In Excel, you can create diagrams, flowcharts and other visual aids of quite high complexity, without using any dedicated graphic design software. All you need for this purpose is utilizing the Insert tab and the Illustrations group within it. The Illustrations group includes pictures, shapes, icons, 3D Models, SmartArt, etc.
And within Shapes there is a group of Lines. Most of them are Connectors that can be attached to any of the illustrations and connect them with any others. The last three lines in the group, namely Curve, Freeform Shape, and Scribble, are not Connectors, but allow you to enrich the Excel collection of graphical creations with your own customized shapes/drawings.
Here's an example of possibilities offered by precise connections of the shapes. Just a simple idea:
Instead of adding your graphic elements one by one, you can choose from available selection of SmartArt graphics. Once you insert all your graphic elements in a desired order/arrangement, you can connect them by following these steps: - select appropriate connector from the Lines collection
- click anywhere on the first graphic element; connection points will appear for you to choose one of them and attach the connector line
- drag the cursor to a connection point on the second connection object
- to adjust appearance of the line, you can right-click on it and choose "Format Shape" to modify the line colour, thickness, style etc.
You can also add text/labels to your graphic elements by right-clicking on them and selecting "Edit Text". The elements can be repositioned if needed, and the connectors will remain attached to and moved with the graphics. Pretty convenient.
