this behavior comes from the fact that you did not provide the correct y-axis id and x-axis id in the boxes definition.

i see that you did not put any id for x-axis and y-axis in your chart's xaxes and yaxes definition, so their default ids are 'x-axis-0' and 'y-axis-0'.

for each of your boxes definition, try changing

'xscaleid' : 'xaxes',
'yscaleid' : 'yaxes' 

into

'xscaleid' : 'x-axis-0',
'yscaleid' : 'y-axis-0'
