<p>Hi,</p>
<p> </p>
<p>I have a Stacked bar chart with 2 Y axis, they are sort by the X axis, and i need to <span>distinguish the data of the first Y axis but not for the second axis.</span></p>
<p> </p>
<p><span>I had the column i need to <span>distinguish in the SQL request and group by this column. The other data are sums.</span></span></p>
<p> </p>
<p><span><span>How can i only <span>distinguish the first Axe but not the second one.</span></span></span></p>
<p> </p>
<p>I'm on Birt 3.2.17 and using eclipse for Birt.</p>
