The TestLogger software gathers an immense amount of high precision data from the RC car in real-time - for example in this application, speed, steering and throttle information are visualized. Each measurement is paired with a location information, which tells where the RC car was located at the time of measurement.

Something that we found amazing was that the RC car location information is actually calculated in real-time by tracking the orientation and speed of the RC car itself - it is not relying on GPS or any other positioning system!

In this example, the RC car data is used to dynamically color the path of the RC car based on the selected data set. For example, when "Speed" is analyzed, low speeds are colored as white and high speeds are colored as red.

Dynamic line coloring is a powerful feature which can serve many different needs. The best thing about it is that it doesn't compromise performance, meaning that you can use it just as well with 100 data points or 100 million data points.

In addition to dynamic coloring by separate Value data set there are also more dynamic coloring modes available:
