Oscilloscope Settings
Various global Oscilloscope attributes and defaults
can be set using the Settings → Oscilloscope menu
command.
X axis
Min Length specifies the minimum length of the X-axis in the Chart Window. This value is used when the
chart is empty. In normal situations, the X-axis length is based on the range required by the curves being
displayed.
The Origin setting determines the initial state of the Shift to 0 toggle button. If set to Relative, then by
default the X-axis (time) will be shifted so that curves start at time 0. If set to Absolute, then the X-axis is
not shifted. This setting will affect all curves.
Y axis
Min Length specifies the default minimum length to be used for the Y-axis when new curves are being
added. After a curve has been added, then this value can be changed by setting the curve Properties → Axis
in the "Curve Selection List".
If "Auto Scale while polling" is enabled, then the Y-axis used in the Chart Window will be recalculated while
an Oscilloscope "run" is active. This prevents curves from being drawn "outside" the Chart Window if Y
values go outside the range of the current Y-axis. If this happens, then the Y-axis of the Chart Window will
be scaled so that the curve always remains entirely visible in the Chart Window.
Background
This selects the background color of the Chart and Navigation Windows. The different backgrounds are
shown below.
Interpolation
This is the default display style to be used when new curves are added. After a curve has been added, its
display style can be changed using Properties → Display in the "Curve Selection List".
