How-To¶
Quick Start¶
Create your first dot plot in less than two minutes.
This example shows the simplest way to create a dot plot: a single column of numeric data. Quantum XL plots each value as a dot along a number line, stacking dots vertically when values overlap.
Goal¶
Create a dot plot showing the distribution of temperature readings from a single column of data.
Sample Data¶
Press Copy for Excel, then paste the table into a blank worksheet.
| Temperature |
|---|
| 68.1 |
| 69.5 |
| 71.2 |
| 71.8 |
| 72.0 |
| 72.3 |
| 72.5 |
| 72.5 |
| 72.8 |
| 73.0 |
| 73.1 |
| 73.2 |
| 73.4 |
| 73.5 |
| 73.8 |
| 74.0 |
| 74.2 |
| 74.5 |
| 75.1 |
| 75.8 |
| 76.3 |
| 77.0 |
| 78.4 |
| 80.2 |
| 82.1 |
Each row represents one temperature reading. The dataset has a dense cluster of values in the low 70s with a few isolated readings at the extremes.
Steps¶
-
Put the data in Excel
Press Copy for Excel above the table, click cell A1 in a blank worksheet, and press Ctrl+V. The header row lands in row 1 and the 25 data rows in rows 2 through 26.
-
Launch the analysis
From the Excel ribbon, select QXL Stat Tools → Analysis Tools → Dot Plot.
-
Select your data
Select cells A1:A26 (the header row plus all 25 data rows).
-
Configure the analysis
In the Dot Plot dialog:
- Data Columns: "Temperature" should be checked
Quantum XL automatically selects the single provided data column, so you don't need to change any options. Click Finish to generate the chart.
Result¶
Quantum XL creates a dot plot showing the distribution of temperature readings. Each dot represents one observation. You can see a dense cluster of dots in the 72 to 74 range, a gap between 78 and 80, and a few isolated dots at the high end (80.2, 82.1). This pattern is immediately visible because every individual data point is plotted.
