    Hi All
    I have an assignment to plot a Log-Log Graph to find the gradient and Y-Intercept of a log-Log Graph, but I also have to add error bars to the graph, I have already calculated the uncertanties. One is +/-0.05 how would I add this to the graph? Do I need to take a log of this (Log0.05) and then use this for the error bar? Or is there another way to do it?

    Thnx in Advance

    Get it as a percentage error and apply that to the log-log graph. Equation is

     \frac{\sigma_L}{log x} = \frac{\sigma_x}{x}

    where  \sigma is the error on the quantity.
