Steps to change the Gantt diagram from GeneXus to show your data:

1. Give permissions to the Gantt folder by right-clicking on it and selecting Properties, Security tab, Control
2. Design a procedure that changes the XML file
3. To change the file use only 3 GeneXus functions:

&xml.Open(trim("Gannt\Gantt.xml")) // to open and delete the xml
&xml.WriteRawText("..........") // to add 1 line of text in the xml
&xml.Close() // to close the xml file
&xml is a variable DataType XMLWriter

4. Important... you should enter the data in the structure already defined by the file.
