Remarks

Details

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 (3 by default).
    • The maximum level allowed for the display (by default: year).
grTimeLevelMax 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 grntMonth 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.
