-====== Datasets and Plots inside GroIMP ======
+====== Plots inside GroIMP ======
+GroIMP has the ability to visualize datasets in different plots.
-GroIMP comes with an included management of dataset and the ability to visualize them, in the following only a small introduction is given.
-===== Datasets in RGG =====
+===== =====
+To learn more about datasets visit the [[02_user_tutorials:dataset:01_basics
+|dataset tutorial]].
-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>
-DatasetRef diagram = new DatasetRef("plot");
-</code>
-In a dataset each row is described as a Dataseries and to add data a new series has to be added as following:
-<code java>
-Dataseries ds = diagram.addRow();
-</code>
-Now we can add numeric data to the different columns of this series by using the set function:
-<code java>
-ds.set(0,1.54);
-ds.set(1,3);
-for(int i=2; i<10; i++){
- ds.set(i,i+i);
-}
-</code>
-It is also possible to create a new row in a dataset in one line of 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:
