y4 = [math.pow(i,2) for i in x2]
y2 = [math.log10(pow(10,i)) for i in x2]
fig = figure(y_axis_type =  log )
fig.circle(x2, y2,size = 5, color =  blue , legend =  blue circle )
fig.pne(x2,y4, pne_width = 2, pne_color =  red , legend =  red pne )
fig.legend.location =  top_left 
fig.legend.title =  Legend Title 
fig.legend.title_text_font =  Arial 
fig.legend.title_text_font_size =  20pt
