Re: Next higher number for graph scale

[Antonio Fernandez-Vicenti <afvaiv@xxxxxxxxxxxxxx>]

Not sure if I understood you right, but here is my 2 cents contribution.
Let's assume the highest value was 17134
Your first scale value should be 3500, isn't it?
Calcs:
Divide highest value 17134 by 25 , which gives 685.36
Round this figure to the next round  number with just ONE single digit 
plus several zeros, i.e. 700
Multiply that number by 5, giving out 3500 which is your first scale value.

Another case, asume highest value is 73445. First scale should be 15000, 
isn't it?
Divide 73445/25 = 2937.8  rounded up to 3000
Multiply 3000 * 5 = 15000

HTH, and regards
Antonio
