<p>Hello,</p>
<p>I have a question regarding gantt charts but first of all i'm gonna explain my data set:</p>
<p> </p>
<p>The dataset is about different machines with production and loss time.</p>
<p> </p>
<p>For example my rows for one machine in my dataset:</p>
<p> </p>
<p> </p>
<p>MID Production_Start Production_End Loss_Start Loss_end </p>
<p>638 02.03.2013 06:00:00 02.03.2013 06:01:06 <br>
638 02.03.2013 06:07:58 02.03.2013 06:42:49<br>
638 02.03.2013 10:17:59 02.03.2013 10:49:10<br>
638 02.03.2013 06:01:06 02.03.2013 14:00:00 <br>
638 02.03.2013 14:00:00 02.03.2013 14:01:05 <br>
638 02.03.2013 14:01:05 02.03.2013 22:00:00 <br>
638 02.03.2013 22:00:00 02.03.2013 22:01:06 <br>
638 02.03.2013 22:01:06 03.03.2013 06:00:00</p>
<p> </p>
<p>I created 2 data sets, one for production and one for losses and they are grouped by the machine id.</p>
<p>So here is my problem: As aggregation function i can only choose between min/max or first/last for the date values and as soon as i pick one of them Birt puts everything together to one big bar.</p>
<p>Is there an option to display everything in the same "row" but keep every entry seperated?</p>
<p>It's important because i need seperated tooltips for every part.</p>
<p> </p>
<p>I've attached a screenshot where you can see how every single row (bottom chart) looks like after grouping them (top chart)</p>
<p>I hope you understand my issue and help me.</p>
<p> </p>
