XYDT

Purpose:

Creates an XY plot from Date, Time and Y series.

XYDT(date, time, y, gap)

date	-	A series of date values.
time	-	A series of time values.
y	-	A series, the Y values.
gap	-	Optional. A real specifying the duration in days of a time gap to plot as a blank line. Defaults to 0.0 (no gaps).

An XY series.

W1: {julstr("1-1-99"), julstr("1-10-99"), julstr("4-2-99")};setvunits("daily")

W2: {todstr("12:00"), todstr("14:00"), todstr("9:35")};setvunits("time")

W3: {1, 2, .5};setvunits("V")

W4: xydt(w1, w2, w3)

The series in W4 consists of the values:

1-01-99 12:00, 1.0

1-10-99 14:00, 2.0

4-02-99 09:35, 0.5

W5: xydt(w1, w2, w3, 20)

Same as above except a gap appears between the 2nd and 3rd values.

To configure the x-axis to display both date and time values, use:

SETCONFIG("dt_scales_format", 1).

If gap > 0, nan values are inserted where the time between successive samples exceeds the gap. This results in a blank line separating time sections.
