Flexicharts

Library
Custom new
Built-in

Flexicharts provide a powerful and flexible way to make custom charts. Select a built-in chart from the library above, use the “chart creator” tool, or look at the examples and information below to get started. Complete documentation is also available.

One way to think about how this works is that you start with a big collection of data and then massage that into something useful to display. That is, given the summary data of all of your rides, you choose or construct x and y values to chart.

Examples

Copy any of these into the prompt above and hit the enter key to show the chart.

The distance for each ride (this sets y-axis to distance, and the x-axis shows the date by default):

chart().distance()

Time spent riding for each week, and training load for each month:

chart().duration().group_by(week).aggregate(sum);
chart().load().group_by(month).aggregate(sum);

A histogram of ride lengths (showing how many 0 to 10km rides, 10 to 20km etc. there are):

chart().distance().group_by(range(10)).aggregate(count)

The five longest rides as a table, and the longest ride for each month as a table:

chart().distance().max(5);
chart().distance().group_by(month).aggregate(max).table();

PWC170 versus 20 minute effective power for the best 20 minute effort of each month, with color indicating the long term stress at the time of the ride:

chart().epower_curve(1200, 'y').group_by(month).aggregate(max).epower_curve(1200, 'x').pwc170(0.5, 'y').day_lts('color').color('blue-gold')

Average power versus average heartrate for all three minute intervals, with the color of each point indicating LTS at the time of the ride:

chart().segment('3:00 interval').segment_power('x').segment_heartrate('y').day_lts('color')

Data sources

For ride summary data

  • chart().total_time([axis])
  • chart().duration([axis])
  • chart().moving_time([axis])
  • chart().distance([axis])
  • chart().climbing([axis])
  • chart().work([axis])
  • chart().epower([axis])
  • chart().intensity([axis])
  • chart().variability([axis])
  • chart().decoupling([axis])
  • chart().load([axis])
  • chart().trimp([axis])
  • chart().avg_cadence([axis])
  • chart().avg_speed([axis])
  • chart().avg_heartrate([axis])
  • chart().avg_power([axis])
  • chart().avg_temperature([axis])
  • chart().max_cadence([axis])
  • chart().max_speed([axis])
  • chart().max_heartrate([axis])
  • chart().max_power([axis])
  • chart().max_temperature([axis])
  • chart().min_temperature([axis])
  • chart().power_curve(seconds, [axis])
  • chart().epower_curve(seconds, [axis])
  • chart().pwc130([r2, [axis]])r2, the correlation coefficient, defaults to 0.5.
  • chart().pwc150([r2, [axis]])
  • chart().pwc170([r2, [axis]])
  • chart().lrbalance([axis])
  • chart().power_zone(index, [axis])
  • chart().hr_zone(index, [axis])
  • chart().date([axis])
  • chart().day_lts([axis]) — The LTS value for the day of the ride.
  • chart().day_sts([axis])
  • chart().day_sb([axis])

axis can be either 'x', 'y', or 'color' for charts, or any string for tables, and defaults to 'y' if not specified.

For segment data

First use chart().segment(name) to select the segment.

  • segment_duration([axis])
  • segment_distance([axis])
  • segment_climbing([axis])
  • segment_speed([axis])
  • segment_power([axis])
  • segment_heartrate([axis])
  • segment_cadence([axis])
  • segment_epower([axis])
  • segment_work([axis])
  • segment_vam([axis])
  • segment_decoupling([axis])

For training load data

  • chart().lts()
  • chart().sts()
  • chart().sb()

Manipulation functions

  • group_by(fn)day, week, month, year, all_time, range(n) or custom function.
  • aggregate(fn, [fns])sum, average, max, min, max(n), min(n), count or custom function. fns maps custom axes to functions.
  • filter(fn)this_year, this_month, this_week, last_year, last_month, last_week, date_filter(year, [month, [day]], [year, [month, [day]]]), on_monday, on_tuesday, on_wednesday, on_thursday, on_friday, on_saturday, on_sunday, or custom function.
  • map(fn, [axis]) — For custom functions.
  • rebase_dates(year, [month, [day]]) — To force different date ranges to overlap.
  • accumulate()y values are accumulated.
  • trendline([bandwidth]) — Loess trend line. bandwidth defaults to 0.5.

Charting functions

  • name(name)
  • color(scale_name, [alpha]), color(scale, [alpha]), color(options), color(color) or color(color, fill_color)
  • x_axis(min, max), x_axis(options), x_axis('fit'), y_axis(min, max), y_axis(options), y_axis('fit') or color_axis(min, max)
  • line(options)
  • points(options)
  • columns(options)
  • on(chart_number)
  • inspect() — Logs the data object to the browser’s developer tools console.

Table functions

  • table([format_map]) — optional map {axis: {unit: _, round: _, fixed: _}}, where unit can be 'miles', 'feet', or 'fahrenheit', round is a number, fixed is a number, and all three are optional.
  • max([count])
  • min([count])
  • count()
  • sort(axis, [ascending])ascending is false by default.
  • reverse()
  • limit([count])
