The following curve functions require a graph address that specifies
where to place the newly created curve on the graph..
Since the curve functions automatically create new graph tabs, grids,
and axes, a testplan can have multiple functions that generate curves
and the order of the testplan rows does not matter.
All of these curve functions require three arguments that define the
graph address:
- The graph_name argument specifies
the name of the tab on which the curve appears.
- The grid_index argument defines
the order in which the curves appear on the graph. The value of grid_index is an alphanumeric string starting
with the letter A, such as A1, A2, A3 etc. Analog grids are assigned
grid indexes starting at A1,which is both the default and the bottom-most
grid. The numeric indexes increase as additional grids are added to
the graph.
- The axis name argument specifies
the name of an axis on the same grid index. Currently, this is used
for only the default grid where the grid index is A1. Multiple axes
can be added to the default grid index (A1), but the additional grids
(A2, A3, etc) can have only a single axis. Currently, DVM supports
up to 100 grids per graph tab.
Graphs created with these curve functions can also be placed on graphs
generated from fixed probes or from other curve functions.
Important:
The
graph address along with the curve name must specify a unique item on
the graph - that is, a single curve. Errors result if you duplicate curve
names on the same graph sheet or if you specify addresses that conflict.
For example, if you already have an axis with a specified name on grid
index A2, you will get an error if you specify a new axis with a different
name on that same grid index A2.
