Plotting Data with Pareto Charts
A Pareto chart, named after Vilfredo Pareto, is a type of chart that contains both Histogram bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. (source: Wikipedia)
The KS6800A PathWave Measurement Analytics software uses the Pareto as the default chart type to plot property data for string and boolean data types. Additionally, you can convert a Histogram chart to a Pareto. However, you cannot convert the default Pareto chart (for string and boolean data types) to a Histogram (or Box and Whisker) chart.
In the Pareto charts, the KS6800A software plots only individual values in the descending order of the frequency of occurrence. While the Pareto chart resembles a Histogram chart, the former plots the number of instances for absolute values than a range of values.
Plotting Default Pareto Charts
To plot a Pareto chart:
- Select a field, which has the data type as either string or bool in the Fields dialog.
- In the Actions area, click Add field as new chart.
- Repeat the previous steps to plot more charts.
- To view the measurements in the Pareto, click to select a chart.
- Hover the cursor over each bar in the Pareto to view the absolute values covered and the count of each value. The values depicted by each Pareto bar are displayed in the format: <Number of occurrences> <Absolute value> .
- Click
to close the window for the displayed chart.
Converting Histogram Charts to Pareto
Use the following steps to convert a Histogram chart (plotted by default for integer or float data types) to a Pareto chart.
- Click to select the Histogram chart, which you wish to convert to Pareto.
- Click
to view the Select Chart Type menu.
- Select Pareto to plot the corresponding chart.
- Optionally, you may modify the plotted chart in several ways to enhance analysis.
- Click
to close the window for the displayed chart.
