How to Analyze Plotted Functions? Plotting functions is not as technical or difficult as the students believe it to be. However, the real challenge lies when it comes to analyzing plotted functions. A lot of students find it difficult to reach to conclusions and identify the trends in it. These three simple steps will help you analyze a plot and make deductions about it. Step 1: Comprehending the Data - The first step is to comprehend the data by gaining a basic understanding of the data. Step 2: Interpretation of the Data - While interpreting the data we have to identify the obstacles, examine the climax as well as the resolution of the plot. It is the part where we look at different parts of the story. Step 3: Conclusions - The final step is to conclude and identify the trends of data by looking at the plot.
