Transform Charts

KS6800A PathWave Measurement Analytics software has a feature called Data Transform. It can be used to temporarily modify the data used in the analysis and chart. In other words, data transform feature does not modify the source data itself.

To access the Transform feature:

  1. You need to have at least one chart in your analysis before you can use the Transform feature. To start an analysis and chart within a dataset, please refer to Plotting Data as Charts.

  2. Select one chart to which the data transform will apply (transform can only apply to one chart at a time). If no chart is selected, the radio buttons on the Transform tab will be disabled.

  3. There are four pre-defined Transform formulas available as shown below.

  1. There are 3 possible axes (X, Y, T) that you can apply to the transformation.

    1. X axis is for x-axis of the chart.

    2. Y axis is for y-axis of the chart.

    3. T axis is not available right now, it is for a chart with E data (e.g., environmental chart).

  1. The details of the Transform formulas are shown in the table below. The variable v in the formula represents the chosen axis.

No.

1

(10*v)+0

linear equation

2

10^(v/10)

exponent formula

3

logarithm formula

4

(1*v)+(-1)*v1)+0

linear equation

  • v1 is the data with numeric type

 

  1. These Transform formulas are only applicable on numeric data axes. If the axis is non-numeric, a warning will display and the Transform selected chart button is disabled.

You can only apply one transform formula for each axis or the same transform formula for both axes.
  1. After inputting the values, click Transform selected chart.

The transformed chart displays.

If the result of the transform formula is too large, the following message displays.

  1. To remove the applied transform, select the chart and click Clear & Reset Transform.
