</td></tr></table> <p><div style="font-weight:bold;font-family:arial;font-size:100%;">Class usage and Overview</div>This class is used to creat line graph plots. Line graph plots are used to draw standard lineplots where datapoints are connected by lines. Each data point can also be marked by a plotmark.
|
|
<p>
|
|
A line plot can only be added to a Graph() image.
