Bar Chart

Hello BIRT community,<br />
<br />
I am using BIRT 2.6.2.<br />
For example: I have dataset with 2 colums. one are names the second are values.<br />
And I wanted to created a bar chart which looks like:<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>name 1

---

name 2

---

name 3

---

0 10 20 30 40 50</pre>
<br />
I have bound the row[name] to the x-series and the row[value] to the y-series. Do I have a logic error because I onyl get the half of the dataset and sorted in very strange way?<br />
<br />
For any hints and suggestions thanks in advance.
