Offset data sets on log-log axis?

Hi,

I have plotted muliple data sets on a scatter plot with log log axis. However, to make the data more clear to understand I would like to offset thes data sets.

How can I do this?

Thanks!

Could you provide a screen shot of your scatter plot and describe what you mean by offsetting the data?

Below is my plot, the points are plotted using

errorbar((x(:,1)),(x(:,2)),(x(:,3)))

and the solid lines using

plot(x(:,1),x(:,5))

Hi Hannah,

After you posted the plot I withdrew my answer since I realized I did not really understand the question. That puts this back in the queue of unanswered questions and makes it more noticeable to people.

The picture helps, Hannah. But it's still not clear how you'd like to offset the data. Do you mean you'd like to vertically shift some of the lines so there is vertical space along the y axis between the lines? That could open a can of worms. If I understood the ultimate goal I might be able to advise alternative solutions.

It's not a good practice since the viewer will no longer understand the true y value of your data and the relationship between your data points. Small differences in their shape will be more difficult to see.

Here's an alternative. What if you plotted all 3 lines on 3 different subplots (so each subplot contained all 3 lines) but each subplot featured only 1 of the lines by include the markers while the other 2 lines did not contain markers.

Hi,

So I have decided to scale each plot by a factor of 5 along the y axis i.e. plot one as it is, multiple one by 5 and the other by 25. This works for me as i am interested in comparing the shape of the curves rather than the y values.

I think for the purpose of comparing values, the subplot idea is the best solution.

Thank you all for the help!
