Line Chart Maker
Enter your X and Y data below to generate an interactive line chart. You can also paste CSV or spreadsheet data into either input.
How to Use the Line Chart Maker
Enter your X values in the left input and Y values in the right input, with values separated by commas, spaces, or newlines. Both lists must have the same number of values. Choose between solid, dash, or dot line styles, and optionally enable smooth spline interpolation or fill the area under the line. Use the camera icon in the chart toolbar to download your line chart as a PNG image.
What Is a Line Chart?
A line chart connects data points with straight or curved lines to show trends and changes over a continuous interval. Line charts are commonly used to display time series data — such as stock prices, temperature readings, or website traffic over time. The X axis typically represents time or a sequential variable, while the Y axis represents the measured value.
