FAQ
Line chart FAQs
How do I create a multi-series comparison graph online?
Open the tool, describe your chart or start blank, then add values for each series. Toggle legend and dots, choose linear or monotone lines, and export or embed when ready.
Can I compare more than two lines?
Yes. Add as many series as you need and use distinct colors or stroke patterns to keep the chart readable. The legend maps each series clearly.
What’s the difference between linear and monotone lines?
Linear connects points with straight segments. Monotone smooths curves while preserving overall trends. Use monotone for gradual patterns and linear for abrupt changes or precise step‑like behavior.
How do I control the legend and markers?
Enable Show legend and choose Top, Left, Right, or Bottom. Toggle Show dots to highlight point values or hide them for cleaner trend views.
Can AI set up the line chart for me?
Yes. Describe your multi‑series comparison, including series names, smoothing preference, legend position, and whether to show dots. AI builds a complete configuration with clear labels and styles.
What export options are available?
Download PNG or SVG for high‑quality visuals, copy a share link for quick reviews, or embed the chart on your site so updates stay in sync.
How many points per series can I add?
You can add as many points as your dataset requires. Use the + Add point control and edit Name and Value cells to manage entries quickly.
