I wrote the code to generate this attached Bar Chart, though I cannot seem to find the functions I need to address a client's needs.

All the values range from 0 to 100, but the bar chart always scales like a window from 0 to the Largest value, Is there a way to make it show 0 to 100, regardless of the array of values passed in?

Also as a second request, This is a T-Score value that is calculated.  The Normal range for an individual is 60 to 80.  Is there a way to color those horizontal area's between the 60th and 80th values?

Hi Craig,

You may use Axis.setLinearScale to configure the axis scale. For example, in PHP, it is like:

#set the scale from 0 to 100 regardless of what are the data
$c->yAxis->setLinearScale(0, 100, 10);

You may use Axis.addZone to add a zone between 60 to 80. For example:

#Add a light red zone (0xffcccc) between y = 60 and y = 80
$c->yAxis->addZone(60, 80, 0xffcccc);

Hope this can help.
