+        start(list of float): start positions of writables.
+        end(list of float): final positions of writables.
+        steps(int or float or list of float): number of scan steps (int) or step size (float).
+        relative (bool, optional): if true, start and end positions are relative to 
+            current at start of the scan
+        latency(float, optional): settling time for each step before readout, defaults to 0.0.
+        passes(int, optional): number of passes
+        zigzag(bool, optional): if true writables invert direction on each pass.
+        before_read (function, optional): callback on each step, before each readout. Callback may have as 
+            optional parameters list of positions.
+        after_read (function, optional): callback on each step, after each readout. Callback may have as 
+            optional parameters a ScanRecord object. 
+        title(str, optional): plotting window name.
