A zoom of 1.0 implies 300 meters/pixel (roughly 10 km. per cm. of screen).
The location of the landmark determines the origin of range overlay information.
The second set of radio buttons affects tic mark options.
The default is to center on the local radar and be independent of what is happening in other frames. It is possible to force all linked frames to center on a fixed latitude and longitude or to force all linked frames to center on a reference frame. Otherwise the reference frame has no effect.
The "Set Links" item brings up a links widget to define which frames share this centering information.
It is possible to force all linked frames to reference a fixed latitude and longitude or to force all linked frames to share the landmark in a reference frame. Otherwise the reference frame has no effect.
The "Set Links" item brings up a links widget to define which frames information.
The "TimeSeries" submenu enables color bscan plots based on time. Each pixel along the horizontal is assigned a constant interval of time which enables compression or expansion of time plus revealing gaps in the data.
You have to click "OK" or one of the Replot options to get the time series parameters activated.
Start and stop times are set in the "Sweepfiles" widget. A relative time in the "Start Time" entry shifts the start of the plot. A relative time in the "Stop Time" entry can be used to define the time span.
The default is to plot increasing time from left to right relative to the indicated times with the range increasing upward.
For aircraft data it is possible to fix the center of the plot on an msl altitude and shift the data such the data bin closest to this altitude is at the center of the screen.
In flights where the instrument's fixed angle is changing between nadir and zenith, the "Automatic" option changes increasing range to be either up or down depending on the fixed angle of the instrument.
