87        This page shows the various options for in-graph labels. The in-graph labels can be set like this:
88    </p>
89   
90    <pre class="code">obj.Set('chart.labels.ingraph', [,,'Hoolio',,'Olga']);</pre>
91   
92    <p>
93        Or like this if you want to be more specific:
94    </p>
95   
96    <pre class="code">obj.Set('chart.labels.ingraph', [,,<span style="color: green">['Hoolio', 'red', 'yellow', -1, 60]</span>,,'Olga']);</pre>
97
98    <p>
99        The array can consist of:
100    </p>
101   
102    <ul>
103        <li>The label text</li>
104        <li>The text color</li>
105        <li>The background color</li>
106        <li>This can be 1 or -1 and denotes whether the label should be above or below the line. This has no effect in Bar or Scatter charts</li>
107        <li>The length of the label pointer/arrow</li>
108    </ul>
