If the model plot cannot be refreshed when data
is invalid, the plot needs to be hidden since the
qwtplot3d api does not redraw empty plots and does
not have any methods for clearing the canvas.
This workaround just hides the plot and shows a label
when the plot is invalidated.
Fixes#429.
With v3 we have removed the sunken frames on
all the plots to make for a cleaner 'flat' feel
to the charts. The 3d plot has now been adjusted
to be in line with the rest of the plots.
A new config pane for defining color preferences for chart
curves, shading, background and grid lines et al. Default values
echo the current hard-coded values.
The best interval dialog rounded intervals to the nearest second
due to a casting of a double to int. This was introduced by Mark L
during the intervals code patch and is an error.
All the plots have now been adjusted to correctly determine if a ride
point is within an interval. Related cropping and binning issues in
3d plot an Histogram plot have also been corrected.
fixes#15
Scrolling up and down the ride files is painfully slow when
3d is compiled in. This patch uses a setActive mechanism in
the same fashion as the pfpv and performance manager tabs.
Additionally, a recent patch to support user preferences for
units added a settings lookup that was called for every point.
This is also fixed.
fixes#16
The pedal force channel was incorrectly named - it should have been
the torque value. The AEPF/CPV values are derived from the power
cadence and cranklength. This is corrected with this patch.
Additionally, the axis labels positioning has been amended to be
more appealling and position more appropriately.
A new tab on the ride analysis view for analysing ride data in three
dimensions. Interval selection is supported and a z-axis slider is
available for helping to identify data in the z-plane. A color legend
is displayed since coloring is independent of x/y/z values.
Coloring and Z axis values are averages for associated values of x/y.
The code requires qwtplot3d to be installed (see gcconfig.pri.in) and
with older Mac dev envs you will need to add -lz to LIBS too. (LIBS += -lz).
On Linux qwt3d_function.h needs a #include <stdio.h> added to compile.
Greg Steele helped design and test.
There are 2 open issues x/y/z axis labels occasionally appear in the
wrong place. lastly, the bin selection is for X&Y bin sizes and it
would be better to have separate sliders.
