How do I make a line graph with multiple lines?
Add one column per line next to the labels column — for example Week, Visitors, Sign-ups. Each column becomes its own coloured line.
What if some values are missing?
Leave the cell empty and the line will join the points either side of the gap.
Line or area chart?
Line charts are best for comparing trends; area charts emphasise volume over time.
Can I label the axes?
Yes — fill in the X-axis and Y-axis labels, such as “Month” and “Revenue ($)”.
Can I paste data from Excel or Google Sheets?
Yes. Select the cells (including the header row), copy, and paste into the data box — the columns are detected automatically. You can also import a .csv file.
Is my data uploaded?
No. The chart is drawn in your browser and your numbers never leave your device.
