Plots Visual Average ratng: 3,8/5 5706 reviews

Plot y versus x as lines and/or markers.

Call signatures:

  • Stem and leaf plots are data dense visualizations that organize large amounts of micro-level numeric data to form larger macro-level visual distributions. These plots can be extended with font.
  • Created by Tom Breloff (@tbreloff) Maintained by the JuliaPlots members. Plots is a plotting API and toolset. My goals with the package are: Powerful. Do more with less. Complex visualizations become easy. Stop reading so much documentation. Commands should 'just work'. Less code means fewer mistakes and more.
  • Correlation plots can be used to quickly find insights. It is used to investigate the dependence between multiple variables at the same time and to highlight the most correlated variables in a data table. In this visual, correlation coefficients are colored according to the value.

Try these plot ideas to get your brain a’storming. Some are realistic. Others are just ludicrous. Some have been done before. The point is for you to tell the story differently. Ask yourself why when reading these. A world wherein employees work nonstop with no vacation—a riot ensues.

The coordinates of the points or line nodes are given by x, y.

The optional parameter fmt is a convenient way for defining basicformatting like color, marker and linestyle. It's a shortcut stringnotation described in the Notes section below.

You can use Line2D properties as keyword arguments for morecontrol on the appearance. Line properties and fmt can be mixed.The following two calls yield identical results:

When conflicting with fmt, keyword arguments take precedence.

Plotting labelled data

There's a convenient way for plotting objects with labelled data (i.e.data that can be accessed by index obj['y']). Instead of givingthe data in x and y, you can provide the object in the dataparameter and just give the labels for x and y:

All indexable objects are supported. This could e.g. be a dict, apandas.DataFame or a structured numpy array.

Plotting multiple sets of data

There are various ways to plot multiple sets of data.

  • The most straight forward way is just to call plot multiple times.Example:

  • Alternatively, if your data is already a 2d array, you can pass itdirectly to x, y. A separate data set will be drawn for everycolumn.

    Example: an array a where the first column represents the xvalues and the other columns are the y columns:

  • The third way is to specify multiple sets of [x], y, [fmt]groups:

    In this case, any additional keyword argument applies to alldatasets. Also this syntax cannot be combined with the dataparameter.

Plots visual basic

By default, each line is assigned a different style specified by a'style cycle'. The fmt and line property parameters are onlynecessary if you want explicit deviations from these defaults.Alternatively, you can also change the style cycle usingrcParams['axes.prop_cycle'] (default: cycler('color', ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf'])).

Parameters:
x, yarray-like or scalar

The horizontal / vertical coordinates of the data points.x values are optional and default to range(len(y)).

Commonly, these parameters are 1D arrays.

They can also be scalars, or two-dimensional (in that case, thecolumns represent separate data sets).

These arguments cannot be passed as keywords.

fmtstr, optional

A format string, e.g. 'ro' for red circles. See the Notessection for a full description of the format strings.

Format strings are just an abbreviation for quickly settingbasic line properties. All of these and more can also becontrolled by keyword arguments.

This argument cannot be passed as keyword.

dataindexable object, optional

An object with labelled data. If given, provide the label names toplot in x and y.

Note

Technically there's a slight ambiguity in calls where thesecond label is a valid fmt. plot('n','o',data=obj)could be plt(x,y) or plt(y,fmt). In such cases,the former interpretation is chosen, but a warning is issued.You may suppress the warning by adding an empty format stringplot('n','o',',data=obj).

Returns:
lines

A list of Line2D objects representing the plotted data.

Other Parameters:
scalex, scaleybool, optional, default: True

These parameters determined if the view limits are adapted tothe data limits. The values are passed on to autoscale_view.

**kwargsLine2D properties, optional

kwargs are used to specify properties like a line label (forauto legends), linewidth, antialiasing, marker face color.Example:

If you make multiple lines with one plot command, the kwargsapply to all those lines.

Notes

Format Strings

A format string consists of a part for color, marker and line:

Each of them is optional. If not provided, the value from the stylecycle is used. Exception: If line is given, but no marker,the data will be a line without markers.

Other combinations such as [color][marker][line] are alsosupported, but note that their parsing may be ambiguous.

Markers

If the color is the only part of the format string, you canadditionally use any matplotlib.colors spec, e.g. full names('green') or hex strings ('#008000').
