DateListLogPlot

DateListLogPlot[{{date1,v1},{date2,v2},…}]
makes a log plot with values vi at a sequence of dates.
DateListLogPlot[{v1,v2,…},datespec]
makes a log plot with dates at equal intervals specified by datespec.
DateListLogPlot[tseries]
plots the time series tseries.
DateListLogPlot[{data1,data2,…}]
plots data from all the datai.
DateListLogPlot[{…,w[datai],…}]
plots datai with features defined by the symbolic wrapper w.
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 t absolute 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 start dates 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:
-
vi a 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},…} SparseArray values as a normal array TimeSeries, EventSeries time-value pairs QuantityArray magnitudes WeightedData unweighted 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 EventHandler[datai,…] define a general event handler for the points Hyperlink[datai,uri] make the points a hyperlink Labeled[datai,label] label the data Legended[datai,label] identify the data in a legend PopupWindow[datai,cont] attach a popup window to the points StatusArea[datai,label] display in the status area on mouseover Style[datai,styles] show the points using the specified styles Tooltip[datai,label] attach a tooltip to the points Tooltip[datai] use data values as tooltips for the points - 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 w1[w2[…]] use nested wrappers - In DateListLogPlot, Labeled and Placed allow the following positions:
-
Automatic automatically placed labels Above, Below, Before, After positions around the data date near the data at date Scaled[s] scaled position s along the data {s,Above},{s,Below},… relative position at position s along the data {pos,epos} epos in label placed at relative position pos of the data - DateListLogPlot has the same options as Graphics, with the following additions and changes:
-
AspectRatio 1/GoldenRatio ratio of height to width Axes Automatic whether to draw axes ClippingStyle None what to draw when lines are clipped ColorFunction Automatic how to determine the coloring of lines ColorFunctionScaling True whether to scale arguments to ColorFunction DataRange Automatic the range of x values to assume for data DateFunction Automatic how to convert dates to standard form DateTicksFormat Automatic format for date tick labels Filling None how to fill in stems for each point FillingStyle Automatic style to use for filling Frame True whether to put a frame around the plot InterpolationOrder None the polynomial degree of curves used in joining data points IntervalMarkers Automatic how to render uncertainty IntervalMarkersStyle Automatic style for uncertainty elements Joined False whether to join points LabelingSize Automatic maximum size of callouts and labels MaxPlotPoints Infinity the maximum number of points to include Mesh None how many mesh points to draw on each line MeshFunctions {#1&} how to determine the placement of mesh points MeshShading None how to shade regions between mesh points MeshStyle Automatic the style for mesh points Method Automatic methods to use PerformanceGoal $PerformanceGoal aspects of performance to try to optimize PlotLabel None overall label for the plot PlotLabels None labels for data PlotLayout "Overlaid" how to position data PlotLegends None legends for datasets PlotMarkers None markers to use to indicate each point PlotRange Automatic range of values to include PlotRangeClipping True whether to clip at the plot range PlotStyle Automatic graphics directives to determine styles of points PlotTheme $PlotTheme overall theme for the plot TargetUnits Automatic units to display in the plot - DataRange determines how values {v1,…,vn} are interpreted into {{date1,y1},…,{xn,yn}}. Possible settings include:
-
Automatic,All uniform 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:
-
None no legend Automatic automatically 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:
-
sy scale 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.
