Errorbars in a dataset
Posted:

Does anyone know how to plot errorbars on a line graph from data stored in a dataset?
If I store the data in an array I can produce the graph with the following code:
c7data=xlsread('TFangleTOP.xls'); c7MEAN=mean(c7data); c7SD=std(c7data); c7SEM=c7SD./length(c7SD); s2data=xlsread('TFangleBOTTOM.xls'); s2MEAN=mean(s2data); s2SD=std(s2data); s2SEM=s2SD./length(s2SD); errorbarLOWERzeros = [0 0 0 0]; errorbarUPPERzeros = [0 0 0 0]; xAXIS = [1 2 3 4]; errorbar(xAXIS,c7MEAN,errorbarLOWERzeros, c7SEM,':bo')
However if I store the data in a dataset in the following approach:
ds1 = dataset('xlsfile', 'Ltrap.xls');
I can plot the data using:
datasetfun(@plot,ds1,'DataVars','Fmean')
but I can't seem to figure out how to get errorbars on the chart.
Any help will be greatly appreciated. Many thanks Dan
