Clones the input MatrixWorkspace(s) and orders the x-axis in an ascending or descending fashion.
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | MatrixWorkspace | Mandatory | Input Workspace |
| OutputWorkspace | Output | MatrixWorkspace | Mandatory | Sorted Output Workspace |
| Ordering | Input | string | Ascending | Ascending or descending sorting. Allowed values: [‘Ascending’, ‘Descending’] |
Clones the input Matrix Workspaces and orders the x-axis in an ascending or descending fashion. Ensures that the y-axis and error data as well as optional Dx data are sorted in a consistent way with the x-axis.
This algorithm is for use with either point data based workspaces or histogram based workspaces. It is particularly suitable for reformatting workspaces loaded via LoadAscii.
#Import requirements
import numpy as np
# Create the workspace
dataX = [2., 1., 3.]
dataY = [2., 1., 3.]
dataE = [2., 1., 3.]
ws = CreateWorkspace(DataX=dataX,DataY=dataY,DataE=dataE,UnitX='TOF',Distribution=True)
# Print out the "Unordered X Axis"
print("Unordered Print")
print(ws.readX(0))
print(ws.readY(0))
print(ws.readE(0))
# Sort the X Axis in a Descending fashion
ws = SortXAxis(InputWorkspace='ws', Ordering='Descending')
print("In order print: Descending")
print(ws.readX(0))
print(ws.readY(0))
print(ws.readE(0))
# Sort the X Axis in a Ascending fashion
ws = SortXAxis(InputWorkspace='ws', Ordering='Ascending')
print("In order print: Ascending")
print(ws.readX(0))
print(ws.readY(0))
print(ws.readE(0))
Output:
Unordered Print
[ 2. 1. 3.]
[ 2. 1. 3.]
[ 2. 1. 3.]
In order print: Descending
[ 3. 2. 1.]
[ 3. 2. 1.]
[ 3. 2. 1.]
In order print: Ascending
[ 1. 2. 3.]
[ 1. 2. 3.]
[ 1. 2. 3.]
