SavePlot1DAsJson v1#

Summary#

Plottable data file in Json format

Properties#

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	Workspace that contains plottable data
JsonFilename	Input	string	Mandatory	Name of the output Json file. Allowed extensions: [‘.json’]
PlotName	Input	string		Name of the output plot

Description#

This algorithm is to extract plottable 1-D dataset(s) with metadata from a MatrixWorkspace, serialize it into json format, and dump the result to a file.

It currently only support MatrixWorkspace

Note for usage with ORNL live monitor: The output file needs to be named <inst>_<runnumber>_plot_data.json to be cataloged and plotted.

Usage#

Example:

import os, numpy as np
# prepare input
E = np.arange(-50, 50, 10.0)
I = 1000 * np.exp(-E**2/10**2)
err = I ** .5
dataws = CreateWorkspace(
    DataX = E, DataY = I, DataE = err, NSpec = 1,
    UnitX = "Energy")
# output path
out_json = "myplot.json"
# run algorithm
SavePlot1DAsJson(InputWorkspace=dataws, JsonFilename=out_json, PlotName="myplot")
