Title: Plotting rate law graphs on Excel.
Post by: spankythehippo on January 14, 2012, 06:58:56 AM

OK. So I need to polish up my excel skills. This thread probably isn't the place to do it, but any answer will be appreciated.

I need to plot log₁₀ d[I²]/dt  vs log₁₀ [I^-]

Now, all my values are negative, so when I plot them on Excel, the axes are postioned in a way that it is the 3rd (negative) quadrant of a Cartesian plane. I need the graph to look like a normal graph, but no matter what I spam into Excel, the graph looks the same.

How can I fix this?

Long ago that I am not an Excel user, but you would go to graphics properties and modify the origin of the axis to change their position.

If you cannot do that and if as you say, all your values are negative, why do not just represent minus the values?
