Add specs to verify the behavior of PlotPanZoomStackGroup,
which is responsible for synchronizing the domain axis
between multiple sub-plots in a stacked plot view.
WTD-625.
Restore range tick marks; these were lost in refactoring
to support multiple subplots-per-view due to a missed
occurrence of an out-of-date interface usage. WTD-625.
When changes to pan-zoom bounds are made in one
subplot, this will effect the pan-zoom bounds of
other subplots. Ensure this occurs immediately.
WTD-625.
Utilize PlotPanZoomStackGroup; that is, utilize changes
such that a set of pan-zoom stacks can be treated as one,
while their domain axis synchronizes, and their range
axis does not. WTD-625.
Initially implement a synchronized pan/zoom stack,
which maintains the same domain axis bounds for all
subplots in a stacked plot view, but allows each to
have independent range axes. WTD-625.
Change plot style when in stacked plot mode, such that
plots stack as expected. (Without this change, the
gl-plot class's height of 100% will cause all plots to
fill the full vertical space, effectively acting
overlaid.) WTD-625.
Fix issues related to refactoring of view-level
to subplot-level behavior, such that previous
functionality is restored. This refactoring
supports introduction of a stacked-plot mode,
for WTD-625.
Begin refactoring Plot view to support stacked plots;
separate out behavior which needs to occur per-plot
from area which should occur per-view, and add a
handler for the Overlay mode. WTD-625.
Get/set mode from the plot mode switcher; only show
the switcher if there is more than one mode available
(which should only occur when there is more than one
telemetry object in the plot.) WTD-625.
Place elements of the PlotController into a separate
directory inside of the source folder for the plot
plug-in, in preparation for review and integration.
Part of ongoing plot transition to Angular, WTD-533.
