I'm trying to make an XYLine with the Google Chart API via the not-so-well-documented GChartWrapper
libraries.
Here's a portion of the code that is supposed to generate the graph:
data = []
traffic_max = 0
date_minmax = []
#I have a number of timestamped readings in two series
for site in sites:
site_data = get_datapoints_for(site)
date_values = [datetime_to_unix(item.timestamp) for item in site_data]
date_minmax = minmax(date_minmax + date_values) #get min and max values for
#scaling
traffic_values = [item.traffic for item in site_data]
traffic_max = max(traffic_max, *traffic_values) #just get maximum for readings
#build graph
data.append(date_values)
data.append(traffic_values)
#add leeway to axes
date_minmax[0] -= 500
date_minmax[1] += 500
traffic_max /= 0.9
#build graph
chart = LineXY(data)
chart.legend(*sites)
chart.color("green", "red")
chart.size(600,400)
chart.scale(date_minmax[0], date_minmax[1], 0, traffic_max)
chart.axes.type("xy")
chart.axes.range(0, *date_minmax)
chart.axes.range(1, 0, traffic_max)
chart_url = chart.url
However, this is what I get:
Question: What happened to the red series?
For your convenience, here is data
after some pretty print love:

Here is the list of parameters generated by the wrapper, also after some pretty print love:
