I've made a new test with PageOneX about the different corruption cases in Spain an its coverage in national newspapers:
Each topic (color) is one political party's corruption case. It's a good example to show how each newspaper has its preferences about which cases to cover (and which don't), and how they set their agendas.
I've used one technique that I hadn't used before. Once I had coded all the newspapers I went to edit the thread and selected only one newspaper, but remembering always to check at the bottom the box "Keep all highlighted areas that you have done, even which is related to deleted images". IMPORTANT: If you don't do so, you'll lose all your highlighted areas. Be aware! Once I had the image of one newspaper alone, I edited the thread again and added all the other newspapers again, remembering to check "Keep all highlighted areas ...". I'll have to make this process easier, but for now it works!
That's a good way to display only one newspaper and calculate the percentages, but not lose all the other areas.
Looking forward to further develop the tool this February!
