How to apply shading/pattern to overlapping parts of a Venn-diagram in PPT 2019

A Venn diagram uses overlapping circles to illustrate the similarities, differences, and relationships between categories, or groups. Similarities between groups are represented in the overlapping portion, differences are represented in the non-overlapping portions of the circles. Each group contains one circle.

To create a Venn-diagram:

Insert tab, in the Illustrations group, click SmartArt button.

In the SmartArt Graphic gallery, click the Relationship category, click Basic Venn and click OK.

First type all the text in the circles.

Below an example, in the total number of goals scored how many are the consequence of a corner or free kick.

By default you get a transparent color in the overlap. But what if you want to work with a fill/pattern on the overlap? For that you need a workaround.

To apply a fill or pattern to the overlapping parts you will need the Merge Shapes function.

First you will have to convert the SmartArt into separate shapes. To be on the save side do this on a copy of the slide. Don't do this if you are not sure there will be changes or things to add after the transformation. You will no longer have a SmartArt object.

Under Smart Art Tools, choose Design tab and click the Convert button, select Convert to Shapes.

At first glance, nothing seems to have changed. But on the ribbon you will see that it no longer says SmartArt, but it says Drawing Tools.

The drawing is still grouped. Go to Layout tab - Arrange group - Group button and choose Ungroup.

Cut and paste the text in the circles onto the underlying slide. If you don't do this, you will run into problems when joining the shapes.

Now select the individual circles (the top one first) and choose the Layout tab, Insert Shapes group - Merge Shapes button - Fragment.

Now the two overlapping parts have become separate objects. You can now provide it with a fill or pattern. Just select the overlapping part and apply whatever fill of pattern you want.

Select the overlapping shape, right-click on it and choose Format Shape. In the Format Shape task pane, choose the Pattern Fill radio button, choose your pattern, and determine the foreground and background color if necessary.

Select and paste the text back into the circles.
