Plotting Data with Histogram Charts

The KS6800A PathWave Measurement Analytics software uses the Histogram as the default chart type to plot measurement data for integer and float data types.

To plot a Histogram chart:

  1. Select a field, which has the data type as either int32, int64, float64, or timestamp(ms) in the Fields dialog.

  1. In the Actions area, click Add field as new chart.
The Histogram chart is displayed for the selected measurement data.

The Histogram charts plot the measurement values (for the selected field) on the X-axis and the frequency of occurrence of measurements on the Y-axis. Each blue vertical bar indicates a certain range of measurement values obtained and the total number of measurements corresponding to each single value or range of values. If vertical dashed lines appear in red, they indicate the limits defined for a range of measurement data. You may modify the upper / lower limits using the Configure Dataset feature.

  1. To view the measurements in the distribution, click to select a chart.
  2. Hover the cursor over each bar in the distribution to view the range of values covered and the count of these measurements. The values depicted by each Histogram bar are displayed in the format: <Number of measurements in the range> [<Range lowest value>, <Range highest value>].

In the example shown above, the mouse pointer hovers over the fifth bar from the left. The corresponding data, which is displayed in the callout, can be interpreted as "72 measurements for sepal_width are found in the range of 2.8 to 3.067 units."
  1. Repeat steps 1 and 2 to plot the Histogram charts for other fields with integer or float data types.
  2. Click to view the Select Chart Type menu and change the chart to Pareto or Box and Whisker charts.
  3. Click to close the window for the displayed chart.
