This is the deal-breaker for me. I cannot use this great-looking graphing library without that very basic engineering and scientific mode. Many natural data-sets require a log scale axis. Sound/hearing is a great example. Thanks!

How awesome would that be... really need to display my vacuum measurements ...

This would be invaluable.

We have implemented Logarithmic Axes on HighCharts. Have a look at: http://www.fusioncharts.com/PowerCharts/gallery/#logarithmic

Let us know your feedback.

We really need this for a project that uses extreme number ranges.

Great idea - we could really use it.

This would also critical for use on our project.

Logarithmic axes should be a basic feature for any decent charting software.
I am working for a telecom company and this single feature is the only showstopper for us starting using this excellent software.
Please consider moving this higher up on the priority list!

We have teh same issue. Most of the values we have are in millions but there are a couple that are in billions that is making the chart unreadable

I have data that has low average values but occasional spikes greater than 10 times the normal values, this tends to destroy the graphs. A logarithmic option would rock! :) Thanks

It will be the a great addition to this brilliant JS package.
