Line chart
A line chart is a graph that connects data points with straight lines to show change over time. In Honors Journalism, you use it to present trends clearly in data stories and infographics.
What is line chart?
A line chart in Honors Journalism is a visual for showing how a number changes across time or another ordered sequence. It places data points on a graph and connects them with straight line segments so readers can spot rises, drops, and steady patterns fast.
That makes it one of the most useful chart types in data journalism, especially when your story depends on change over days, months, years, or other intervals. If you are building an infographic about voter turnout, weather, school enrollment, or sports performance, a line chart can show the shape of the trend without making the reader read a table full of numbers.
The x-axis usually shows time or another ordered category, and the y-axis shows the value being measured. Each marker represents one data point, and the line between markers lets the audience see the direction of the data at a glance. In journalism, that visual path matters because readers are often scanning quickly, not studying the graphic for minutes.
A line chart works best with continuous data, meaning the values follow one another in a sequence where the space between points matters. That is why it is better for trends over time than for one-time category comparisons. If you were charting monthly website traffic, for example, the line shows whether audience interest is climbing, flattening, or dipping, which is easier to read than a long list of monthly figures.
Journalists also use multiple line charts on the same graph to compare datasets, like male and female readership, two news sources, or different years. The trick is keeping the chart clean enough that the comparison stays readable. Good labels, a clear scale, and a simple color choice make the chart feel like reporting, not decoration.
A weak line chart can mislead if the scale is stretched or compressed in a way that exaggerates change. In Honors Journalism, that means you have to read the graphic critically and also make it honestly when you are the one designing it.
Why line chart matters in Honors Journalism
Line charts show up anytime journalism needs to turn raw numbers into a story readers can see in seconds. They are a core tool in data visualization and infographics because they make change visible, which is often the whole point of a data-driven article.
This matters when you are choosing the right chart for the job. A line chart is not the best pick for comparing unrelated categories, but it is strong when the assignment asks you to show a trend, a rise and fall, or a pattern over time. That choice affects how convincing and readable your visual story feels.
It also trains you to think like a reporter. You are not just placing numbers on a graph, you are deciding what the audience should notice first, how the scale frames the message, and whether the visual stays accurate. That connects directly to media ethics and fact-checking, because a misleading chart can distort the story even if every data point is technically correct.

Data Points
A line chart is built from data points, so you have to know what each marker stands for before you can read the trend. In journalism, those points might be monthly page views, survey responses, or yearly totals. If the data points are unclear or missing labels, the line can still look polished while telling a confusing story.
Bar Chart
Bar charts and line charts often show different kinds of information. A bar chart is better for comparing separate categories, while a line chart is better for showing change over time. In an infographic, choosing the wrong one can make the message feel flat or harder to follow.
Scatter Plot
A scatter plot also uses plotted points, but it focuses on relationships between two variables instead of a time trend. A line chart connects points in order, while a scatter plot usually leaves them unconnected so the viewer can study spread and correlation. That difference matters when you are matching a chart type to the story.
Data Storytelling
Data storytelling is the larger skill behind using a line chart well. The chart should support the reporting angle, not replace it. In Honors Journalism, you use the line chart to make a trend obvious, then write the caption, headline, or article text so the audience knows what the pattern means.
Is line chart on the Honors Journalism exam?
A quiz question might ask you to identify the best chart for a time-based trend, or to explain what the shape of a line chart suggests about the data. In a class infographic project, you may need to build one, label the axes, and choose whether one line or multiple lines best fits the story. You could also be asked to critique a chart that uses a misleading scale or makes a trend look steeper than it really is. When you read one, focus on the direction of the line, the spacing of the axes, and what each data point represents.
Line chart vs Bar Chart
People mix these up because both compare data visually, but they do different jobs. A bar chart compares categories side by side, while a line chart shows movement across time or another ordered sequence. In journalism, that difference changes the story the graphic tells.
Key things to remember about line chart
A line chart in Honors Journalism shows change over time by connecting data points with straight lines.
The x-axis usually holds time or another ordered sequence, while the y-axis shows the measured value.
Line charts are strongest when you want readers to see a trend fast, especially in an infographic or data story.
Multiple lines can compare different datasets, but the chart still has to stay clean and easy to read.
A misleading scale can distort the story, so reading and building line charts both require accuracy.
Frequently asked questions about line chart
What is a line chart in Honors Journalism?
A line chart is a graph that connects data points to show how something changes over time. In Honors Journalism, it is often used in data stories and infographics because readers can spot trends quickly.
When should you use a line chart instead of a bar chart?
Use a line chart when the story is about change across time or a sequence, like monthly website traffic or yearly attendance. Use a bar chart when you want to compare separate categories, like different news sections or survey responses.
What do the axes mean on a line chart?
The x-axis usually shows time, dates, or another ordered set of categories. The y-axis shows the measured amount, such as counts, percentages, or ratings. Reading both axes correctly is how you understand what the line is saying.
How can a line chart be misleading?
A line chart can distort the story if the scale is manipulated or if the data points are missing context. A very tight scale can make a small change look dramatic, while a wide scale can hide a real trend. In journalism, that is why axis labels and scale choices matter.
