Hello John,

You can use the NVennSeries object to display different logical relations between sets, including such that are not classified as Venn diagrams. You add contours (that actually represent sets) and you have to specify a shape, position, size and orientation for each contour.

We have examples for 3, 4 and 5 set Venn Diagrams - these are diagrams that show all possible logical relations between the sets. The contours in these diagrams have specific positions (and orientations) and we are using some constants to store these.

Thanks, I have looked at the examples and I am trying to apply the following example values to building the correct contours and labels. I find myself confused by the use of the constant values provided in the code pertaining to center, dimensions.

I have a count from a query where...

(a = 1 and b = 'hello' and c = 'Cat') == 4 CENTER

a = 1 = 20, b = 'hello' = 15, c = 'Cat' = 4 INDIVIDUALS

a AND b = 7, a AND c = 4, b AND c = 4 COMBINATIONS

Can you provide a code fragment for setting the size, dimensions etc for this?
Regards.

Hi John,

Currently the Venn diagram cannot be bound to any kind of data source. It has to be populated by adding contours programmatically as demonstrated in the examples.

After the download the only options I see are sql related (Ole, ODBC etc) or excel through the databinding manager (asp.Net 3.5)
Thanks.
