Hi Susanne,
I believe you need to set "point to fill" to one of x1, x2, y1, y2,
depending on where your graph touches the plot axes.

<br>
we would like to create the graph of inequations like y < 2x + 1.<br>
The relations 'less or equal','greater than', 'greater or equal' should<br>
also be possible.<br>
We try to get the correct graph by using 'filledcurves' as typ of the<br>
plot. As a result the area on the right of the straight line is marked,<br>
no matter if we choose 'above' or 'below' for the parameter 'points to<br>
fill'.<br>
Moreover, sometimes no area is marked: This concerns simple straight<br>
lines like y=0.8*x*3.<br>
<br>
How do we have to set which parameters to mark the area on the left or<br>
an the right of the straight line?<br>
