numDivLines attribute does not work or produces unpredictable outcome when yAxisMinValue or yAxisMaxValue is used.
The XML below will return three horizontal lines in stead of two
<graph numDivLines='2' yAxisMinValue='1000'>
<set name='Bar 1' value='22413' color='639aff' />
<set name='Bar 2' value='5082' color='ffcf00' />
<set name='Bar 3' value='25462' olor='ff6500' />
<set name='Bar 4' value='8009' color='9ccf63' />
<set name='Bar 5' value='25871' color='bd86de' />
</graph>
