NtTimeChartControl.GetNtPerspective Method
Within the NtTimeChartControl the current row order and category settings are defined by a NtPerspective object.
This object simply defines a set of categories and subcategories and which data types are shown in which category and within. In other words: Once an application defined how certain data types
shall be displayed in terms of colors, fonts, curves, texts etc. the NtPerspective defines the final order on the screen.
The reason for this approach is that certain data is always displayed in the same way (for example a medical chart might always display the heart rate in a red curve). Still the user may then be free to show or hide
certain data or prefers a certain arrangement of different curves and values on the chart. For this reason, the active NtPerspective can quickly be exchanged. This means
that you might have certain standard perspectives and then quickly swap the display between them.
Example: Same data, differend row order arranged by two different perspectives:
