Raw data time series

[ChloeRN]

We want to create a plot that shows the raw data in each location over time. "Raw data" here refers to the data as stored in the NI database. "Location" represents the smallest spatial units available (or the spatial units used for plotting on the NI webpage). As a general rule, uncertainty in the data should be visible in the plot. Two representations of the plot may be relevant:

• [ ] Plot showing data time series in all locations overlaid
• [ ] Separate plots showing data time series for a specific location, including reference value for that location
