Screenshot showing the graph with incomplete plotting.
SUMMARY
I was following a basic tutorial on how to use LabPlot2, and I noticed an
apparent error when trying to plot graphs for polar equations. The YouTube
tutorial link is below, and the actual error occurs between 2:20 and 2:45 of
the video:

I tried creating an equation with different values, opening a new graph area,
and the problem seems to be with the polar plotting function.
STEPS TO REPRODUCE
1. Open LabPlot2
2. In the open default project, add a new worksheet
3. In the new worksheet, add two axes (any)
4. In the new graph area, add a formula plot
5. Change the equation type to polar
6. Enter any equation or constant in the formula editor and press "Recalculate"
7. Here's the error. Instead of a complete polar graph, the plot displays only
a small fragment of a line.
OBSERVED RESULT
The plot displays only a small fragment of a line.
EXPECTED RESULT
The graph shows the complete line.
