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 (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.
