TRSChartDataLink
|
Provides a data-aware link for the TRSChart and its descendants. Since this data link is being used in multiple descendants, it does most of the work so that little extra code is written in each chart type. The events are for unexpected uses.
 Note
|
DataFields holds the field names associated with each *dimension* in the TRSChartValue internal array PLUS one. The last index holds the Caption's FieldName
|
 Notes to Callers
|
Data-aware charts use the TRSChartDataLink to provide a mapping of data field names to their Values dimension. They should expose properties that allow the user to input dataset field names for each dimension of their TRSChartValue.Values property. These field names would be placed in DataFields property.

Unlike the normal Donut Chart ( TRSDonutChart ), the TRSDonutChartEx allows full control of donut pieces (OuterRadius, InnerRadius, StartAngle, Sweep Angle) at the cost of extra bookkeeping for the user, i.e., the TRSDonutChartEx does not track the percentage that each donut piece takes in the entire donut chart.

TRSDBGuideChart
|
The TRSGuideChart component is a 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.
The values for the chart are created by reading a dataset (database table or query) specified with the DataSource property. Each record in the dataset provides one value for the chart, where the DataFieldX property specifies the field to use for the X property of the Value and the DataFieldY property specifies the Y property of the Value.

The High/Low/Average Bar Chart displays each chart value ( TRSHighLowAverageChartValue ) as a vertical or horizontal bar (depending on Orientation). A HighLowAverage chart is something like a combination of a line-chart and a bar-chart: each bar represents three important pieces of information: the Average (as line on side of bar), and the high and the low. Each value draws a separate bar and the order of the bars is based on the order of the TRSHighLowAverageChartValue in the collection.
The values for the chart are created by reading a dataset (database table or query) specified with the DataSource property.

TRSDBPathChart
|
The TRSDBPathChart component is the database aware version of the TRSPathChart . The TRSPathChart component is a TRSCustomChart descendant that represents a path chart. The path chart displays chart values ( 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.
The values for the chart are created by reading a dataset (database table or query) specified with the DataSource property. Each record in the dataset provides one value for the chart, where the DataFieldX property specifies the field to use for the X property of the Value, the DataFieldY property specifies the Y property of the Value, etc.
 Important Note
|
Unlike other charts, the path chart fetches data from one record only and creates one value only; it is assumed that one field of the record will hold the entire path.
|
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.

|
TRSDBPieChart
|
The TRSDBPieChart component is the database aware version of the TRSPieChart . The TRSPieChart component is a TRSCustomChart descendant that represents a pie chart. The Pie Chart displays each chart value ( 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.
The values for the chart are created by reading a dataset (database table or query) specified with the DataSource property. Each record in the dataset provides one value for the chart, where the DataField property specifies the field to use for the Value property of the Slice Value.

TRSPathChartDataLink
|
Povide a data-aware link for the RSDBCharts.TRSDBPathChart .
Important Note
|
Unlike other charts, the path chart fetches data from one record only and creates one value only; it is assumed that one field of the record will hold the entire path.
|
Note
|
DataFields holds the field names associated with each *dimension* in the TRSChartValue internal array plus two. The last index holds the Caption's FieldName. The first index holds the path data
|
Notes to Callers
|
Data-aware path charts use the TRSPathChartDataLink to provide a mapping of data field names to their Values dimension. They should expose properties that allow the user to input dataset field names for each dimension of their TRSChartValue.Values property. These field names would be placed in DataFields property.
