Chart

Draws a chart. Its appearance and data are set with UI Attributes. More than one set of values can be specified.

Parameters

• id: the object's ID, used by UISets. Required
• position: the object's position. Use the pixels or rows and columns coordinates format
• size: the chart's area's width and height
• attributes: list of UI attribute ids and values defining the chart's aspect and data. Setting this parameter is the same as setting each UI attribute with a UISet

Syntax

(chart!<id> <address>; <position>; <width>; <height>; <attributes>)

E.g.

(chart!chart1 x3y187; 312; 180; (type=line; values=0,10,24,12,7,35,42,1,23,4))

	spline	Draws a spline connecting the values
orientation	vertical	Default value. Draws a vertical chart
	horizontal	Draws an horizontal chart
value	single value	Value to be drawn. To be used when "type" is gauge

values	comma-separated list of values	Values to be drawn. E.g. 2,3,1.2,4
	comma-separated list of arrays	Sets of values to be drawn. E.g. [2,3,1.2,4],[4,1,0,0.2]
values[n]		Same as "values", but applies to a specific set of values
valuerange	[min],[max]	Range of values displayed. E.g. -2,10
axislabels	auto	Default. Labels on the x axis (if vertical) or y axis (if horizontal) will go from 1 to the total number of values.
	none	No label is shown on the x axis (if vertical) or y axis (if horizontal)
	comma-separated list of values	Custom labels on the x axis (if vertical) or y axis (if horizontal)
valuelabeltype	inside	Value labels are shown inside (if "type" is bars, points or gauge) or over (if "type" is line or spline)
	outside	Value labels are shown above or below
	popup	Value labels are shown on mouseover, or on touch (if on a touch-enabled device)
valuelabelcolor	CSS color	Color of the value labels font
valuelabels	comma-separated list of values	Custom values to show in value labels
valuelabels[n]		Same as "valuelabels", but applies to a specific set of values
spacing	0-100	Percentage of spacing between bars or points
spacing[n]		Same as "spacing", but applies to a specific set of values
offset[n]	percentage	Percentage of value offset. Used to shift a specific set on the x axis if vertical, or on the y axis if horizontal. Used to show background sets. E.g. "offset[0]=-20; offset[1]=20"
drawaxis	true	Default. The axes are visible (also notches and labels)
	false	The axes are not visible (also notches and labels)
axisoffset	percentage	The axis offset (y if vertical, x if horizontal) expressed as percentage or as the value series index. E.g. "50%" or "3"
origin	value	moves the origin to a value different from 0 ( e.g. origin=3.2 )
notches	value	number of notches on the x-axis (for vertical charts) or on the y-axis (for horizontal charts)

valuecolor	CSS color	a color that applies to all values
valuecolor[n]	CSS color	a color that applies to all values in the specified value set
valuecolors	comma-separated list of CSS colors	list of colors, one for each data point in values
