Which Type of Chart Displays Data Values as Points Connected by Some Lines?

When it comes to visually representing data, charts are an essential tool. They allow us to analyze and understand complex information quickly and efficiently.

One type of chart that is commonly used is the line chart. But did you know that there are variations within this category? In this article, we will explore the type of chart that displays data values as points connected by lines.

The Line Chart

The line chart is a powerful visualization tool that displays data points connected by straight lines. It is an effective way to show trends over time or relationships between different variables. However, sometimes we need to display more detailed information within the chart itself.

The Scatter Plot

In cases where we want to emphasize individual data points rather than trends, we can use a scatter plot. A scatter plot displays individual data points as markers on a graph.

Each point represents a combination of two variables, such as x and y coordinates. These markers can be customized to represent different categories or values.

However, scatter plots do not connect the points with lines, which makes it difficult to identify patterns or trends in the data. This is where another type of chart comes into play.

The Line Plot

A line plot combines elements from both line charts and scatter plots. It displays individual data points as markers connected by lines. This allows us to see the relationship between each point while also observing any trends or patterns in the data.

To create a line plot, you need at least two variables: one for the x-axis and one for the y-axis. The x-axis represents one variable, such as time or distance, while the y-axis represents another variable like temperature or sales figures.

Creating a Line Plot in HTML

To create a line plot in HTML, you can use various libraries or frameworks like D3.js or Chart.js. These libraries provide comprehensive functions and customizable options to create interactive and visually appealing line plots.

Here’s a basic example of how to create a line plot using Chart.js:

<canvas id="lineChart"></canvas>
var ctx = document.getElementById('lineChart').getContext('2d');
var chart = new Chart(ctx, {
type: 'line',
data: {
labels: ['January', 'February', 'March', 'April', 'May'],
datasets: [{
label: 'Sales',
data: [120, 150, 180, 200, 220],
borderColor: 'red'

This code snippet creates a canvas element with the id “lineChart” and initializes a new Chart.js object. It specifies the chart type as “line” and provides the necessary data for both the x-axis labels and y-axis values. In this example, we are displaying sales figures over five months.

Customizing Your Line Plot

Chart libraries like Chart.js offer a wide range of customization options to make your line plot visually engaging. You can change colors, add tooltips, display legends, and much more.

To customize your line plot further, you can refer to the library’s documentation for specific functions and options. Experiment with different settings until you achieve the desired look and functionality.


The type of chart that displays data values as points connected by lines is called a line plot. It combines the individual data points of a scatter plot with the connected lines of a line chart.

Line plots are useful when you want to observe trends or patterns while still emphasizing individual data points. By using libraries like Chart.js, you can create interactive and visually engaging line plots in HTML.
