Descripción detallada
A scale map.
QwtScaleMap offers transformations from a scale into a paint interval and vice versa.

void QwtScaleMap::setPaintInterval |
( |
int |
p1, |
|
|
int |
p2 |
|
) |
| |
Specify the borders of the paint device interval.
- Parámetros:
-
p1 | first border |
p2 | second border |
void QwtScaleMap::setPaintXInterval |
( |
double |
p1, |
|
|
double |
p2 |
|
) |
| |
Specify the borders of the paint device interval.
- Parámetros:
-
p1 | first border |
p2 | second border |
void QwtScaleMap::setScaleInterval |
( |
double |
s1, |
|
|
double |
s2 |
|
) |
| |
Specify the borders of the scale interval.
- Parámetros:
-
s1 | first border |
s2 | second border |
- Atención:
- logarithmic scales might be aligned to [LogMin, LogMax]
Initialize the map with a transformation
int QwtScaleMap::transform |
( |
double |
s | ) |
const [inline] |
Transform a point related to the scale interval into an point related to the interval of the paint device and round it to an integer. (In Qt <= 3.x paint devices are integer based. )
