<Chart>.TimeLevelMax (Function) In french: <Graphe>.NiveauTemporelMax Defines the number of levels to display in the time scale of a chart as well as the maximum level. Remark: This function can be used with <Chart>.TimeLevelMask, which defines the mask of a level in the time scale of the chart. // The maximum number ol fevels to display is set to 2 CHART_MyChart.TimeLevelMax(2) Â // Forbids the display of years for CHART_MyChart CHART_MyChart.TimeLevelMax(3, grtlMonth)
// Set the time scale to display several values per month // but displaying only the months in the scale // (days are not displayed) CHART_MyChart.TimeLevelMask(grtlMonth, "Mmm") CHART_MyChart.TimeLevelMax(1, grtlMonth)
Syntax
<Chart control>.TimeLevelMax(<Number of levels> [, <Maximum level>])
<Chart control>: Control name Name of the Chart control to use (found in the window editor or the page editor). <Number of levels>: Integer Maximum number of levels displayed in the chart. <Maximum level>: Optional Integer constant Maximum level to display: | | grtlDay | Maximum level displayed: days. | grtlHour | Maximum level displayed: hours. | grtlMillisecond | Maximum level displayed: milliseconds. | grtlMinute | Maximum level displayed: minutes. | grtlMonth | Maximum level displayed: months. | grtlSecond | Maximum level displayed: seconds. | grtlYear | Maximum 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:
- The maximum number of levels to display in the chart (by default: 3).
- The maximum level allowed for the display (by 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.
