Defines the number of levels to display in the time scale of a chart as well as the maximum level.
Note: This function can be used in conjunction with <Chart>.TimeLevelMask to define a mask for one level of the graph's time scale..
Example
// The maximum number ol fevels to display is set to 2
CHART_MyChart.TimeLevelMax(2)

// Forbids the display of years for CHART_MyChart
CHART_MyChart.TimeLevelMax(3, grtlMonth)
// Définition de l'échelle temporelle pour afficher plusieurs valeur par mois
// mais en affichant uniquement les mois dans l'échelle 
// (les jours ne sont pas affichés)
GRF_MonGraphe.NiveauTemporelMasque(grtlMonth, "Mmm")
GRF_MonGraphe.NiveauTemporelMax(1, grtlMonth)
Syntax
<Chart control>.TimeLevelMax(<Number of levels> [, <Maximum level>])
<Chart control>: Control name
Name of the Chart control to use (in the window or page editor).
<Number of levels>: Integer
Maximum number of levels displayed in the chart.
<Maximum level>: Optional Integer constant
Maximum level to display:
grtlDayMaximum level displayed: days.
grtlHourMaximum level displayed: hours.
grtlMillisecondMaximum level displayed: milliseconds.
grtlMinuteMaximum level displayed: minutes.
grtlMonthMaximum level displayed: months.
grtlSecondMaximum level displayed: seconds.
grtlYearMaximum level displayed: years.
Remarks
When displaying a time scale on DateTime data, the chart designer draws several levels corresponding to the different time units displayed.
  • The minimum level to display is defined according to the range of data.
  • The maximum level is defined by using two parameters:
    • Maximum number of levels to be displayed in the graph (default: 3).
    • The maximum level allowed for display (default: year).
<Chart>.TimeLevelMax is used to modify these parameters. This allows you not to overload the chart or not to display some levels without relevance for the data displayed.
For example:
  • to avoid displaying the years, all you have to do is set the maximum level with the grtlMonth constant.
  • to avoid displaying more than two time levels in the chart, all you have to do is set the <Number of Levels> parameter to 2.
