This property controls whether the chart will be drawn directly to the graphics device (true) or using an off-screen image buffer (false). Set this property to false when the drawing speed of the chart seems very slow. When this property is set to false, it can increase the drawing speed by a factor of three in some situations. |
||
Data Type: |
Boolean |
|
Range: |
true / false |
|
true= |
Draw directly to graphics device |
|
false= |
Use off screen image buffer |
|
Default: |
true |
|
Syntax: |
setUseOffScreen ( true| false ); |
|
boolean = getUseOffScreen (); |
This property enables (true) / disables (false) the use of a sample data in a chart.. |
||
Data Type: |
Boolean |
|
Range: |
true / false |
|
true= |
Use sample data |
|
false= |
Do not use sample data. Use the data provided by the setData() methods or other data interface |
|
Default: |
true |
|
Syntax: |
setUseSampleData ( true | false ); |
|
boolean = getUseSampleData(); |
||
Example: |
perspective1.setUseSampleData(false); |
|

Notes: |
If this property is set to false, your application must provide all property settings (including the GraphType) and all data values that define the chart. |
This property enables/disables the use of the riser border color set by the SeriesDefaultBorderColor property or transparent borders set by SeriesDefaultTransparentBorderColor. When this property is enabled (true) and SeriesDefaultTransparentBorderColor is disabled (false), all riser borders are drawn with the SeriesDefaultBorderColor. When this property is enabled (true) and SeriesDefaultTransparentBorderColor is enabled (true), all riser borders are transparent (i.e., they are drawn with the same color as the riser's fill color). When this property is disabled (false), black riser borders are used unless specifically changed by another Perspective method (i.e., setSelectionBorderColor, setSeriesBorderColor(), etc.).. |
||
Data Type: |
Boolean |
|
Range: |
true / false |
|
true= |
If SeriesDefaultTransparentBorderColor is false, use the SeriesDefaultBorderColor for riser borders. If SeriesDefaultTransparentBorderColor is true, make the riser borders transparent. |
|
false= |
Draw black riser borders or color defined by other Perspective methods (e.g., setSelectionBorderColor(), setSeriesBorderColor(), etc.). |
|
Default: |
false |
|
Syntax: |
setUseSeriesBorderDefaults( true | false ); |
|
boolean = getUseSeriesBorderDefaults(); |

This property enables/disables the use of different shapes for each series in the legend area. |
||
Data Type: |
Boolean |

|
false= |
Use a square box for each legend icon |
|
Default: |
false |
|
Syntax: |
setUseSeriesShapes ( true | false ); |
|
boolean = getUseSeriesShapes(); |

Example: |
perspective1.setUseSeriesShapes(true); |
