I haven't used this for log scales, but using the exponents (e.g. -12 to -6) should provide plausible, if not optimal, results. You're right that for log scales, non-integer numbers are much less nice than for standard scales. You would have to adjust the niceness score to account for this.

You can make this happen by simply checking if the minimum and maximum labels are outside the range of the data in the optimization search. The R implementation I provided has an option to do this check already. Look there for more details. On part 2 of you question, it sounds like you want to force external labels.

You can increase the weight on this term if you like. The simplicity component of the optimization score includes a term for whether or not the labeling includes 0.

I have found that in some types of charts it looks weird if the zero value along the y axis is not displayed. This is the case for the bar chart, amongst others, specially if you have both positive and negative values. I know it is possible to tweak the settings, but this will depend on the data ranges being assigned. If anyone would like to share information on how this could be achieved predictably, independent of the other settings, I would be immensely grateful.

I have a question regarding the actual usage of your algorithm in two specific cases: 1) When using datasets that are both positive and negative, I want to somehow force the zero value on the y axis to be displayed as a label. Right now, this depends on the many settings available to you, but if you could give me a hint on how to force the zero value to be displayed, independent on the other settings, and from there on, calculate the rest of the labels. 2) When using a bar chart, many times the least value is displayed as a bar that's not visible. Take for example a data set that goes from 5 to 10. The y axis could potentially be defined by labels going from 5 through 10, which would render the smallest bar (with a value of 5) as non visible. Ideally in the case of bars, I would like to see all bars that are greater than zero. In this case the labels could potentially go from 2 through 10 or something similar, giving the smallest bar some space. For this situation, I would like to have a way to force the first label be lesser than the smallest value. Maybe these two cases are properly handled by your algorithm, but I haven't been able to find how to predictively handle this, without prior knowledge of the data. If these cases are not handled, I would love if you could either give me hints on how this can be implemented or maybe add these two functionalities to the algorithm, so that bar charts can be implemented with the labeling being adjusted to these two conditions.

I have see numerous references to R before but this is the first time i have played with it. have you attempted to apply any of this to log scales? (i simply tried each one and using the actual values 1.0e-12 to 1.0e-6 did not work and trying -12 to -6 sometimes gives me non integer exponents). thanks very interesting work. i have implemented the majority of your stuff in matlab and if interested will send you a copy (each method extended, wilkinson… are separate functions) if you are interested.

I was learning C# while writing this and I may have overused that language feature. Let me know if I can clarify anything. Perhaps so.

I was wondering if there is a Java implementation might be available sometime soon, or I should try to port the C# version myself. Also wondering if Ahmet Karahan has finished his Java implementation and if he is willing to share it. Thanks! Hi,
