QwtInterval¶
-
class
qwt.interval.QwtInterval(minValue=0.0, maxValue=-1.0, borderFlags=None)[source]¶ A class representing an interval
The interval is represented by 2 doubles, the lower and the upper limit.
-
class
QwtInterval(minValue=0., maxValue=-1., borderFlags=None)¶ Build an interval with from min/max values
Parameters: - minValue (float) – Minimum value
- maxValue (float) – Maximum value
- borderFlags (int) – Include/Exclude borders
-
QwtInterval.setInterval(minValue, maxValue, borderFlags)[source]¶ Assign the limits of the interval
Parameters: - minValue (float) – Minimum value
- maxValue (float) – Maximum value
- borderFlags (int) – Include/Exclude borders
-
QwtInterval.setBorderFlags(borderFlags)[source]¶ Change the border flags
Parameters: borderFlags (int) – Include/Exclude borders See also
-
QwtInterval.setMinValue(minValue)[source]¶ Assign the lower limit of the interval
Parameters: minValue (float) – Minimum value
-
QwtInterval.setMaxValue(maxValue)[source]¶ Assign the upper limit of the interval
Parameters: maxValue (float) – Maximum value
-
QwtInterval.isValid()[source]¶ A interval is valid when minValue() <= maxValue(). In case of QwtInterval.ExcludeBorders it is true when minValue() < maxValue()
Returns: True, when the interval is valid
-
QwtInterval.width()[source]¶ The width of invalid intervals is 0.0, otherwise the result is maxValue() - minValue().
Returns: the width of an interval
-
QwtInterval.normalized()[source]¶ Normalize the limits of the interval
If maxValue() < minValue() the limits will be inverted.
Returns: Normalized interval See also
-
QwtInterval.inverted()[source]¶ Invert the limits of the interval
Returns: Inverted interval See also
-
QwtInterval.contains(value)[source]¶ Test if a value is inside an interval
Parameters: value (float) – Value Returns: true, if value >= minValue() && value <= maxValue()
-
QwtInterval.unite(other)[source]¶ Unite two intervals
Parameters: other (qwt.interval.QwtInterval) – other interval to united with Returns: united interval
-
QwtInterval.intersect(other)[source]¶ Intersect two intervals
Parameters: other (qwt.interval.QwtInterval) – other interval to intersect with Returns: intersected interval
-
QwtInterval.intersects(other)[source]¶ Test if two intervals overlap
Parameters: other (qwt.interval.QwtInterval) – other interval Returns: True, when the intervals are intersecting
-
QwtInterval.symmetrize(value)[source]¶ Adjust the limit that is closer to value, so that value becomes the center of the interval.
Parameters: value (float) – Center Returns: Interval with value as center

Parameters: value (float) – Value Returns: true, if value >= minValue() && value <= maxValue()
-
QwtInterval.unite(other)[source] Unite two intervals
Parameters: other (qwt.interval.QwtInterval) – other interval to united with Returns: united interval
