title: Force axis to use given number of major tick marks in Visiblox chart
body: <p>When using a LinearAxis for the Y axis in a Visiblox chart, I would like to force the axis to use a given number of major tick marks while still having the toolkit automatically calculate the axis range and tick mark locations. For instance, I may have a primary and secondary Y axis and I want both axes to use the same number of major ticks so that their horizontal gridlines overlap. Is this possible?</p>
