Sumary
| Name | Internal Name | Type | Description |
| Expression | Expression | WideString | Expression, the result of evaluating the expression will be included in the chart data for each record, if the data is not record based you can use the expression evaluator functions for charts with the identifier property of the chart to enter the desired values to the chart data |
| Identifier | Identifier | String |
If you assign a identifier string, the identifier is included in the expression evaluator namespace, this is useful to add values to the chart (or clear them) using expression evaluator functions for charts. |
| Chart Type | ChartType | TRpChartType | Chart type, the native driver only supports the Line type, Teechart supports all of them |
| Get V.Cond | GetValueCondition | WideString | Expression indicating when to get a value (for each record the engine will insert a value if expression property is set) |
| Serie Change exp. | SerieChangeExpressoin | WideString | Expression to determine a serie change, evaluated for each record if expression property is set |
| Bool S.Change | BoolSerieChange | Boolean | Indicates if the change serie expression must be processed as a boolean value (true) or as a value that can change and the change of a serie must coincide with expression value change (just like group expressions) |
| Clear Expression | ClearExpression | WideString | Like Serie change but to determine when to clear the values |
| Bool C. Esp. | BoolClearExpression | Boolean | Indicates if the clear expression must be processed as a boolean value (true=clear) or as a value that can change and the change of the balue foces the clear of the chart values |
| Caption Exp | CaptionExpression | WideString | If expression property is set, for each record a value is entered into the chart, the caption of the value is get evaluating this expression |
| Driver | Driver | TRpChartDriver | Default driver will get TeeChart in Windows and Native in Linux (to avoid Qt libs dependence and because it's not included by default in Kylix), you can force to use any driver, Teechart is only available if Teechart have been compiled into the engine. |
| View3d | View3d | Boolean | View the chart as 3d chart (Teechart only) |
| 3dWalls | View3dWalls | Boolean | Draw the walls with a 3d effect (Teechart only) |
| Perspective | Perspective | Integer | Perpective value for Teechart |
| Elevation | Elevation | Integer | Elevation value for Teechart |
| Rotation | Rotation | Integer | Rotation value for Teechart |
| Orthogonal | Orthogonal | Boolean | Orthogonal value for Teechart |
| Zoom | Zoom | Integer | Zoom value for Teechart |
| H.Offset | HorzOffset | Integer | Horizontal displacement for Teechart |
| V.Offset | VertOffset | Integer | Vertical displacement for Teechart |
| Tilt | Tilt | Integer | Tilt value for Teechart |
| Resolution(dpi) | Resolution | Integer | Dots per inchess for drawing the chart (Teechart), choose a value from 100 for low quality (less size) to 400 for high quality (more size) |
| Multibar | Multibar | TRpMultibar | Multibar value for Teechart |
| Show Hint | SHowHint | Boolean | Show a mark with the value inside the drawing |
| Show Legend | Showlegend | Boolean | Show chart legend |
| Mark style | MarkStyle | Integer | Select a mark style, value, percent... |
| Font Size V.Axis | HorzFontSize | Integer | Font size, horizontal axis texts |
| Font Rot.V.Axis | HorzFontRotation | Integer | Font rotation, horizontal axis texts |
| Font Size H. Axis | VertFontSize | Integer | Font size, vertical axis texts |
| Font Rot. H.Axis | HorzFontRotation | Integer | Font rotation horizontal axis texts |
| Color Expression | ColorExpression | WideString | A expression can be assigned, the result should be an integer value, that will be used as the color for the current value added to the chart |
| Serie Color Expression | SerieColorExpression | WideString | A expression can be assigned, the result should be an integer value, that will be used as the color for the current serie added to the chart |
| Y Axis Auto | AutoRange | Enumeration | Default, defines old behaviour, Auto adjunts Y axis to the provided values, Auto Max defines only automatic maximum value, Auto Min defines only the minium automatic value |
| Y Axis Min | YAxisMin | Double Precision | If Y Axis Auto has values of AutoNone or Auto Max, this value is used as the start of Y Axis |
| Y Axis Max | YAxisMaxn | Double Precision | If Y Axis Auto has values of AutoNone or Auto Min, this value is used as the end of Y Axis |
Aditional details about the implementation
Because Report Manager driver architechture, the chart output is processed diferently for each driver, the drivers not supporting charts are Excel and Plain Text driver. Printreptopdf command line tool does not support Teechart (nice charts) because it does not requires an X-Server. To generate pdf files or metafiles (with nice charts), from command line use printrep command line instead
