For example, to set the linestyle of a line to be dashed, you can do:: >>> line, = plot([1,2,3]) >>> setp(line, linestyle='--') If you want to know the valid types of arguments, you can provide the name of the property you want to set without a value:: >>> setp(line, 'linestyle') linestyle: [ '-' | '--' | '-.' | ':' | 'steps' | 'None' ] If you want to see all the properties that can be set, and their possible values, you can do:: >>> setp(line) ... long output listing omitted You may specify another output file to `setp` if `sys.stdout` is not acceptable for some reason using the `file` keyword-only argument:: >>> with fopen('output.log') as f: >>> setp(line, file=f) :func:`setp` operates on a single instance or a iterable of instances. If you are in query mode introspecting the possible values, only the first instance in the sequence is used. When actually setting values, all the instances will be set. e.g., suppose you have a list of two lines, the following will make both lines thicker and red:: >>> x = arange(0,1.0,0.01) >>> y1 = sin(2*pi*x) >>> y2 = sin(4*pi*x) >>> lines = plot(x, y1, x, y2) >>> setp(lines, linewidth=2, color='r') :func:`setp` works with the MATLAB style string/value pairs or with python kwargs. For example, the following are equivalent:: >>> setp(lines, 'linewidth', 2, 'color', 'r') # MATLAB style >>> setp(lines, linewidth=2, color='r') # python style Nrfiler)rr'z(The set args must be string, value pairscss|]\}}||fVqdS)Nr)rrrrrrrszsetp..rcsg|]}|qSr)r)rr)funcvalsrrrszsetp..csg|]}|jfqSr)r)rr)rrrrs)rjr"rrZflattenrpoprrprrrWrr )r+rrZobjsr,Z printArgsrr)r/rrsetps&2   ,$r1cCs>tjd}|r$dt|jddSdt|jddSdS)a Inspect an `~matplotlib.artist.Artist` class and return information about its settable properties and their current values.
