The RiverSoftAVG Charting Component Suite (RCCS) for Delphi and Appmethod (Object Pascal) is a free (for non-commercial use) with source charting Suite for adding charts and graphs to your programs. The RiverSoftAVG Charting Component Suite provides the following advantages:
•100% Source Code
•For VCL and FMX
•For Win32, Win64, OSX, iOS and Android
•Integrated IDE Help Insight as well as Help File and Online Documentation
•Chart Types: Area, Arrow, Bar, Sparse Bar, Line, Pie, Point, Shape, Graph (Flowchart), Equalizer, Guides, Chart-in-Chart, Path, Scatter, Donut Chart, Donut+, Bubble, High/Low/Average, and CandleStick
•Powerful Chart Functions Components transform Source chart values into Target chart values using over 15 functions (e.g., minimum, maximum, average, etc) grouped into periods (e.g., percentage of chart values; all values in same hour, day, week, etc).
Chart Function Example Showing automatic generation of hourly High/Low/Average from a Line Source Chart to a High/Low/Average Target Chart.
Example also shows the stand-alone TRSLegendListBox in the upper right (with TShadowEffect)
Two stand-alone Legend controls: Legend ListBox (TRSLegendListBox) allows controlling selection and visibility from the legend, and Legend Box (TRSChartLegendBox) Control allows displaying all values in a chart or panel (and applying effects in FMX).
•Display charts on chart panel (with integrated axes, legend, header, footers, etc) or stand-alone
•Supports FMX Effects (bevel, shadow, swirl, etc) and animations on charts (FMX Only)
•Data-Aware Chart Types (VCL Only)
•FREE for use in your non-commercial applications. A commercial license is available by one-time purchase (upgrades are free) or by submitting an accepted software component to be included into the RiverSoftAVG Charting Component Suite (see Licensing for details)
•Design-time definition of chart values
•Less confusing and programmer error prone
•Zoom, Pan, and Select Chart values
TRSChartInChart allows multiple embedded charts
•Change Visibility and Selected for each chart value (e.g., Hide a pie slice in a pie chart or react to the user selecting different points in a chart)
•Unique Chart-in-chart can display multiple embedded charts (similar to Picture-in-picture, where each value is another chart)
IMPORTANT: Please see Writing Cross-Library Code for more information about working with the RCCS after v3.0.
To use the RCCS, drop a TRSChartPanel component onto your form. The TRSChartPanel is the container for all of the charts you wish to display. Then, drop the TRSCustomChart component descendant onto the form and connect its Panel property to the chart panel. 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. Currently, the RCCS provides the following chart types:
•Area Chart (TRSAreaChart)
•Arrow Chart (TRSArrowChart)
•Bar Chart (TRSBarChart)
•Graph Chart (TRSGraphChart)
•Line Chart (TRSLineChart)
•Point Chart (TRSPointChart)
•Pie Chart (TRSPieChart)
•Shape Chart (TRSShapeChart)
•Equalizer Chart (TRSEqChart)
•Guides Chart (TRSGuideChart)
•Path Chart (TRSPathChart)
•Scatter Chart (TRSScatterChart)
•Sparse Bar Chart (TRSSparseBarChart)
There are also database variants for the VCL.
