How to Do a Logarithmic Graph 
by br0wn in Hobbies, Games & Toys 

Plotting a logarithmic graph is similar to graphing any other mathematical
function. A logarithmic point consists of both an independent variable,
which is the inputted value, and a dependent variable, which is the result
of the log. Knowing the shape of the graph of the general log function
allows you to perform transformations on it such as vertical and horizontal
shifts, shrinks and stretches a


Logarithmic UISlider 
by NesuD in Development Tools & Services 

Are there any preferred methods for having a UISliders values change
logarithmically, rather than linearly? So that, for example, the value
changes from 0 to 25 over the first half of the slider, and 25 to 100 over
the second half.

How to Calculate Logarithmic Mean 
by The Merg in Hobbies, Games & Toys 

Almost everyone is familiar with the mathematical concept of a mean, even
if they know it by its more common name, the average. By summing the terms
in a series and dividing the resulting number, you can obtain the mean of a
given group of numbers. A logarithmic mean is very much like this. Often
used when calculating temperature differences, a logarithmic mean is
obtained in much the same way as

Logarithmic series of numbers from 1 to MAX 
by Platinumjsi in Programming Languages 

I'd like to calculate a logarithmic range of numbers from 1 to MAX, with
the approximate total count of numbers being TOTAL. A
nonlogarithmic example might be: $max = 3600; $total =
100; $range = array(); for($i = $total; $i > 0; $i){
$range[] = round($max/$i); }
This creates a
roughly equally distributed range ho

Logarithmic plotting of points 
by iyogee in Development Tools & Services 

I was wondering if give a number of 2D points, how do calculate where to
draw a point on a screen in a logarithmic y scale? I tried to
just take the logarithm of all the yvalues of points and than plot them
'normally' (plot point [x, log(y)] => on height: height*log(y)/log(max)).
But this approach causes problems for yvalues under 1. So this makes me
wonder if my method in general

Logarithmic condition of AVL Tree 
by pansapiens in Programming Languages 

For my AVL Tree implementation, I have a node which has a left, right
and parent pointer, and a balance variable. Each time I am inserting a new
node and carrying out the required rotation, I am updating the balance by
subtracting the right subtree from the left subtree. This method in
question calls itself recursively to calculate the height. The
method in question:

How to prove logarithmic complexity 
by Stringjam in Programming Languages 

for (int i = 1; i < N; i *= 2) { ... }
Things
like that are the signatures of logarithmic complexity. But how
get log(N)? Could you give mathematical evidence?

Bigoh complexity for logarithmic algorithms 
by rubyonrails in Careers & Job Searching 

Few more problems I ran into calculating the Bigoh complexity. There
are 2 problems which I cannot solve due to log base operations. Here are
the two problems: n = # of data items being manipulated 1) n^3 + n^2 log (base 2) n + n^3 log (base 2) n 2) 2n^3 +
1000n^2 + log (base 4) n + 300000n I am confused when the logs
have a base number. How do

Logarithmic charts in crossfilter 
by Raghu in Web Design 

I'm charting various lists of data into histograms using crossfilter.
Some of the item's values are a lot higher than others and I'm keen to plot
the histograms in a logarithmic fashion. Is there a way I could
convert all the summed item counts into logarithmic values after reduceSum
has been called? I'm keen to add in something like Math.log(d.count) / Math.LN10;

Logarithmic Bar Chart with Protovis 
by Enar in Web Design 

Can you please help me? I'm trying to convert a bar chart that I created
in linear scale to a logarithmic scale  thus, the y axis needs to be
logarithmic. The x axis is just the years, so it can be linear. But I'm
having so much trouble understanding how the scales work, even with the
tutorials. var w, h, allData; w = 1000, h =
600 allData = [220,240,240,260,300,
