Patrick Durusau commented on OFFICE-3928:
-----------------------------------------

I was trying to apply this resolution but have some wording questions:

For the new element: <chart:coordinate-region>

Proposal reads:

"The attributes of the <chart:coordinate-region> element specify together a positioning rectangle."

Suggest:

The {{<chart:coordinate-region>}} element specifies a positioning rectangle for charts.

Proposal reads:

"For charts with a two-dimensional Cartesian coordinate system, the used intervals on the axes span a rectangular coordinate-region. Axis labels, tick marks, axis titles and data labels are not considered in determining the coordinate-region. The coordinate system is scaled so that the coordinate-region matches width and height of the positioning rectangle. The entire chart is located, so that the coordinate-region matches the positioning rectangle. "

Suggest:

The two-dimensional Cartesian coordinate system of chart types chart:area, chart:bar, chart:bubble, chart:gnatt, chart:line, chart:scatter, chart:stock and chart:surface, is contained by the positioning rectangle. Coordinate systems are scaled to lie within that rectangle.

Proposal reads:

"Charts of the predefined classes chart:radar, chart:filled-radar, chart:circle and chart:ring do not have a Cartesian coordinate system. For such charts the smallest bounding circle is considered, ignoring all axis labels, tick marks, axis titles and data labels. The rectangular bounding box of this circle is the coordinate-region. Where single data points have a chart:pie-offset greater zero those offset shall not contribute to an expansion of the coordinate-region; thus a pulled out pie segment is allowed to protrude from the coordinate-region. A chart:pie-offset at the series element in contrast shall contribute to the coordinate region.

 Circle or ring or the polar coordinate system of radar-charts respectively is uniformly scaled, so that the coordinate-region has maximal size, but does not exceed the size of the positioning rectangle. The entire chart is located, so that the coordinate-region is centered in the positioning rectangle. Producers should specify a square positioning rectangle for charts of these classes."

To some degree repeats itself.

Suggest:

The positioning rectangle for chart types chart:circle, chart:radar, chart:radar-filled, and chart:ring, is defined as the smallest bounding rectangle box of the smallest bounding circle.

I falter on:

"Where single data points have a chart:pie-offset greater zero those offset shall not contribute to an expansion of the coordinate-region; thus a pulled out pie segment is allowed to protrude from the coordinate-region. A chart:pie-offset at the series element in contrast shall contribute to the coordinate region."

Perhaps "greater zero" was meant to read: "greater than zero?"

Further the text (to me) seems to confuse *protrusion" from the coordinate region with "expansion" of the coordinate region. Even with a value greater than zero, a data may or may not protrude from the positioning rectangle. Depends on the size of the data point representation within. Conversely, expanding the coordinate space is different from the location of elements.

Suggestions? The proposal is very close but as you can see, it doesn't read smoothly to me.

Thanks!

> The proposal adds a new element <chart:coordinate-region> as child to the <chart:plot-area> element. It contains the position and size of the coordinate system excluding the axis labels. That makes the diagram independent of length of axis labels, which might change, if linked data changes, and it makes it easier for authors to align several charts.
