Feature request - start plotting graph from x-axis zero point

[bongobongo]

I have set Ymin to 20,00 and Ymax to 200,00.
Then: Xmin to 0,00 and Xmax to 250,00
When data comes in, it start plotting at the right edge of the plotting area and then the plot
scrolls left.
Is it possible to tell serialPlot to start plotting at x=0,
and only if the number of datapoints is not within Xmax, then start scrolling the plot horizontally to see rest of the incoming data.

If that is not possible it would be cool if you could add this feature.
