    Is it possible to plot a graph of ln(y) against x, on autograph 3.3?

    Thank you very much.

    Type x = ln y.

    Type x = ln y.
    Thank you.

    If that is possible, why is it not possible to plot a graph of lny=((-6610)/120000)+ln(90), for example?

    Thank you.

    That is invalid. Where is the x term? If you are trying to draw a horizontal line then use the form y = something.

    Sorry! I meant lny=((-6610x)/120000)+ln(90).

    Just typed exactly that into Autograph and it graphed perfectly.

    Ok thank you. It isn't working on mine; I had, in fact, plotted it on autograph 3.2 a while ago, but cannot on autograph 3.3.

    Thank you for your help.

    I'm using 3.3. Are you sure you have your axes the right size? Did you zoom out?

    Yes. It didn't work when I had 6610.49 rather than 6610. No graph appeared. However, it now works for both, having tried the rounded value.

    Thank you very much!

    Moreover, how do you get lny on the vertical axis?

    Thank you.

    I don't know if Autograph does logarithmic scales. Excel does though so just use that!
