22 - Configure a Vertical Bar Chart

📖 Task Introduction

Return your attention to CHART TYPE . This time we can simply leave the chart type to be the default: Vertical Bar Chart.

🔨 Task Instructions

1. To set the X-AXIS of the Chart, select to X-AXIS dropdown and change it to distance.
2. Click exact value and change it to optimal. By choosing optimal, the number of buckets is equal to the square root of the difference between the maximum and minimum values of the column.
3. Select the Y-AXIS Series 1 dropdown (i.e. where it says Row count) and change it to speed — the field you created earlier in this tutorial with an Expression Board.
4. Select the calculation dropdown of the Y-AXIS (i.e., where it says Exact values) and change the calculation type from Exact values to Mean.
5. Finally, click Compute & save to create the chart.
