Next: Area Series, Up: Object Groups [Contents][Index]
All of the group objects contain data source parameters. There are
string parameters that contain an expression that is evaluated to update
the relevant data property of the group when the refreshdata
function is called.
Evaluate any ‘datasource’ properties of the current figure and update the plot if the corresponding data has changed.
If the first argument h is a list of graphic handles, then operate
on these objects rather than the current figure returned by gcf
.
The optional second argument workspace can take the following values:
"base"
Evaluate the datasource properties in the base workspace. (default).
"caller"
Evaluate the datasource properties in the workspace of the function
that called refreshdata
.
An example of the use of refreshdata
is:
x = 0:0.1:10; y = sin (x); plot (x, y, "ydatasource", "y"); for i = 1 : 100 pause (0.1); y = sin (x + 0.1*i); refreshdata (); endfor
