How to Control number of minorticks between two ticks of axis ?

Question

Hi Guys,
I want draw number of minor ticks between two ticks of vertical axis of column chart based on user input.
ex:if user is providing 2 there should be two minor ticks between two ticks of axis.
Thanks in advance.

Answer 1

From what I can tell with fooling around with it, the minorInterval value divides the vertical count to give the appropriate number of ticks between each interval.
<mx:LinearAxis id="countAxis" alignLabelsToInterval="true"
      autoAdjust="true" minorInterval="2"
      minimum="0" interval="10"
      maximum="100">
</mx:LinearAxis>
In the example above, I have the interval at 10 and when I set the minorInterval to 2, then I get 5 ticks.  The first tick is at the interval and then followed by 4 more ticks.
In your example, in order for me to see 2 ticks between the intervals, then I would have to set the minorInterval to 3.5 .
10 / 3.5 = 3 (2 ticks)
The forumla would have to be something like:
ViewableTicks = Interval / (Selected Ticks + 1);
So, if I created a droplist, with 1 - 9 ticks (because 0 doesn't work if you are showing minor ticks), then when the option is changed, I would calculate the value for the minor ticks and set the LinearAxis component (countAxis) to that new value.
protected function tickViewList_changeHandler(event:IndexChangeEvent):void
var tickCount:int = tickViewList.selectedItem;
var tickView:Number = countAxis.interval / (tickCount + 1);
countAxis.minorInterval = tickView;
I created a blog post showing my example.
