Member Function Documentation
| virtual bool MAKLogger::DtProgressiveLineGraph::autoScale | ( | ) | const [virtual] |
Get whether auto scaling is used.
Auto scale will change the range dynamically as points are added.
| virtual void MAKLogger::DtProgressiveLineGraph::drawAsVerticalLines | ( | bool | useVerticalLines | ) | [virtual] |
Set whether vertical line samples are used instead of connected samples.
| virtual void MAKLogger::DtProgressiveLineGraph::offsetPercentages | ( | double | percentOffset | ) | [virtual] |
Offset the percentages of all the values.
Any value with a negative percentage or a percentage > 100 will be dropped.
| virtual void MAKLogger::DtProgressiveLineGraph::offsetPercentages | ( | int | set, |
| double | percentOffset | ||
| ) | [virtual] |
Offset the percentages of a set of values.
Any value with a negative percentage or a percentage > 100 will be dropped.
| virtual void MAKLogger::DtProgressiveLineGraph::setAutoScale | ( | bool | value | ) | [virtual] |
Set whether auto scaling is used.
Auto scale will change the range dynamically as points are added.
| void MAKLogger::DtProgressiveLineGraph::setModel | ( | DtLgrGuiModel * | myModel | ) |
Set the model, this is required for a number of features such as drawing a cursor.
| virtual void MAKLogger::DtProgressiveLineGraph::setRange | ( | int | min, |
| int | max | ||
| ) | [virtual] |
Sets the minimum and maximum range of the points.
As points are scaled clipped to the min and max. when drawn.
| virtual bool MAKLogger::DtProgressiveLineGraph::usesVerticalLines | ( | ) | const [virtual] |
Get whether vertical line samples are used instead of connected samples.
