SavePlot1DAsJson dialog.

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")
