 GroIMP comes with an included management of dataset and the ability to visualize them, in the following only a small introduction is given.
-===== Datasets =====
+===== Datasets in RGG =====
 A datasets in GroIMP are simple tables, that can be referenced from RGG and the GUI.
+==== Getting data in ====
 To create a Dataset in GroIMP the DataSetRef object is used as following:
 <code java>
@@ Line 27: / Line 30: @@
 </code>
-Alternative
+It is also possible to create a new row in a dataset in one line of code:
-<code>
+<code java>
 diagram.addRow().set(0,1).set(1,2);
 </code>
+==== Clearing ====
+A dataset is a Resource of GroIMP and therefore not removed when the simulation is reset or recompiled. In order to clear a dataset the following command can be used.
+<code java>
+diagram.clear();
+</code>
+==== Column titles ====
+Similar to the set function it is possible to add column titles using the following command:
+<code java >
+diagram.setColumnKey(0,"max(x)").setColumnKey(1,"max(y)").setColumnKey(2,"max(z)");
+</code>
+==== Exporting datasets ====
+It is possible to export a dataset from RGG using a Java FileWriter as shown below:
+<code java>
+import java.io.FileWriter;
+public void getData(){
+	DatasetRef diagram = new DatasetRef("plot");
+	FileWriter fw = new FileWriter("/home/tim/test.csv");
+	diagram.export(fw);
+	fw.close();
+}
+</code>
+It is also possible to define the Separator that is used for the file by e.g. ''diagram.export(fw,",");''
+And the same works as well  with a StringBuffer instead of the FileWriter.
+===== Datasets in Gui =====
+The datasets can be seen in the dataset explorer. This can be found in the main menu under Panels/Explorers/datasets. Clicking on a dataset opens a very simplistic table view where the data can be seen and also exported.
+===== Visualizing Datasets =====
+To visualize a dataset in GroIMP the chart() function is used:
+<code java>
+ chart(diagram, XY_PLOT);
+</code>
+in a full example like this:
+<code java>
+module A(float len) extends Sphere(0.1)
+{
+	{setShader(GREEN);}
+}
+DatasetRef diagram = new DatasetRef("plot");
+protected void init ()
+[
+	Axiom ==> A(1);
+	{
+	diagram.setTitle("My fancy plot");
+	 diagram.clear();
+     diagram.setColumnKey(0,"max(x)").setColumnKey(1,"max(y)").setColumnKey(2,"max(z)");
+	 chart(diagram, XY_PLOT);
+	}
+]
+public void run ()
+[
+	A(x) ==> F(x) [RU(30) RH(90) A(x*0.8)] [RU(-30) RH(90) A(x*0.8)];
+	{
+		diagram.addRow().set(0,max(location((*A*)).x)).set(1,max(location((*A*)).y)).set(2,max(location((*A*)).z));
+	}
+]
