Plots and tools

2D Analyzer offers various possibilities to visualize measurement data.

All plots can be prepared and used later to compare data of multiple measurements loaded in Analyzer.

Important

All plots and tool windows positions are saved in Templates!

Important

As inputs for plots and tool, also Special Channels can be selected!

When creating new plots at higher license levels with activated User Management !!!Link!!! Plots can be created either only for current User or for all Users of Race installation.

Addtional manual

For all plots Phases can be used to organise/filter the currently displayed values of a plot, for e.g., removing in- and out-lap from Min-/Max-table. A preview of current phase selection is shown at bottom bar of plots.

Multi-Circuit (Google Maps overview)

GPS/GNSS positions from measurement are drawn on Google Maps background image.

Important

Only for laps currently shown in moving window lines are drawn in Multi-Circuit.

Multi-Circuit can be opened via Analyzer-tab Functions, by pressing <m> or using Header window icon.

Attention

For loading Google Maps background image valid internet connection is required!

Attention

For correct drawing of driving line, the Special Channels GPS_Latitude, GPS_Longitude and GPSValid must be set correctly!

Min-/Max-table

A Min-/Max-table serves as a quick overview of minimum, maximum and average values of some channels of a measurement lap by lap.

Important

For every lap a new line is created!

Min-/Max-table can be opened via Analyzer-tab Functions, by pressing <Alt>+<m> or using Header window icon.

Min-/Max-table

Minimum and maximum values of respective columns are highlighted in green and red.

The percentage distribution of the values per column is shown in blue.

Attention

AVG-value on bottom of Min-/Max-table shows the average value only of the Min-/Max-table values per column!

  • Colors - Uni: XY-Plot data is shown in measurement color - Color Channel: Setting any channel of measurement as color channel for drawing line

    Important

    Via Color Scale different options can be chosen for coloring the lines.

    • By laps: For every lap of currently loaded measurement another color is used for drawing XY-Plot data

    • By measurement file: XY-Plot data is shown in measurement color

  • Select: Select area of XY-Plot to be displayed

  • Edit limits: Set limits manually

  • Fixed Ratio: Fix ratio of axes

  • Dynamic autoposition: Automatic catching when current selection and thus XY-Plot data changes

Histogram

A histogram is a graphical representation of the distribution of numerical data of a channel.

Important

It is an estimate of the probability distribution of a channel data considered as a continuous variable. To construct a histogram, the first step performed by 2D software is to “bin” the range of values of the selected channel - that is, divide the entire range of values into a series of intervals - and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlapping intervals of a variable. The result is a frequency of occurrence (~ a probability) for the instantaneous value of a channel to fall in one specific bin.

Min-/Max-table can be opened via Analyzer-tab Functions, by pressing <Alt>+<F1>.

Important

Histogram are very suitable when it comes to suspension data analysation.

    • Split channels: Activate if obove described split channels should be used to create multiple histogram windows depending on split channel setting

    • Phase conditions: Reducing range of data (e.g., displaying histogram from rear suspension sensor with data from whole phase (e.g., fastest lap) but only when speed is between 100 and 150 km/h)

    • Laps: Split diagram by laps

  • Split data by:

    • None (1 diagram): Use only one histogram window for displaying data

FFT

A fast Fourier transform (FFT) algorithm computes the discrete Fourier transform (DFT) of a sequence, or its inverse.

Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa.

Track mode

Graphical presentation of track with channel values at defined positions.

Track mode can be opened via Analyzer-tab Functions, by pressing <x>.

Important

A 3rd dimension is achieved by using a so-called color channel.

Status Bits

With Status bits tool bits of channels can be linked to an text information.

Important

Status bit always shows values of current cursor position in moving window.

Status Bits can be opened via Analyzer-tab Functions.

DIAG Bit Maps

With DIAG Bit Map tool bits of channels are displayed in coloured boxes on current cursor position (first line) and over whole measurement (second line).

Important

First line shows bit value on current cursor position in moving window. Second line shows bit value over whole measurement, to see if bit is TRUE somewhere in measurement.

DIAG Bit Map can be opened via Analyzer-tab Functions.

Dynamic Test System (DTS) - DTS Tool

The Dynamic Test System software tool (DTS Tool) allows for a fast, table-oriented overview of the already recorded measurements in regard to dynamic vehicle testings (Brake Tests, Acceleration Tests, ELK Test, Slalom) on computer.

Important

Analyzer DTS Tool can be used execute dynamic vehicle data evaluations with every set of measurement data (Automotive testings, RaceTrack data for vehicle or driver analysations.

Output of Analyzer DTS Tool is a report window with all important information to set tests (Brake time, brake distance, max. accereleration, MFDD, …) which can be exported als Excel file.
