Interesting project, horrible presentation.<p>The colour gradient on the graph is confusing - does green mean happy, blue unhappy, and the movie changes tone over time? Axes of the graph are not labeled, what are we looking at? But, those concerns are secondary.<p>Bar graph seems a poor choice here, given the nature of the data. Given that there doesn't seem to be any correlation with time, the order of phrases doesn't seem important -- you could forgo the linear presentation, and display the distribution of the data instead.<p>For example, you could bucket the sentiment values (-3 to -2, -2 to -1, etc) and use a histogram to show the counts in each bucket. This would enable you to compare different movies (one histogram per movie).
