How to use errorbar

I have a script with the following data Data2=importdata('MichaelisMenten.txt'); Conc=Data2(:,1); rate=Data2(:,2); spred=Data2(:,3); w=1./(spred.*spred); ' plot(rate,konc); errorbar(??);

I need make vertical segment at each measurment on my plot, which showes plus and minus spread (ussing errorbar). But i cant figure out what to put in the errorbar-code

The syntax that you are probably looking for is : errorbar(x,y,err) , where :

• x - data points for the x coordinate (in this case rate perhaps)
• y - data points for the y coordinate (in this case konc (conc?))
• err - error bar lengths (assuming you want symmetric bars)

The documentation gives a more exhaustive description of the various options that are available. You can take a look at the error bar documentation here: https://www.mathworks.com/help/matlab/ref/errorbar.html .
