vertical axis scale not corresponding to plotted values

What steps will reproduce the problem?
1. Make a graph with 3 vertical axes and 3 series:

2. use a big data array, minimum about 3000 values per serie

3. One serie must be in the range of .9 to 1 and the vAxis for that serie must 
be minValue=0 and maxValue = 1

What is the expected output? What do you see instead?
The expected output is the .9 to 1 serie to show in a range from 0 to 1
Instead it shows the values in the min-max value range of the data, meanwhile 
the vertical scale shows correctly the desired range (0 to 1)

What version of the product are you using? On what operating system?
google.load('visualization', '1.1', {packages: ['corechart', 'controls']});

in every OS, Mac, Windows, Linux-Ubuntu
tested in Firefox and Chrome

Please provide any additional information below.
The provided values are ten days of data in my application, I think this 
happens when the variation in the data is not greater than .3 if there is a 
variation greater than .3 the values appear correctly in the 0 -1 range

I'm attaching an example of this, please note the red serie, the values plotted 
and the scale
