@@ -14,6 +14,7 @@ NEW any2many: an attempt to write the universial musr-data-file converter. Just
 NEW musrt0: added the possibility to show the t0 saved in the data file 's'. Furthermore added the option
     --getT0FromPromptPeak, -g with <firstGoodBinOffset>: will, in non-interactive mode estimate the t0's from 
     the prompt peak and write it into the msr-file (MUSR-133).
+FIXED plotting issues described in (MUSR-174).    
 FIXED accidental casting of a NULL pointer in msr2data
 FIXED crash of musrfit if a run-data-files is not found (MUSR-176)
 FIXED corrected time resolution for WKM from (ns) -> (us)
