1. Scatter plots show data as it relates to 3 variables. Select the three variables.
2. In this example you can see RPM vs Total Lambda Error vs Lambda. This graph shows there is very little error between 2000-4000rpm and .800-.900 lambda.
3. Optionally, you can right-click on the background, this options allow you to change the color range to suit your screen and surroundings better.
