Plotting Data with Line Charts

The Line chart (known as Summary Line chart in the KS6800A PathWave Measurement Analytics) connects the mean values of the plotted data, against each value of a selected field, which is plotted on the X-axis. The Y-axis shows the range of measurement values obtained. The red-dashed lines that indicate the limits (if defined) are displayed on the horizontal scale in this case.

In the KS6800A PathWave Measurement Analytics software, you can plot a Summary Line chart only after you plot a Scatter chart.

A Scatter chart, converted from a Pareto chart for the string data type, cannot be plotted as a Summary Line chart.

To plot the Line chart:

  1. Plot a Scatter chart for one of the fields containing measurement data (with either integer, float or date/time data types) against another field as X axis. For more information on how to plot Scatter charts, see Plotting Data with Scatter Charts.

  1. Click to view the Select Chart Type menu.
  2. Select Summary Line to plot the corresponding chart.

The Summary Line chart for the plotted data appears. Note that the Select Chart Type menu icon changes, indicating that Summary Line chart has been plotted.

  1. To view the measurements in the summary line, click to select a chart.
  2. Hover the cursor along the summary line to view the mean values plotted at each point corresponding to the values on the X axis. The values depicted by the summary line are displayed in the format: <Mean value> . The corresponding value on the X axis is highlighted in a callout.
In the example shown above, the mouse pointer hovers over the tip of the summary line, which shows the mean value corresponding to the value plotted for the field added as X axis. The plotted data can be interpreted as "A mean value of 2.026 units of petal_width is obtained for the species 'virginica'.".
  1. Click and select Scatter to plot the Scatter chart for the same measurements.
  2. Click to view the default Histogram chart for the plotted field.
  3. Click to close the window for the displayed chart.
