Progressive OPF lesson

Make a comparison you can inspect

Use honest magnitude bars, visible units and one shared dataset for the chart and table.

Each preview is a prepared render of its complete OPF example. The selected step records its render toolchain separately from the editable source.

Step 1

Start with the actual values

A bar chart compares fictional values of 5.8 and 6.7 minutes. The value axis includes zero.

Try this

Change one numeric value while keeping the unit and the illustrative label.
