value pairs: |
---|
| 12 | % |
---|
| 13 | % 'Spacing' [0] |
---|
| 14 | % Set extra spacing between axes. The space is added between the |
---|
| 15 | % inner or outer boxes, depending on the setting below. |
---|
| 16 | % |
---|
| 17 | % 'Box' ['inner'] (** ONLY >R14 **) |
---|
| 18 | % If set to 'outer', the function displaces the axes by their |
---|
| 19 | % outer box, thus protecting title and labels. Unfortunately |
---|
| 20 | % MATLAB typically picks unnecessarily large insets, so that a bit |
---|
| 21 | % of space is wasted in this case. If set to 'inner', the |
---|
| 22 | % function uses the inner box. This causes the instets of nearby |
---|
| 23 | % axes to overlap, but it is very space conservative. |
---|
| 24 | % |
---|
| 25 | % REMARK. While SUBPLOT kills any pre-existing axes that overalps a |
---|
| 26 | % new one, this function does not. |
---|
