Create dot plots and strip charts for showing distribution of individual data points along an axis.
Each observation remains visible as its own mark in the Dot Plot Generator. Enter numeric values, choose a dot plot or strip-chart presentation, and read their positions against the axis to inspect clusters, gaps, repeated values, and possible outliers. Unlike a bar chart, this display does not aggregate observations into totals. A common surprise is that duplicate values are still separate observations, so several dots may share or occupy nearby positions instead of becoming one larger mark.
A concrete input and expected output from the current implementation.
Input
Plot type: Dot plot Values: 1 1 3
Expected output
A three-point dot plot with two dots at the axis value 1 and one dot at the axis value 3.
The input contains three observations. The value 1 occurs twice, so it contributes two dots; the value 3 occurs once and contributes one.
The generator treats every entered number as an individual observation and positions its mark according to that number on a common quantitative axis. Equal numbers therefore have equal axis positions. The distance between positions represents numeric distance, making a gap from 1 to 3 visibly larger than a gap from 1 to 2.
A dot plot makes repeated observations countable by arranging marks that occupy the same axis value. A strip chart also preserves one mark per observation, but presents the points as a strip and may separate nearby marks visually. In either view, mark count represents observation count rather than a calculated total, average, or histogram bin.
No. Its defining output is a mark for each entered observation. Repeated values reveal frequency through multiple marks, but the plot itself should not be read as a computed mean, median, or binned frequency table. Calculate those summaries separately if the decision depends on an exact statistic rather than the visible distribution.
Choose a strip chart when the main goal is to see the spread of individual observations and closely placed marks need visual separation. Choose a dot plot when repeated values and their counts are central to the question. Neither view is ideal for a very large dataset, where overplotting can make individual marks hard to count.
