Detailed File Size Spread

 
Detail Menu
The File Size Spread display is a more powerful version of the magnitude display.
(a) Build the graph
(b) Select the resolution of the graph. Small numbers make for more detailed graphs but at the expense of build time and memory usage. The default is 512K so they first bar of the graph will show the number of files between 0 bytes up to (but not including) 512k, the second bar for files of 512k up to (1MB and so on in intervals of 512K.
(c) Build the graph from only a selected range of file sizes form (d) to (e) inclusive.
(d) Start size for the range.
(e) End size for the range.
(f) Use a multi-coloured graph or colour based on y-axis value (darker colour for larger values).
(g) Use a logarithmic Y-axis.
 
 
 
 
 
 

In the example below the "multi" colour mode is shown. There is too much information to show on the X-axis so the information is available by moving the mouse over a bar. The mouse is located over "blue" bar next the end, the top part of the example shows that this bar represents files of 3.50MB up to (but not including) 4.00MB of which there are 24.

The interval in this example is 0.5MB or 512KB. Each bar represents a spread of this amount.
In the example below the "gradient" colour mode is shown. The mouse is located over the bar that represents files of 15MB up to (but not including) 16MB of which there are 3.
 
Benford's Law
Benford's Law describes how the distribution of a set of numbers should vary with the leading digit of each number.
Numbers beginning with '1' should be around 30.1%, '2' 17.61%, '3' 12.49%, '4' 9.69%, '5' 7.92%, '6' 6.69%, '7' 5.80%, '8' 5.12% and those beginning with '9' would only be expected to account for 4.58% of the total.
The Benford's Law display will show you the distribution of the file sizes according to the file size's leading digit.
