Description
|
|
Alignment
|
Specifies the location of the Caption within the 2D boundaries of the shape. Use the Alignment property to position your text within the shape.
|
|
AsDateTime
|
Provides access to the Value property as a TDateTime value.
 Notes to Inheritors
|
Usually this property provides access to the first dimension (X) of the value array. However, descendant classes can change which dimension this property accesses.
|
|
|
AsDateTimes[Integer]
|
Represents property AsDateTimes[Integer]. (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Brush
|
Specifies the color and pattern for filling the shape. Set the Brush property to specify the color and pattern to use when drawing the background or filling in the shape. The value of Brush is a TBrush object. Set the properties of the TBrush object to specify the color and pattern or bitmap to use when filling in the shape on the canvas.
|
|
Caption
|
Provides a caption or description of the chart value. This value will only be drawn if coLabelEachPoint is in the chart's Options property. (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Collection
|
Specifies the FMX.RS.Charts.TRSShapeChartValues instance to
which this Item belongs. Each collection item belongs to the
collection which creates it. The Collection property
points to the collection object to which the value belongs.
|
|
Color
|
Specifies the color of this individual value, e.g., the color of the bar or the point or the shape. When coColorEachPoint is in the FMX.RS.ChartPanel.TRSCustomChart.Options property, this color is drawn by the chart. When coColorEachPoint is not in the the Options property, the Color of the chart is used. (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Font
|
Specifies the font used to draw each shape's Caption. Set Font to specify the font to use for writing text. The value of Font is a TFont object. Set the properties of the TFont object to specify the font face, color, size, style, and any other aspects of the font.
|
|
Height
|
The Height and Width properties specify the size of the shape. Set Height or Width to change the size of the shape. Using the X, Y, Width and Height properties, you specify the exact rectangle where the shape will be drawn.
 Note
|
You can also use the Radius property to specify the size of the shape.
|
|
|
ImageIndex
|
Specifies the index of the image to use when drawing the point/image. When the FMX.RS.Charts.TRSPointChart component draws this point, it will use the specified image from its ImageList. The image is stretched to fit the PointsInfo width and height. To not use an image, set ImageIndex to -1. (Inherited from FMX.RS.Charts.TRS2DImageChartValue.)
|
|
Opacity
|
Specifies the opacity of the value when drawn. The opacity is a value between 0 (invisible) and 1 (fully opaque). Any value in-between controls the transparency of the value.
 Important Note
|
This is an FMX only feature. Any value > 0 is drawn fully opaque in the VCL version
|
|
|
Options
|
Represents property Options. (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Pen
|
Specifies the kind of pen the shape chart value uses for outlining the shape. Set Pen to specify the pen to use for outlining the shape. The value of Pen is a TRSPen object (TPen in VCL and TStrokeBrush in FMX). Set the properties of the TRSPen object to specify the color, style, width, and mode of the pen.
|
|
Radius
|
The Radius property is another way (besides using Width and Height ) of specifying the size of the shape. The Radius equals Sqr(Width) + Sqr(Height). Use the Radius if you need to specify size using a radius.
|
|
Scale
|
Specifies the scale factor for the value. A scale factor of 1 (default) draws the value at its normal size within the chart. Change the scale factor to shrink or grow the value within the chart (for drawing purposes only) (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Selected
|
Determines whether the chart value is selected. Use the Selected property to select or deselect a chart value. Selected chart values are displayed with the SelectionColor of the chart panel.
(Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Style
|
Defines the geometric shape of the shape value. The shape is drawn as large as possible within the bounding rectangle.
|
|
Tag
|
Provides user-defined storage that is associated with the value (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Value
|
Returns the main (or only) dimension in a chart value - which dimension is returned is based on the chart type. A chart value, depending on the chart type, can contain 1 or more dimensional values that define the chart value.
