The recent RideFileCache patches added functions to
pre-compute mean-max and distributions. This enabled
this patch to add plotting histograms for a date
range rather than a specific ride.
It supports all the same data series as before but will
allow you to select a season from a new combo box.
I have refactored a fair amount of the code, but kept the
original code in PowerHist as close to unchanged as I could
since I did not want to disturb existing functionality.
There is no support for Zoning historic data -- this requires
an update to the RideFileCache.
This patch enables more data series to be plotted on a CP plot.
We can now show curves for heartrate, cadence, speed and torque
as well as the original power and energy.
The CP code is refactored into the plotting functions and a new
RideFileCache that precomputes the mean-max as well as distribution
data (for a later patch to show histograms across date ranges).
The code for computing mean-max values has been re-written and
significantly optimised by;
* computing 1s intervals up to 5mins only
* computing 20s intervals for the remainder of the ride
* downsampling data to 5s samples for longer durations
* using a binary file format (cpx) for faster read/aggregation
* using multiple threads
Testing on an old Athlon dual-core showed an increase in performance
over the old cpi code of approximately x20, but since new data series
are now computed it is only x4 faster. Quad/Octo core systems will
show a greater performance increase though.
The code in HistogramWindow::rideSelected() to check
HR and Power zones have been configured for the
ride just selected contained a typo; the power range
would be set to HR and the hr range would be set to
power. This resulted in the wrong options being shown
in the drop down box.
This patch fixes this behaviour.
This patch introduces new functionality for working with
Heartrate based data.
* HR Zones can be defined, from Resting, Maximum and Lactate HR
* TRIMP metrics are calculated; TRIMP, TRIMP100 and Zonal TRIMP
* TRIMP metrics can be used to drive the PMC
* Time In Zone metrics for HR have been added
* Histogram window will now work with Power/HR zones
* User Settings have been added to record gender, weight and others
* RideFile has a new tag "Athlete" which is set to the athlete name
Fixes#140
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.
And pay attention to MainWindow::activeTab, such that only the active
tab redraws itself when changing rides. This change really increases
GC's responsiveness when scrolling through the ride list.
With the introduction of the rideSelected signal the RideFile was
opened (as previously) by the RideSummaryWindow::htmlSummary()
member. In some cases, this signal was processed by RideSummary window
AFTER the other charts (AllPlot etc) this results in 'No data' being
shown on other charts.
This patch moves the file reading to RideItem::ride() which was previously
a public RideFile * (that is now a protected member ride_). As a happy by
product it removes the need to check if the file has already been read
across all other functions ensuring in-core values are not accidentally
overwritten. The read errors are made available by a new RideItem::errors()
member.
This modification is required to support the RideImportWizard in freeing
loaded RideFiles during batch import to ensure virtual memory is not
exhausted when large numbers of files are imported at once. This modification
is also included in this patch.
