Details and Options

  • Possible forms of datei include:
  • DateObject[],TimeObject[]date or time object
    "string"DateString specification
    {y,m,d,h,m,s}DateList specification
    {y},{y,m},{y,m,d},shortened date list
    tabsolute time given as a single number
  • In shortened date lists, omitted elements are taken to have default values {y,1,1,0,0,0}.
  • Possible forms of datespec include:
  • {start,end}dates from start to end in equal increments
    {start,Automatic,Δt}dates beginning with start in increments Δt
    {Automatic,end,Δt}dates ending with end in increments Δt
    startdates with increments determined by the form of start
  • The Δt in datespec can be a {y,m,d,h,m,s} date list specification or any of the special forms "Year", "Quarter", "Month", "Week", "Day", "Hour", "Minute", "Second", and "Millisecond".
  • If no explicit Δt is given, the increments used will be the smallest time unit specified explicitly in start.
  • Data values vi can be given in the following forms:
  • via real-valued number
    Quantity[vi,unit]a quantity with a unit
    Around[vi,ei]value vi with uncertainty ei
    Interval[{vmin,vmax}]values between vmin and vmax
  • Values vi that are not of the preceding form are taken to be missing and are not shown.
  • The datai have the following forms and interpretations:
  • <|"k1"v1,"k2"v2,|>values {v1,v2,}
    <|date1v1,date2v2,|>key-value pairs {{date1,v1},{date2,v2},}
    SparseArrayvalues as a normal array
    TimeSeries, EventSeriestime-value pairs
    QuantityArraymagnitudes
    WeightedDataunweighted values
  • The following wrappers w can be used for the datai:
  • Annotation[datai,label]provide an annotation for the data
    Button[datai,action]define an action to execute when the points are clicked

  • Wrappers w can be applied at multiple levels:
  • {,w[vi],}wrap the value vi in a list
    {,w[{datei,vi}],}wrap the point {datei,vi}
    w[datai]wrap the data datai
    w[{data1,}]wrap a collection of data

  • DataRange determines how values {v1,,vn} are interpreted into {{date1,y1},,{xn,yn}}. Possible settings include:
  • Automatic,Alluniform from 1 to n
    {xmin,xmax}uniform from xmin to xmax
  • In general, a list of pairs {{x1,y1},{x2,y2},} is interpreted as a list of points, but the setting DataRangeAll forces it to be interpreted as multiple data {{y11,y12},{y21,y23},}.
  • Possible settings for PlotLayout that show multiple curves in a single plot panel include:
  • "Overlaid"show all the data overlapping
    "Stacked"accumulate the data
    "Percentile"accumulate and normalize the data
  • Possible settings for PlotLayout that show single curves in multiple plot panels include:
  • "Column"use separate curves in a column of panels
    "Row"use separate curves in a row of panels
    {"Column",k},{"Row",k}use k columns or rows
    {"Column",UpTo[k]},{"Row",UpTo[k]}use at most k columns or rows
  • Typical settings for PlotLegends include:
  • Noneno legend
    Automaticautomatically determine legend
    {lbl1,lbl2,}use lbl1, lbl2, as legend labels
    Placed[lspec,]specify placement for legend
  • All explicit coordinates in Prolog, Epilog, Ticks, etc. are taken to be dates.
  • Possible settings for ScalingFunctions include:
  • syscale y axis
    {sx,sy}scale x and y axes
  • Common built-in scaling functions s include:
  • "Reverse"reverse the coordinate direction
    "Infinite"infinite scale
  • Scales for the y axis are applied after the default log scale has been applied.
