LinkTopAxisData

Adds a linked second x axis to a plot

Description

This function will add a second x axis to a plot with the top ticks at arbitrary positions (you are not limited to the bottom tick positions). The new axis is created behind the original axis, and the two axes are linked together. This gives a much more intuitive behaviour, for example clicking in the figure window will select the original axis. It also alows you to drag the plot around, resize the limits and change between a log/linear scale without having to update the dummy axis manually.

1. The example does not work (??? Undefined function or variable 'T')
2. This kind of submission typically requires a screenshot!

[Tim Richards]

Many thanks for your comment. I have changed the example and added a screenshot.

[Frederic Moisy]

Works well, very useful for me. Thanks!

[Thierry Dalon]

small bug:
line temp=temp(diff(temp(:,1))>0,:);
will always remove on tick label.

Thank you so much for this submission! It took me 15 minutes of playing around with it to figure it out (it wasn't immediately clear to me that TopTickPositions were the positions on the original axis and that TopTickLabels were the associated values on the new axis). But it works great! I really appreciate it - thanks!!
