Baseline is always zero #23
Description
It'd be nice if you could set any values to the trendline, let's say 5,3,3,5,6,10 and the baseline would be 3 in this case, instead of 0.
And also, if you set the last value to 10, it'll try to draw down to zero, making the chart look weird.
Another interesting feature would be to define a "fill" color to the shape which forms.
