Rozmiar glifów

fig = figure(x_axis_label="Rebounds", 
             y_axis_label="Points")
fig.circle(x="rebounds", y="points",

           source=source, size=12)

output_file(filename="size_12_scatter.html")
show(fig)

wykres punktowy – rozmiar 12

Kolor obrysu glifów

fig = figure(x_axis_label="Blocks", 
             y_axis_label="Points")
fig.circle(x="blocks", y="points", 
           source=source, size=10,

           line_color="red")

output_file(filename="red_lines.html")
show(fig)

kolor obrysu glifów – wykres punktowy

Kolor wypełnienia glifów

fig = figure(x_axis_label="Assists", 
             y_axis_label="Blocks")
fig.circle(x="blocks", y="points", 
           source=source, size=12,

           fill_color="red")

output_file(filename="red_circles.html")
show(fig)

kolor wypełnienia glifów – czerwony

Przezroczystość glifów

fig = figure(x_axis_label="Free Throw %", 
             y_axis_label="Field Goal %")
fig.circle(x="free_throw_perc", 
           y="field_goal_perc", 
           source=east, size=10,

           fill_alpha=0.2, legend_label="East")

fig.circle(x="free_throw_perc", 
           y="field_goal_perc", 
           source=west, size=10, 
           fill_alpha=0.2, fill_color="red", 
           legend_label="West")

output_file(filename="transparent.html")
show(fig)

przezroczystość glifów – wykres punktowy

Aktualizowanie glifów

fig = figure(x_axis_label="Steals", 
             y_axis_label="Points")

circle = fig.circle(x="steals", y="assists", 
                    source=source, size=10,
                    fill_color="green")

output_file(filename="original.html")
show(fig)

circle.glyph.size = 20

circle.glyph.fill_color = "orange"

output_file(filename="updated.html")
show(fig)

oryginalny wykres punktowy
