Statistics & data-viz

20 functions in 11 classes, grouped by what they do, each with the explanation the library gives of itself.

The story of this area, for a general reader: what a crafter does with it, an example run and its rated lanes, is on its Platform page.

The functions, by what they do

Counting and measuring

NumberOfCachedValues simple cache system in stzDataSet
composed example
```
o1 = new stzDataSet([ 2, 4, 4, 5, 7, 9, 12, 25 ])
? o1.NumberOfCachedValues()
#--> 0
```
composed from the signature, run for this page
Mean Statistical methods for histogram in stzHistogram
composed example
```
o1 = new stzHistogram([ 1, 2, 2, 3, 3, 3, 4, 4, 5 ])
? o1.Mean()
#--> 3
```
composed from the signature, run for this page

Replacing and setting

SetHAxis Horizontal axis methods (with Y aliases for compatibility) in stzHistogram
SetVAxis Vertical axis methods (with X aliases for compatibility) in stzHistogram
SetXAxis X-axis aliases for backward compatibility in stzHistogram
SetYAxis Y-axis aliases for backward compatibility in stzHistogram
SetBinCount Configuration methods in stzHistogram
SetXYAxis X/Y aliases in stzScatterPlot
SetBarChar Character customization with H/V naming in stzBarPlot

Removing

RemoveDuplicates PILLAR 1: DATA CLEANING ====================== in stzDataWrangler

composed example

o1 = new stzDataWrangler([ [ "  John ", "25", "sales" ], [ "John", "25", "sales" ], [ "mary", "", "mkt" ] ], [ "Name", "Age", "Dept" ])
? o1.RemoveDuplicates()
#--> 0

composed from the signature, run for this page

ClearCache simple cache system in stzDataSet

Adding

AddRule rule management methods in stzDataSet
AddInsightRule rule management methods in stzDataSet
AddWeightedRule rule management methods in stzDataSet

Converting

ToString The binning and the drawing both live in plot.zig now, so a Python or C face over the engine gets a histogram, not a pile of edges it must draw itself. What stays here is what a face is for: read the configuration, cross once, hand back the text. in stzHistogram
ToCanvasQ ROUND FIRST, THEN COMPACT. Rounding kills the float artefact that makes an edge print as 3.40000000004, and compacting keeps a large edge short (2.7K). -- the PIXEL tiers (GR6c) -------------------------------------------- The SAME bins the terminal draws -- counts and labels come from the binning, so the two pictures cannot disagree about the distribution. Bars touch, because the bins do. in stzHistogram
ToStringInRing THE HARO RENDERER THIS WAS PORTED FROM, verbatim, so the guard can prove the two agree character for character. in stzHistogram
ConvertDataTypes PILLAR 3: DATA TRANSFORMATION ============================= in stzDataWrangler

Showing, drawing and formatting

PlotKind Options ride through to stzPlotCanvas: :Width :Height :Title :Font :Color :Background :Grid :ShowValues :ShowAverage :Min :Max in stzBarPlot

Reading and writing

ExportForStzDataSet PILLAR 5: EXPORT AND INTEGRATION ================================ in stzDataWrangler
