I appreciate your user perspective on this and I can see the usefulness of 
strictly defining only the plot size in some way. While obvious from the 
outside it's unfortunately much less so when trying to implement this.

Assuming we define the plot size only, then where should the legend be 
rendered ? On-screen you could argue the canvas size is infinite so it can go 
next to the plot even beyond the borders of the window. But what should happen 
with it when printed ?

Note the choice for pixels is historical. Nowadays people are more interested 
in millimeters or inches. That adds the challenge of getting proper screen 
resolutions from the system to convert this back to pixels on-screen.

And there are plenty more technical challenges. I believe most likely all can 
be solved, but it requires some thorough analysis of the report use cases, 
wishes and constraints.

I presume "Plot width" was the most dense the original author of that code 
could come up with a long time ago. Or originally there were no legends for 
the charts. Or we have changed chart rendering engines three times by now (and 
four times soon). Perhaps the original rendering engine did it differently.

It will first require someone to clearly describe the exact requirements of 
such an improved method of rendering. Feel free to focus your thoughts in an 
enhancement request!

Geert,

I was beginning to understand this point as well. Not that it makes 
sense in any way. Why would a user choose to define an image along with 
its accompanying text box by pixel? Further: the setting is "Plot width" 
--and not "Width of pie and accompanying text box" or something equally 
dense but accurate. "Plot" to me means "the image portion of this report."


I won't even go into the odd ways that these reports get jammed into a 
multi column report, since I can't begin to understand what the various 
factor are there. Suffice to say the result is not predictable or expected.


Now that I understand the idiosyncrasy, I will let the matter drop. 
Maybe someday someone will investigate an improved method for rendering 
these reports


Thanks,

David T.

I believe the legend and chart together are fitted into the dimensions you
set. If the text in the legend varies from report to report, that my explain
why the charts themselves vary as well.

I think yes, the percentage is based on the width of the ???printable??? area of
the report. (and it looks like the default is 100% or else it just
remembers what I used last)

As for number of slices, they all are set to the same value; it's just

affect overall pie size goes beyond my comprehension.

Dang. New mail client ate my screen shot! Next try...

Hello,

The attached screen shot shows three iterations of a standard 
Piechart. Each has its own set of accounts and slices, but each is set 
to plot its chart to the same 485 by 240 dimensions--and yet, each one 
is clearly a different size! While the first is an Expense piechart, I 
believe that they all use the same base Scheme code. And that doesn't 
explain why the two different Income Charts (Primary and Cap Gains) 
are sized differently.


Does anyone know why this is happening, and what might be done to get 
three identically-sized pie charts?
