The XYDataSet Object¶
-
class
qexpy.data.XYDataSet(*args, **kwargs)[source]¶ A pair of ExperimentalValueArray objects
QExPy is capable of multiple ways of data handling. One typical case in experimental data analysis is for a pair of data sets, which is usually plotted or fitted with a curve.
- Parameters
xdata (List|np.ndarray) – an array of values for x-data
ydata (List|np.ndarray) – an array of values for y-data
- Keyword Arguments
xerr (Real|List) – the uncertainty on x data
yerr (Real|List) – the uncertainty on y data
xunit (str) – the unit of the x data set
yunit (str) – the unit of the y data set
xname (str) – the name of the x data set
yname (str) – the name of the y data set
Examples
>>> import qexpy as q
>>> a = q.XYDataSet(xdata=[0, 1, 2, 3, 4], xerr=0.5, xunit="m", xname="length", >>> ydata=[3, 4, 5, 6, 7], yerr=[0.1,0.2,0.3,0.4,0.5], >>> yunit="kg", yname="weight") >>> a.xvalues array([0, 1, 2, 3, 4]) >>> a.xerr array([0.5, 0.5, 0.5, 0.5, 0.5]) >>> a.yerr array([0.1, 0.2, 0.3, 0.4, 0.5]) >>> a.xdata ExperimentalValueArray([MeasuredValue(0.0 +/- 0.5), MeasuredValue(1.0 +/- 0.5), MeasuredValue(2.0 +/- 0.5), MeasuredValue(3.0 +/- 0.5), MeasuredValue(4.0 +/- 0.5)], dtype=object)
