TRSChart
|
Extends the FMX.RS.ChartPanel.TRSCustomChart component to publish its properties. All of the chart types in the RCCS either directly or indirectly descend from this class. The TRSChart component provides the common properties and methods for a chart type, including the HorizontalAxis and VerticalAxis to use for the chart, Caption and Font , and most importantly, the Values property.
The Values property is the most important property of a chart type and allows you to define the chart values at design-time or run-time. It provides all the information about an individual chart point, not only position but also Caption, Visibility, and Selected. Each chart type uses the FMX.RS.ChartPanel.TRSChartValues class appropriate to their chart type, e.g., a bar chart has a 1D value type, line charts have 2D value types, and shape charts use 2D value types with shape/image information.

TRSGuideChart
|
The TRSGuideChart component is a FMX.RS.ChartPanel.TRSCustomChart descendant that represents guides. Guides are horizontal or vertical lines, similar to Photoshop guides, that help the user more quickly see other chart values. A guide chart is meant to be used with other chart types to help users interpret the values. For example, you could create a horizontal guide at Y=100, which would display a horizontal line across the chart panel at Y=100. The user can then use this guide to see at a glance which values from a line chart are above or below 100.
Note that all guides share the same pen and brush of the chart. If you wish to have guides with different looks, drop a new TRSGuideChart on your form.

TRSPathChart
|
The TRSPathChart component is a FMX.RS.ChartPanel.TRSCustomChart descendant that represents a path chart. The path chart displays chart values ( FMX.RS.Charts.TRSPathChartValue) as irregular shapes defined by paths representing groups of connected curves and lines. Every value in the chart has its own path and maintains the coordinates of geometric shapes in world coordinate space in an array of path points. Each saved point has a specific type, to identify the primitive shape it is defining. Complex shapes of a TPathData are composed of a sequence of primitive shapes like lines and curves.
In addition to using code to define your path shape, each value has a Data property which accepts a string defining the shape. This string uses the same format as the TPath FMX component, which is also the same format as the paths defined in SVG files. To show SVG shapes, copy the paths to chart values.
Note: Most SVG shapes are defined assuming the 0, 0 point is in the top-left. You may need to invert the LeftAxis in order to see the path shape properly.

TRSPathChartValuesEnumerator
|
Represents type TRSPathChartValuesEnumerator.
|
|
TRSPieChart
|
The TRSPieChart component is a FMX.RS.ChartPanel.TRSCustomChart descendant that represents a pie chart. The Pie Chart displays each chart value ( FMX.RS.Charts.TRSPieChartValue) as a slice of the pie in the pie chart. The size of the slice is dependant on all the other slices in the pie chart, e.g., the size of a slice is proportional to the percentage that the pie slice's value is to the sum of all slices. The pie chart draws each slice starting from 3 o'clock position on a clock and goes counter-clockwise from there. Modify the Offset angle to change the starting angle.
Note that the pie chart always fills the rectangle between the axes on the chart panel, e.g., you cannot zoom in on a pie chart. You can, however, change the OuterRadius property to shrink the pie chart and the Origin property to move its center point.
