    <p>I have a small problem with ploting my graph. On a picture below is what I have already done.</p> <hr> <p>The graph should represent the actual signal strength of available Wi-Fi network(s). It's a simple <code>XYPlot</code> here data are represented with <code>SimpleXYSeries</code> (values are dynamically created).</p> <p>Here is a little snippet of code (only for example):</p> <pre><code>plot = (XYPlot) findViewById(R.id.simplexyPlot); series1 = new SimpleXYSeries(Arrays.asList(series1Numbers), SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Link 1"); f1 = new LineAndPointFormatter(color.getColor(), null, Color.argb(60, color.getRed(), color.getGreen(), color.getBlue()), null); plot.addSeries(series1, f1); </code></pre> <p>The example in the picture is a dynamic simulation of dB changes. Everything works, I guess, correctly, but what I want to achieve is to have line with "rounded" corners (see the picture to see what I mean).</p> <p>I already tried to customize LineFormatter:</p> <pre><code>f1.getFillPaint().setStrokeJoin(Join.ROUND); f1.getFillPaint().setStrokeWidth(8); </code></pre> <p>But this didn't work as expected.</p> <p><img src="https://i.stack.imgur.com/VyH4R.png" alt="Enter image description here"></p> <p>Note: The <a href="https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer" rel="nofollow noreferrer">Wifi Analyzer</a> application has a similar graph and its graph has the rounded corners I want. It looks like this:</p> <p><img src="https://i.stack.imgur.com/jILfk.png" alt="Enter image description here"></p>

    1. COYou might find this post helpful, http://stackoverflow.com/a/7608516/2291915. getFillPaint() returns android's Paint object and from there you can use the Android methods to achieve the effect you desire. Best of luck.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
