value less than 1 reduces the size of the label. The optional parameter Names.arg allows you to specify a character vector as the label name for the bar. You can also use graphical parameters to assist in adjusting text intervals.6.1.5 Spine-like chartBefore we end the discussion of bar charts, let's look at a special bar chart called a Spine chart (Spinogram). The spikes are re-scaled for stacked bar charts so that each bar has a height of 1 and the height of each segment is expressed as a sca
the graph is extended in any direction to the layout.
The layout of the tree
Tree layout algorithm is relatively simple, only need to follow some basic principles on it:
1. A certain distance should be maintained between nodes in the same layer.
2. The parent node needs to be in the central location of all child nodes it contains
3. The whole tree should be kept as symmetrical and balanced as possible.
4. The same subtree should have the same r
