X-Y plot
This is a chart for two channels, showing on a display with x and y axes. Both channels must have the same sample rate. A sample rate column shows in the channels list.
The X-Y plot shows the history of the data over a time period, until it is reset. For example, longitude and latitude values from GPS input may be used to plot a test vehicle’s path.
- X axis (default): Display a single x-axis inheriting the properties of the first channel added to the chart.
- Y axis: (default): Display a single y-axis inheriting the properties of the second channel added to the chart.
The following options are available from the menu. Click the options menu button:
- Freeze: Select to pause the data display. Deselect to resume live data.
- Properties: Open the chart properties dialog box.
- Reset: Select to clear the chart during a test run.
- Show legend: Select to show a legend of channel names and colors in the field of the chart.
- Plot points: Select to show data as points (x,y) on the plot.

After entering information in the X-Y plot properties dialog, click the OK button.
Y-Axis
- Scaling: Select the Y-axis scaling mode.
- Automatic (default): Y-axis lower and upper values are set automatically based on current and past readings.
- From hardware: Y-axis lower and upper values are based on the user defined Range min and Range max parameters specified in the test setup.
- Fixed: Y-axis lower and upper values are based on the user specified Min and Max values.
X-Axis
- Scaling: Select the X-axis scaling mode.
- Automatic (default): X-axis lower and upper values are set automatically based on current and past readings.
- From hardware: X-axis lower and upper values are based on the user defined Range min and Range max parameters specified in the test setup.
- Fixed: X-axis lower and upper values are based on the user specified Min and Max values.
Time / Grid
- Time window (ms): Specify the span of the X-axis in milliseconds. Note that a value that is too large can cause performance issues.
- Hide gridlines: Select to hide the chart gridlines.
