[Qgis-user] How to create a gradient from parallelograms

Hi there,
I have a massive problem and I am desperately in need of help.
Beforehand:
my operative system is windows 7.
I have qgis 2.8.1 - wien
I installed it with a standalone-installer.
Now my problem is:
i have a vector layer of points that represent gps locations of dolphins in
the estuary.
I have a mathematical formula to calculate the area of error associated to
the location of each point. This formula generates the area of
parallelograms and so for each point I have the area of the associated
parallelogram (each point is the center of its associated parallelogram).
Some of these parallelograms will overlap each other and I will have a
bigger error associated to the location of points in those areas.
So far I have the area values of the parallelograms and the coordinates
(x,y) of their centers.
I need to create a gradient (imagine a density gradient) but for the
overlapping parallelograms. This is my final goal!
But I don't know how to do this! I don't even know how to draw the
parallelograms.
Thank you so much!
