|
1) Class Includes added
|
|||
|
|
|
|||
|
|
Include files, that match the class names are available now. So
|
|||

4) Spline interpolation
|

|||
|
|
|
|||
|
|

|
|||
|
|
for huge datasets with increasing x or y values
|
|||
|
|
|
|||
|
|
- QwtPlotCurve::closestPoint is virtual now
|
|||

- QwtPlotCurve::setLegendAttributes added
|
|||
|
|

|
|||

|
|||
|

|
|||
|
|

|
|||
|
|
|
