Don't miss the gnumeric manual, there's a lot of useful informations in
it...

One of the main usability issue with the chart guru is the "Add" menu is
populated only with list of objects that can be added to the selected
item. For example, if you want to add horizontal grid lines, you need to
select the y axis, then click on the "Add" menu and select "Major grid
lines".

The situation could be improved by populating the "Add" menu with all
objects that can be added to the graph (or may be a selection of the
most used objects + the list of possible selected object childs), and
popup a selection dialog if there's more than one possible parent.

We could also add a palette of the most used objects (Title, Axis,
Legend...).

It's a "line" chart, without what's called Grid object (and is in fact
chart backplane, we should rename this one), and with grid lines which
are childs of x and y axes.
