Animation through Sequence
The user can generate graph animation using a data sequence or graph
sequence. There are two closely
related but subtly different ways of creating graph animation using a data
sequence or graph sequence. We will
discuss them the following two sections.
Animation Using a Data Sequence
When a data sequence is selected as
the active document, the Data Sequence tool
on the ToolBox can be used to open the Data
Sequence dialog box with which the
user can play back all data tables in the data sequence: each data table will be
made the current data table of the data sequence sequentially for a specific amount of time.
After changing the current data table of the
data sequence, DataScene automatically refreshes the dependent graphs -
graphs
that use the data sequence as their data source - with the data in the current
data table of the data sequence. As a result, the user will see that all dependent
graphs of the data sequence keep plotting data in each of the data tables of the data sequence and
a graph animation is thus created.
Animation Using a Graph Sequence
When a graph sequence is selected as
the active document, the Graph Sequence tool
on the ToolBox can be used to open the Graph
Sequence dialog box with which the
user can create graph animation. Animation
through graph sequence works in the following way: when the user clicks the Start/Resume
button on the Graph Sequence
dialog box, DataScene automatically finds out all data sequences that are used as
the data
sources of the active graph. For each of these source data
sequences, DataScene changes the current data table sequentially in it and
refreshes all its dependent graph sequences. After having updated the current
data tables of all the
source data sequences and refreshed their dependent graphs, DataScene pauses for a specific time interval and then starts the
whole process again. It is obvious that any graph sequence document (including
the active graph sequence) that depends on one of the source
data sequences will be animated in this process.
