The application shall have two modes:
- Estimates, showing estimated months left of a selected stock, for chosen organization units.
- Time trend, showing time trend of stock for a single organization unit.
The user can choose between the two modes described above.
- Default min/max boundaries can be set by an administrator (administrator view in mockup).
- The user can specify their own desired min/max boundaries as well (user view in mockups).
- If the administrator has not set a default min/max boundary, there is no default min/max boundary in the plot.
- The user can specify one stock type, and multiple organization units.
- Show current estimates as columns in a column diagram.
- Columns outside the specified min/max boundaries will be highlighted.
- Estimates are calculated based on average consumption over the last 3 months, and current stock levels ((current stock) / (average consumption) = estimated months left).
- Default min/max boundaries are shared by all organization units.
For "Time trend":
- The user can select an organization unit, and a stock type.
- Show time trend(months) of available stock as a graph.
- The min/max boundaries are shown as lines in the graph.
- The user can choose the time period they wish to see the time trend for (by default the last 6 months).
- Default min/max boundaries are associated with a specific organization unit and stock type.
Changes from the initial requirements:
- Administrator has two min/max inputs, one for each mode.
- The administrator can create and save queries.
- The user can pick queries created by an administrator to generate plots quickly.
- The query options used by the administrator is also accessible to the user, but hidden behind a "Show advanced options" button.
- "Stock usage" and "Stock availability" are selected separately through separate dropdown menus. "Stock usage" is not used for the "timetrend"-mode.
- The administrator can delete old query presets.
- The administrator can see a preview of the results of their query before saving it.
- The "estimates"-mode has a "from"-date. The average use is calculated based on the period from the chosen date up to the current date.

We have chosen React JS, because of the view focused framework. We also feel that the group as a whole has more experience with React.
We used Create-React-App to set up the initial app and build our project.We have used basic CSS functionality, but have not used any extra front end frameworks as we felt it would unnecessarily complicate the code.
Highcharts is a dynamic plotting tool. We used it to create the plots for our project since we found it easy to use and it quickly gave nice looking plots.
We used React-Select because we needed a dropdown-menu with search function, and the ability to select multiple items.
We used Semantic UI for improving the user interface.
We originally used MIT licensing, that the components React-Select, Semantic-UI and React JS had.
Sadly, late in the project we discovered that Highcharts is not compatible with any open source licenses , therefore we need to use CC(creative commons) Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0). This means our app cannot be used for commercial purposes.
