Excel does not have a Stiff Diagram chart option in the charts. But, we can create a Stiff Diagram in Excel by using a scatterplot chart and freeform diagram in the shapes tool. Tweaking a bit of coloring of the chart will give us the perfect Stiff Diagram. Here's how.

These are a few simple steps on how to create Stiff Diagram in Excel.

Step 1: Enter the values of cations and anions. Use the anion values in negative as shown below.

Step 2: Select 1, 3, and 5 (press Ctrl key, so select cells individually) and copy (ctrl+c).

Step 3: Right click on empty cell -> Paste special -> Transpose


Step 4: Select the data in this table (2, 3, 4)

select transposed data

Step 5: Now go to Insert -> Charts -> Insert Scatter

Step 6: Now assign the data labels by the values in the first table. Select the blue dots by click -> right click -> format data labels.
