Scatter Plot Graphs leading to Line Graph A scatterplot is a graph consisting of isolated points, with each dot corresponding to a data point. To make a line graph, we begin with a scatterplot and join the adjacent points with straight-line segments.Example:These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Once you connect the dots, it makes a line graph and should look like this:2. Bar Graphs a. The bars should not touch in a normal bar
