Change a shape of points of XYPlot series
<p>I want to set a shape of points as a circle. This is how I do it:</p>

<pre><code>Shape shape  = new Ellipse2D.Double(-5,-5,5,5);
renderer.setSeriesShape(0,  shape);
</code></pre>

<p>Then I get the following result:</p>

<p><a href="https://i.stack.imgur.com/NLtoY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NLtoY.png" alt="enter image description here"></a></p>

<p>Circles are slightly shifted. I tried to change <code>(-5,-5,5,5)</code> in order to center circles according to the line, but nothing has worked. What is the right way to center the circles? </p>
