[reportlab-users] Computing chart size

Thanks, I like the result it produces. I've some questions, however:

1. Since the width is fixed, if I put more data, the data points are placed 
more closely. Is it possible to specify the spacing between data points, and 
compute the needed width of the image.

2. You use LineLegend, but my copy of sources have only "Legend". Is 
LineLegend a recent addition?

3. Where is 'makeMarker' defined?

Thanks,
Volodya
