Output

string

PopCanvas

Input

boolean

False

If true, a Matplotlib canvas will be popped out , which contains the saved plot.

Description

Save 1D plots to a png file, as part of autoreduction. Multiple spectra in the same workspace will be represented by curves on the same plot. Groupped workspaces will be shown as subplots. If the workspace has more than one spectra, but less or equal to ten, labels will be shown.

Note

The figures contain lines between points, no error bars.

Note

Requires matplotlib version>= 1.2.0

Usage

#create some workspaces
CreateWorkspace(OutputWorkspace='w1',DataX='1,2,3,4,5,1,2,3,4,5',DataY='1,4,5,3,2,2,3,1',DataE='1,2,2,1,1,1,1,1',NSpec='2',UnitX='DeltaE')
CreateWorkspace(OutputWorkspace='w2',DataX='1,2,3,4,5,1,2,3,4,5',DataY='4,2,5,3,3,1,3,1', DataE='1,2,2,1,1,1,1,1',NSpec='2',UnitX='Momentum',VerticalAxisUnit='Wavelength',VerticalAxisValues='2,3',YUnitLabel='Something')
wGroup=GroupWorkspaces("w1,w2")

#write to a file
try:
    import mantid
    filename=mantid.config.getString("defaultsave.directory")+"SavePlot1D.png"
    SavePlot1D(InputWorkspace=wGroup,OutputFilename=filename)
except:
    pass

Output:


The file should look like

SavePlot1D.png

Usage in autoreduction

# create some workspaces
CreateWorkspace(OutputWorkspace='w1',DataX='1,2,3,4,5,1,2,3,4,5',DataY='1,4,5,3,2,2,3,1',DataE='1,2,2,1,1,1,1,1',NSpec='2',UnitX='DeltaE')
# get the div html/javascript for the plot
div = SavePlot1D(InputWorkspace='w1', OutputType='plotly')
from postprocessing.publish_plot import publish_plot
request = publish_plot('TESTINSTRUMENT', 12345, files={'file':div})
print("post returned {}".format(request.status_code))

To see what the result looks like on your local system, add the Filename argument (.html extension) and change to OutputType='plotly-full'.
