Usage

Example - Merge 2 sample logs with value reset:

Load(Filename=r'HYS_11092_event.nxs',OutputWorkspace='HYS_11092_event')
MergeLogs(Workspace='HYS_11092_event',LogName1='Phase1',LogName2='Phase2',MergedLogName='PhaseM12',ResetLogValue='1',LogValue1='1',LogValue2='2')
ws = mtd["HYS_11092_event"]
newprop = ws.run().getProperty("PhaseM12")
prop1 = ws.run().getProperty("Phase1")
prop2 = ws.run().getProperty("Phase2")

print("Phase 1's size = {}, Phase 2's size = {}, Merged size = {}.".format(prop1.size(), prop2.size(), newprop.size()))
for i in range(5):
    print("Phase1              Time[{}] = {}.".format(i, prop1.nthTime(i)))
for i in range(5):
    print("Phase2              Time[{}] = {}.".format(i, prop2.nthTime(i)))
for i in range(5):
    print("Mixed Phase 1 and 2 Time[{}] = {}.".format(i, newprop.nthTime(i)))

Output:

Mixed Phase 1 and 2 Time[1] = 2012-08-14T18:55:52.390000000 .
Mixed Phase 1 and 2 Time[2] = 2012-08-14T18:55:52.406000000 .
