Settings

The library has settings (global variables). These might change during an update, but have been fairly stable over time.

Functionality

significant_decimals = 8 # how many digits to show
significant_eps = 1e-8 # default Y-step
max_zoom_points = 20 # number of visible candles when maximum zoomed in
axis_height_factor = {0: 2} # top axis is twice as tall as the others
clamp_grid = True # clamp crosshair by default, press g to toggle
right_margin_candles = 5 # whitespace at the right-hand side
side_margin = 0.5 # show half a period on each side of the center of a candle
lod_candles = 3000 # when to start sampling candles
lod_labels = 700 # when to start sampling candles
cache_candle_factor = 3 # factor extra candles rendered to buffer
y_pad = 0.03 # 3% padding at top and bottom of autozoom plots
y_label_width = 65 # Y-axis width
long_time = 2*365*24*60*60*1e9 # when X-axis skips over to showing years
display_timezone = None  # default to local
winx,winy,winw,winh = 400,300,800,400 # (non-maximized) window positions

Colors

legend_border_color = '#777'
legend_fill_color   = '#6668'
legend_text_color   = '#ddd6'
soft_colors = ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf']

Slightly more private variables

They control the guts of the lib.

app = None # PyQt app
windows = [] # holds all active windows
timers = [] # holds all active timers
sounds = {} # holds all active sounds
epoch_period = 1e30 # default time between candles to something large
last_ax = None # always assume we want to plot in the last axis, unless explicitly specified
overlay_axs = [] # for keeping track of candlesticks in overlays
viewrestore = False # controlled via autoviewrestore()
master_data = {} # lookup if embedding in your own PyQt window
