# Further options of visualization in DigiRhythm

DigiRhythm additionally contains some deeper visualization possibilities. - the function daily_activity_wrap_plot could be used to visualize the activity over time per day - the function plot_quadro is a possibility to combine different forms of visualizing activity (actogram, average activity, DFC and HP and daily activity) - the function plot_actogram_avg_activity will show what happens, if Hassan wrote the code

First, we start by loading a dataset, removing the outliers, resample it to 15 min and choose the activity to study.

    library(digiRhythm)
    data <- digiRhythm::df691b_1
    data <- remove_activity_outliers(data)
    data <- resample_dgm(data, 15)
    activity <- names(data)[2]
    head(data)
    #>              datetime Motion.Index Steps
    #> 1 2020-08-25 00:00:00           20     8
    #> 2 2020-08-25 00:15:00           52    46
    #> 3 2020-08-25 00:30:00           61    39
    #> 4 2020-08-25 00:45:00           29    18
    #> 5 2020-08-25 01:00:00           83    26
    #> 6 2020-08-25 01:15:00           50    23

# Daily Activity Wrap

Now we proceed to plot the daily activity. User can decide to plot the activity during the time of one day. Or to plot a huge plot including a number of day-plots. User has to define the activity to plot. Additionally, user has to define the activity_alias, similar to the actogram. Start and end date have to be defined by the user, using the format “%Y-%m-%d”. Afterwards, sampling_rate of the data has to be defined. The sample size has to be bigger or equal to the sample size of the dataset. With “n_cols”, the user is able to decide how many graphs/days should be shown in a row of the plot. User has the possibility to save the plot directly, using this function.

    activity_alias <- "Motion Index"
    start <- "2020-08-25" # year-month-day
    end <- "2020-10-11" # year-month-day
    sampling_rate <- 15
    ncols <- 3 # number of columns
    # save <- 'sample_results/daily_wrap_plot' #if Null, doesn't save the image
    my_daily_wrap_plot <- daily_activity_wrap_plot(data, activity,
      activity_alias,
      start,
      end,
      sampling_rate,
      ncols,
      save = Null
    )
