Name

Description

published property

AsDateTime

Provides access to the   Value property as a TDateTime value.

alert_noteNotes 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.

public property

AsDateTimes[Integer]

Represents property AsDateTimes[Integer].

published property

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.

public property

Collection

Specifies the RSChartPanel.TRSChartValues instance to which this Item belongs. Each TRSChartValue belongs to the TRSChartValues collection which creates it. The Collection property points to the collection object to which the value belongs.

published property

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 RSChartPanel.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.

published property

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.

alert_cautionImportant Note

This is an FMX only feature. Any value > 0 is drawn fully opaque in the VCL version

protected property

Options

Represents property Options.

published property

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)

public property

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.
 

published property

Tag

Provides user-defined storage that is associated with the value

published property

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).

alert_noteNotes to Inheritors

To change which dimension is returned by this Value, override the GetDefValue and     SetDefValue methods

public property

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.

alert_cautionCaution

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

public 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.

alert_cautionCaution

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.
 
 

published property

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.

protected property

X

Provide access to the first 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.

alert_noteNotes 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

protected property

XAsDateTime

Provide access to the first 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.

alert_noteNotes 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

protected property

Y

Provide access to the second 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.

protected property

YAsDateTime

Provide access to the second 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.

Remember to also publish the       XAsDateTime,       YAsDateTime, and       ZAsDateTime properties

protected property

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
