Hi,
I think that in Logarithmic Scale documentation http://www.chartjs.org/docs/#scales-logarithmic-scale, Example Configuration is missing 'scales' in 'options'.
options: { xAxes: [{ type: 'logarithmic', position: 'bottom', ticks: { min: 1, max: 1000 } }] }
should be:
options: { scales: { xAxes: [{ type: 'logarithmic', position: 'bottom', ticks: { min: 1, max: 1000 } }] } }