For example, each chart value in a bar chart contains 1 value (defining the height of the bar), line chart values contains 2 dimensions: X and Y, and shape chart values contain 4 dimensions: X, Y, Width, and Height. The ValueCount property returns the number of dimensions in the chart value. Use the Values property to access each dimension in the chart value (Note that TRSChartValue descendant classes expose properties, such as X and Y, which are safer to access the specific dimension of the value. You should not count on a specific dimension index to contain a specific property).
Notes to Inheritors
|
To change which dimension is returned by this Value, override the GetDefValue and SetDefValue methods
|
|
|
ValueCount
|
Returns the number of dimensions in the chart value. A chart value, depending on the chart type, can contain 1 or more dimensional values that define the chart value.
For example, each chart value in a bar chart contains 1 value (defining the height of the bar), line chart values contains 2 dimensions: X and Y, and shape chart values contain 4 dimensions: X, Y, Width, and Height.
Use the Values property to access each dimension in the chart value. The Value property in comparison returns the main (or only) dimension in a chart value - which dimension is returned is based on the chart type.
Caution
|
Note that TRSChartValue descendant classes expose properties, such as X and Y, which are safer to access the specific dimension of the value. You should not count on a specific dimension index to contain a specific property
|
|
|
Values[Integer]
|
Returns the value for the dimension in the chart value. A chart value, depending on the chart type, can contain 1 or more dimensional values that define the chart value.
For example, each chart value in a bar chart contains 1 value (defining the height of the bar), line chart values contains 2 dimensions: X and Y, and shape chart values contain 4 dimensions: X, Y, Width, and Height.
Use the Values property to access each dimension in the chart value. The Value property in comparison returns the main (or only) dimension in a chart value - which dimension is returned is based on the chart type.
Caution
|
Note that TRSChartValue descendant classes expose properties, such as X and Y, which are safer to access the specific dimension of the value. You should not count on a specific dimension index to contain a specific property
|
The ValueCount will equal the DimensionCount of the collection.
|
|
Visible
|
Determines whether the chart value is visible or not. Use the Visible property to change the visibility of the chart value. Even if the Visible property is True, the chart value may still not be visible if the chart axis is zoomed. (Inherited from FMX.RS.ChartPanel.TRSChartValue.)
|
|
Width
|
The Height and Width properties specify the size of the shape. Set Height or Width to change the size of the shape. Using the X, Y, Width and Height properties, you specify the exact rectangle where the shape will be drawn.
Note
|
You can also use the Radius property to specify the size of the shape.
|
|
|
X
|
Represents property X. (Inherited from FMX.RS.Charts.TRS2DImageChartValue.)
|
|
XAsDateTime
|
Represents property XAsDateTime. (Inherited from FMX.RS.Charts.TRS2DImageChartValue.)
|
|
Y
|
Represents property Y. (Inherited from FMX.RS.Charts.TRS2DImageChartValue.)
|
|
YAsDateTime
|
Represents property YAsDateTime. (Inherited from FMX.RS.Charts.TRS2DImageChartValue.)
|
|
Z
|
Provide access to the third dimension of the Values property formatted as a TDateTime. The XAsDateTime, YAsDateTime, and ZAsDateTime properties provide access to the first three dimensions of the Values property formatted as a TDateTime
Notes to Inheritors
|
These properties have protected visibility in the class, but descendant classes (e.g., RSCharts|TRS2DChartValue and TRS3DChartvalue ) publish the properties to provide more explanatory access to the dimensions of the Values property.
Remember to also publish the X, Y, and Z properties
|
|
|
ZAsDateTime
|
Provide access to the third dimension of the Values property. The X, Y, and Z properties provide access to the first three dimensions of the Values property.
Use the X, Y, and Z property to access the coordinates of a point.
Notes to Inheritors
|
These properties have protected visibility in the class, but descendant classes (e.g., RSCharts|TRS2DChartValue and TRS3DChartvalue ) publish the properties to provide more explanatory access to the dimensions of the Values property.
Remember to also publish the XAsDateTime, YAsDateTime, and ZAsDateTime properties
