`CoordinateXType`, `CoordinateYType`	`Absolute`, `Relative`, `Pixel`, `Session`
`Width`, `Height`	size, for the shapes which have one
`XOffset`	shift on X
`Area`	chart area: `ChartAreaRef.Main` or the `ChartArea` of the indicator
`Visible`	drawn or not
`PlotForeground`	drawn over the bars
`IsExtended`	a line continues to the edge of the chart
`MaxBarsViewed`	not drawn when more than this number of bars are visible

Look

Member	Meaning
`LineColor`, `LineWidth`, `LineDashStyle`	border or line
`BackColor`, `BackGradient`	fill
`LineColor2`, `LineWidth2`, `LineDashStyle2`, `BackColor2`, `BackGradient2`	second line and fill, for the shapes which have two
`Margin`, `PixelMargin`, `MinPxForMargin`	space outside the shape, in pixels
`Padding`, `PixelPadding`	space inside the shape, in pixels

Text

Member	Meaning
`Text`, `ForeColor`, `FontSize`, `FontBold`	the text
`TextAlign`, `LabelAlign`	alignment
`Tooltip`	text shown when the mouse is over the annotation
`ShowLabel`, `ShowLblBackground`, `ShowPrice`	label and price of a level

Levels and children

Member	Meaning
`AddAnnParam(coeff, color, lineWidth, style)`, `ClearAnnParam()`	levels of a retracement or projection
`Ann1ToPlot`, `Ann2ToPlot`, `AnnParamToPlot`, `ShowPercent`, `ShowDifference`	what a multi part annotation shows
`AddToList(annotation)`, `InsertToList(index, annotation)`, `ClearList()`	child annotations, for a text of several lines

Member	Meaning
`AnnItems`, `AnnGroupList`	the annotations, or the groups, it holds
`AddGroup(group)`	adds a group inside this one
`RemoveAnnotation(annotation)`	removes an annotation
`Clear()`	removes everything
`Visible`	drawn or not
`Area`	chart area the group is bound to
`PlotForeground`	drawn over the bars
`MaxBarsViewed`, `MaxCountShown`	limits for drawing
`AnnPerBar`, `shiftIndex`, `OutBars`	for groups with a fixed number of annotations per bar: lets the chart find the visible ones without scanning the group

Only what an indicator sets is applied. See Axes and placement.

Member	Meaning
`YSame`	symmetric around zero
`YAdjust`, `YAuto`	the axis follows the visible values
`DecimalPlaceShown`, `FormatAutoNumber`, `CustomFormat`	format of the labels
