Track trends and changes over time with our easy online tool.
Upload an Excel file with the first column as categories (X-axis) and the second column as values.
Great question. Think of line graphs as the storytellers of the data world. They are the absolute best choice when you want to show trends or how something changes over a period of time—like stock prices going up, temperatures dropping, or website traffic growing month by month. If you're trying to compare distinct categories (like apples vs. oranges) without a time element, a bar chart is usually your best bet.
Technically, you can add as many as you like! Our Multi-Line Graph Maker supports multiple series. However, for the sake of your readers, we usually recommend sticking to 3-5 lines max. Any more than that and your chart can start to look like a plate of spaghetti, making it hard to see which line is which. If you have tons of data series, consider creating a few separate charts instead.
We've built that option right in! In the Style tab, look for the "Line Style" dropdown. You can switch between "Straight" (for precise, point-to-point connections) and "Smooth" (which adds a nice curve to the line). Smooth lines are often more visually appealing and help emphasize the overall flow of the trend.
Yes! We know typing in data manually can be a pain. In the Data tab, simply click "Upload Excel File" or grab our template first to see how to format it. Just make sure your first column contains your time intervals (like months or years) and the subsequent columns have your values. The chart will update instantly.
100%. We take privacy seriously. All the chart generation happens directly in your web browser. Your data is never uploaded to our servers, stored in a database, or seen by anyone else. You can safely create charts for sensitive business or personal data with complete peace of mind.
