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. |
---|
27 | % |
