ODI/Tests selector

[lprsd]

• Separate navigation for ODIs and Tests can create an additional click away from looking at the charts. We should instead have a button on the top right corner of each page to choose either ODI or Tests as follows.

To achieve this seamlessly, following can be done:

• Main controller watches for change to this model and changes the folder path (to chose test data or ODI data)
• Each controller to define function plot_graph which will be called upon the change of the model to re-render.
