ds
'ds' <1.Dataset-Nr> [<2.Dataset-Nr>] [<n.Dataset-Nr>] 'a[h]'|'e[h]' ->
[<entity-nr> (up to 4 times)]|
['o' <value> [<entity-nr>]]|
['s' <value>]
This keyword is used to define one or more Datasets and one or more Entity for display purposes. The Dataset has to be a positive number which has to match the nr in the Dataset-menu or an 'l' (lower case 'L') which is interpreted as the last available Dataset or a negative number. Then it is interpreted as the last ds minus the specified number. For example
ds 1 e 1
will display the first entity of the first Dataset.
ds l e 1
will display the last Dataset.
To start the animation of the second-to-last Dataset right away:
ds -1 a
Or generate an animated fringe plot by adding the desired entity:
ds -1 a 4
Sequences can be defined by specifying one to three datasets and by extending the 'e' parameter by an 'h' ('history'):
ds 2 eh 1
Here all datasets of the same type as ds 2 are selected. The spacing between datasets of the same type is only evaluated for the first step. A unique step-with is therfore needed.
ds 2 10 eh 1
Here the datasets 2, 10 and all successive ones of the same type with a spacing of 8 are selected.
ds 2 4 10 eh 1
Here the 1st entity of each second Dataset is selected. The selection starts at the second- and ends at the 10th dataset. If more than one entity is defined then a vector-plot will be displayed. If a 4th entity is defined then this entity will be used for the basic color-plot:
ds 2 4 10 eh 12 13 14 15
In case the deformed shape should be shown together with the fringe plot in a sequence of datasets then the 'e' parameter has to be replaced by an 'a' character.
ds 2 ah 1
REMARK: So far vector plots can not use the deformed shape. Therefore only one entity is supported.
In addition, it is possible to scale or offset the entities of the specified datasets:
ds 1 s 1.2
will scale all entities of dataset 1 by a factor of 1.2.
ds 1 o 200.
will add a value of 200 to all entities of dataset 1.
ds 1 o 200. 2
will add a value of 200 to the entity 2 of dataset 1.
