I'm struggling to find a suitable graph to represent the sample of the data below. I would like to see the data in a bar chart or something similar where i can compare both methods side by side. Can anyone help please?

Thanks for this. I am trying to compare 4 different methods of testing. Sorry! I know my code only showing two methods. The issue is as the number of rows increase the Y axis's get crowded and make the graph looks hard to understand. It doesn't have to be bar chart can use something else as long as i have away of showing the difference. May be something like a facets. Thanks for your help

Many Thanks for your help! The bar chart looks better in terms of showing the differences clearly. Is there away to get facets with a bar chart of each method, and with the Y axis's show as scale but not representing the value of each test. Thanks a lot
