Existing graph of mirror status
Seems you couldn’t understand the above graph? Yep, this is the problem with existing design. Very hard to interpret & a layman can’t understand it. I setup few goals to overcome the drawbacks of this representation.
- Make it simple to understand,
- Represent mirror states clearly,
- Highlight bad mirrors as they are most important to identify,
- Emphasize the outliers in graph.
After working for few hours I came up with this design. It shows clear axis and various states of mirrors but I failed to represent the bad mirrors and outliers with more emphasis.
I used bubble chart to visualize the data as they represent outliers well. But it looks too much and not simple. More over it doesn’t represent zero values clearly.
Final Version 3
Finally I came up with the above simple and straight forward design. It worked well and met all the requirements.
