Helo,
I have a question about the structure of an XML file to build a Gantt chart.

I use an XML file containing:
<booking>
<reserves startDate="24/8/2011" endDate="9/8/2011" id="1">
    <owns name="Titi" address="Street one"/>
    <concerns>
    	<area>B</area>
    	<capability>4</capability>
    	<name>Red house</name>
    	<roomCount>2</roomCount>
    </concerns>
    
  </reserves>
  <reserves startDate="21/9/2011" endDate="28/9/2011" id="2">
    <owns name="Toto" address="Street two"/>
     <concerns>
    	<area>A</area>
    	<capability>4</capability>
    	<name>Blue house</name>
    	<roomCount>5</roomCount>
    </concerns>
  </reserves>
  <reserves startDate="10/9/2011" endDate="11/9/2011" id="3">
    <owns name="Tutu" address="Street three"/>
     <concerns>
    	<area>A</area>
    	<capability>4</capability>
    	<name>Blue house</name>
    	<roomCount>5</roomCount>
    </concerns>
  </reserves>
</booking>


I would like to create a gantt chart with date in x-axis and area (A,B) in Y-axis.

In the "edit dataset" window in Birt, what Row mapping must I choose ?
/booking/reserves/concerns ?
/booking/reserves/concerns/area ?
/booking/reserves ?

Whatever path, I always have 2 rows for A area and 1 row for B area in the preview result in the Edit dataset window and in my gantt chart I have 2 A and 1 B in y-axis.

I would like to group booking by area in order to have 1 phase for Toto and one phase for Tutu for the A area. Is it possible or must I change the XML file structure ?

Thanks in advance.

Val

Val,

What do you want to do with the area b? I am not sure what you want the
resultant chart to look like.

Hello Jason,

Thanks for our reply.
I would like to create a gantt chart to display each booking for each area.
So in the x-axis, there will be placed dates, and in the y-axis, I would like to have area.
Each task represents a reservation( from startdate to enddate).

See the attachment:

index.php/fa/4077/0/

In this image, I only have one task (booking) for each area.

Changing Toto and Tutu start and end dates (on A area), I realised that Tutu booking and Toto booking using A area are glued. The chart considers that the task is from Tutu booking startdate to Toto booking enddate. Why ?

I attach the rptdesign and xml data files too, that create this gantt chart.

Thanks in advance.

Val.

I found the solution Very Happy :

I create a Data Cube with 2 groups (areaGroup based on area field and ownerGroup based on area field), and I added startDate, enddate and OwnerName in summary fields.

Then, in the gantt chart, I use this data cube. I placed startDate and endDate in the value Y series, and areaGroup in Category x Serie. I filled the Optionnal Y serie grouping with the second group ownerGroup.

That's OK.

This can help someone else !

Thanks Jason.

Val,

Take a look at the attached example that uses your data. Notice I added
two computed columns for the dates.
