First data series on chart does not scale

anmatr

<p>Hello,</p>
<p>As I use a LineSeries Chart with BIRT 4.2.2 in an eclipse RCP application entirely done from BIRT API I face the following issue:</p>
<p> </p>
<p>The attached picture shows two graphs which both are done from the same data. It is that BIRT renders the first series on a scale from 0 to 0,8 and the second data series on a scale from 0,694 to 0,746. </p>
<p>As I want already the first one scaled from 0,694 to 0,746 I don't know how to achieve this. </p>
<p>I remember somewhere I read that BIRT would automatically scale and it does so on the first data set, not on the second one.</p>
<p> </p>
<p>I played around with the methods:</p>
<p> </p>
<p>setScale().setMin</p>
<p>setScale() .setStep()</p>
<p>setScale() .setAutoExpand(true)</p>
<p> </p>
<p>but no effects towards my needs. I've attached the code and the picture.</p>
<p> </p>
<p>Hopefully someone finds this of interest and can point me to the right way of doing it.</p>
<p> </p>
<p>Thanks,</p>

<p>All,</p>
<p>   luckily I found the culprit, but I still cannot explain it completely. If anyone has some insight please enlighten me.</p>
<p> </p>
<p>When building the XAxis I used:</p>
<p> </p>
<p>xAxis.getOrigin().setType(IntersectionType.VALUE_LITERAL);</p>
<p> </p>
<p>and the data displayed as described. But with</p>
<p> </p>
<p>xAxis.getOrigin().setType(IntersectionType.MIN_LITERAL);</p>
<div> </div>
<div>all looks good now and the graph scales properly.</div>
<div> </div>
<div> </div>
<div>Would be great if anyone could explain why that is. Especially as I have another graph where I use the VALUE_LITERAL and all looks good. So there must be another setting which has an impact on it.</div>
<div> </div>
<div>Thank you,</div>
