(2) You define default for the x,y range as [-10, 10]. Shouldn't the default be guessed by the data values ?
Yes, but I'm finding that it's harder than it seems to pull this off right. Picking a range that contains all / a majority of the axis is relatively easy (scale axis to n standard deviations), but making the ticks fall on "nice" numbers is a little harder. This is a goal for this project, but is not my primary one for the time being. Also, the user may want to have good control over the plot window, so I'm not sure just how much guessing the header should do without being told to do so. My philosophy has been to leave the lowest-common-denominator as a default, and this would be something the user would specify my_plot.auto_scale_x(true).y_range(-1, 15);
(3) Instead of x_external_style_on you could use x_axis_alignment( alignment_type alignment ) where alignment is one from {center, top, bottom}, the default case would be alignment==center, while the bottom alignment would produce the same effect of x_external_style_on(true), and the top alignment would put the x axis ticks and values on the top of the window; similiarly for the y axis you could make use of a method y_axis_alignment( alignment_type alignment ) with possible alignment values center, left and right.
That's a great idea! This will also allow me to easily change the alignment of the axes for when the alignment is "center", but the axis is not drawn within the plot window. The solution I've been sketching out in my head was more of a brute-force attack, but it seems this more elegantly solves the problem. Thank you, Jake
