matplotlib.pyplot.setp — Matplotlib 3.10.3 documentation (original) (raw)
matplotlib.pyplot.setp(obj, *args, **kwargs)[source]#
Set one or more properties on an Artist, or list allowed values.
Parameters:
The artist(s) whose properties are being set or queried. When setting properties, all artists are affected; when querying the allowed values, only the first instance in the sequence is queried.
For example, two lines can be made thicker and red with a single call:
x = arange(0, 1, 0.01) lines = plot(x, sin(2pix), x, sin(4pix)) setp(lines, linewidth=2, color='r')
filefile-like, default: sys.stdout
Where setp writes its output when asked to list allowed values.
with open('output.log') as file: ... setp(line, file=file)
The default, None, means sys.stdout.
*args, **kwargs
The properties to set. The following combinations are supported:
- Set the linestyle of a line to be dashed:
line, = plot([1, 2, 3])
setp(line, linestyle='--') - Set multiple properties at once:
setp(line, linewidth=2, color='r')
- List allowed values for a line's linestyle:
setp(line, 'linestyle')
linestyle: {'-', '--', '-.', ':', '', (offset, on-off-seq), ...} - List all properties that can be set, and their allowed values:
setp(line)
agg_filter: a filter function, ...
[long output listing omitted]
setp also supports MATLAB style string/value pairs. For example, the following are equivalent:
setp(lines, 'linewidth', 2, 'color', 'r') # MATLAB style setp(lines, linewidth=2, color='r') # Python style
