From efb1fa44b81419841d7c92104a69987c256a0028 Mon Sep 17 00:00:00 2001 From: Dirk Hohndel Date: Thu, 15 Sep 2011 09:10:08 -0700 Subject: [PATCH] Print the end temperature of the dive Currently we print the temperature every five minutes. Especially with dive computers that keep rather frequent temperature samples that means that we have one more interesting data point that we don't label: the surface temperature at the end of the dive. This patch adds some logic to try to print the last temperature sample that was recorded before the dive ended - unless that same value has already been printed (to avoid silly duplications on dive computers with less frequent sampling) Signed-off-by: Dirk Hohndel Signed-off-by: Linus Torvalds --- profile.c | 39 +++++++++++++++++++++++++++------------ 1 file changed, 27 insertions(+), 12 deletions(-) diff --git a/profile.c b/profile.c index a4608c5..fdbbcdf 100644 --- a/profile.c +++ b/profile.c @@ -328,35 +328,50 @@ static int setup_temperature_limits(struct dive *dive, struct graphics_context * return maxtemp > mintemp; } -static void plot_temperature_text(struct dive *dive, struct graphics_context *gc) +static void plot_single_temp_text(struct graphics_context *gc, int sec, temperature_t temperature) { - int i; + int deg; + const char *unit; static const text_render_options_t tro = {12, 0.2, 0.2, 1.0, LEFT, TOP}; + if (output_units.temperature == FAHRENHEIT) { + deg = to_F(temperature); + unit = "F"; + } else { + deg = to_C(temperature); + unit = "C"; + } + plot_text(gc, &tro, sec, temperature.mkelvin, "%d %s", deg, unit); +} + +static void plot_temperature_text(struct dive *dive, struct graphics_context *gc) +{ + int i; int last = 0; + temperature_t last_temperature, last_printed_temp; if (!setup_temperature_limits(dive, gc)) return; for (i = 0; i < dive->samples; i++) { - const char *unit; struct sample *sample = dive->sample+i; + if (sample->time.seconds > dive->duration.seconds) + break; /* let's not plot surface temp events */ int mkelvin = sample->temperature.mkelvin; - int sec, deg; + int sec; if (!mkelvin) continue; + last_temperature = sample->temperature; sec = sample->time.seconds; if (sec < last) continue; last = sec + 300; - if (output_units.temperature == FAHRENHEIT) { - deg = to_F(sample->temperature); - unit = "F"; - } else { - deg = to_C(sample->temperature); - unit = "C"; - } - plot_text(gc, &tro, sec, mkelvin, "%d %s", deg, unit); + plot_single_temp_text(gc,sec,sample->temperature); + last_printed_temp = last_temperature ; + } + /* it would be nice to print the end temperature, if it's different */ + if (last_temperature.mkelvin != last_printed_temp.mkelvin) { + plot_single_temp_text(gc,dive->duration.seconds,last_temperature); } } -- 2.45.2
