v scaled to 0..m, rounded (all 0 when v is all 0).

labels b_ars values: a horizontal bar per value, labeled, the longest 40 wide, each followed by its value (values >= 0).

s_park v: v as a sparkline, one block character per value, its height from the least (lowest) to the greatest (highest).

n h_istogram v: v counted into n bins of equal width from its least to its greatest, drawn as bars labeled by each bin's range.

(w c_at h) s_catter xy: the points xy (2 rows, x over y, as []P_ATH takes them) marked * on a character grid w wide and h high, y up.

l_ine! v: v as a line chart with axes, a picture shown with []S_HOW; gives the picture's SVG text. The vertical axis spans the values (however small their range), the horizontal one the positions 1 to t_ally v; a single value is drawn as a point.

names l_ines! series: several lines in one chart, one per boxed vector of series (each its own length), colored in turn and named in a legend by names (a boxed text per series).

labels c_hart! series: as l_ines!, with a title and the names of the axes: labels is the title, the horizontal axis's name, the vertical axis's name, then a name per series ("" for none).

n l_inspace (lo, hi): n evenly spaced Floats from lo to hi inclusive (n = 1 gives lo). Sample a function over it with e_ach or m_ap: ys := 'f e_ach (n l_inspace (lo, hi)).

xy f_unction!: xy (2 rows, x over y, as []P_ATH and s_catter take them) as a line chart with a real-valued horizontal axis, a picture shown with []S_HOW; gives the picture's SVG text. The vertical axis spans y's values; the horizontal one spans x's.

names f_unctions! series: several curves in one chart, one per boxed (x over y) pair of series (each its own length and its own x values), colored in turn and named in a legend by names.

labels f_unctionChart! series: as f_unctions!, with a title and the names of the axes (as c_hart!'s labels).

The horizontal range of one (x over y) pair, padded as the vertical axis is.

The horizontal range across every boxed (x over y) pair of series, so curves of different x values still share one axis.

The chart's frame: the picture's size and the plot area's edges.

The line colors, in turn (blue, red, green, amber, violet, teal).

Boxed numbers joined into one vector.

labels c_hart series: the picture's SVG text.

How far past its least and greatest values the vertical axis goes: 0, or for a flat series a tenth of its size (1 when it is 0).

Boxed texts joined into one text (none is the empty text).

The color of series i (1, 2, ...), the colors in turn.

The x of positions p (0, 1, ...) of n: spread across the plot area, one position in its middle.

x rounded to a whole number, still a Float.

The y of values v in the vertical range box (least, greatest).

The x of values v in the horizontal range box (least, greatest): h:y_at's mapping, left to right instead of inverted.

One (x over y) series as a polyline (and a point when it has one value), in its color: color s_eriesXY (xbox; ybox; xy), boxed.

One series as a polyline (and a point when it has one value), in its color: color s_eries (n; box; values), boxed (n a Float).

The text attributes of tick labels and names.

The axes, the grid lines and the tick labels: three values on the vertical axis (least, middle, greatest), the first and last positions on the horizontal one.

The axes, the grid lines and the tick labels, both real-valued: three ticks on each axis (least, middle, greatest), as h:f_rame's vertical axis already reads, but the horizontal one too.

labels c_hartXY (xbox, series): as h:c_hart, but series is a boxed (x over y) pair per curve and the horizontal axis spans xbox (its own real values, not a count) instead of a position.

The title, the axes' names and the legend from labels (title, horizontal axis, vertical axis, then a name per series); empty ones are left out.

An element, or nothing when the text it shows is empty.
