Sets the reference tick.

<p>
|

|
The reference tick is a date/time which specifies a tick which should always be displayed on the axis. This is needed when the tick interval multiplier is not 1 (e.g. the interval between two ticks is 3 months). In that specific case, there is no way for the control to know which ticks should be displayed (in our example, the chart doesn't know if the first tick will be january, february or march). This is particularly annoying when the axis is panned (in that case, if we always take the first month on the axis as first tick, the ticks will always switch from one month to another). By having a refence tick, this forces the control to calculate all tick intervals based on this reference. It is set to January 1st 2000 by default.

Sets the tick increment.

<p>
|
||
|
|
The tick increment is the value between two adjacents ticks on the axis. In case of a date time axis, the interval is specified by a time period because this interval might not be constant (for instance, if a tick interval of one month is specified, the distance between two adjacents ticks is not constant: it depends on the number of days in the month). The full tick interval is made of a base interval (day, month, hour, ...) and a multiplier, that is applied to this base interval. So, for an interval of three months between two ticks, you have to specify tiMonth for the interval and 3 for the multiplier. <dl compact><dt><b>Parameters:</b></dt><dd>
