6NVD3 is an attempt to build re-usable charts and chart components

18 A linePlusBarChart Chart is a type of chart which displays information 

19 as a series of data points connected by straight line segments 

20 and with some series with rectangular bars with lengths proportional 

21 to the values that they represent. 

22 

23 Python example:: 

24 

25 from nvd3 import linePlusBarChart 

26 chart = linePlusBarChart(name="linePlusBarChart", 

27 width=500, height=400, x_axis_format="%d %b %Y", 

28 x_is_date=True, focus_enable=True, 

29 yaxis2_format="function(d) { return d3.format(',0.3f')(d) }") 

30 

31 xdata = [1338501600000, 1345501600000, 1353501600000] 

32 ydata = [6, 5, 1] 

33 y2data = [0.002, 0.003, 0.004] 

34 

35 extra_serie = {"tooltip": {"y_start": "There are ", "y_end": " calls"}, 

36 "date_format": "%d %b %Y %H:%S" } 

37 chart.add_serie(name="Serie 1", y=ydata, x=xdata, extra=extra_serie, 

38 bar=True) 

39 

40 extra_serie = {"tooltip": {"y_start": "There are ", "y_end": " min"}} 

41 chart.add_serie(name="Serie 2", y=y2data, x=xdata, extra=extra_serie) 

42 chart.buildhtml() 

43 print(chart.content) 

44 

45 Note that in case you have two data serie with extreme different numbers, 

46 that you would like to format in different ways, 

47 you can pass a keyword *yaxis1_format* or *yaxis2_format* when 

48 creating the graph. 

49 

50 In the example above the graph created presents the values of the second 

51 data series with three digits right of the decimal point.
