Frequently Asked Questions (FAQ)
Can I use this tool on smartphones or tablets?
Yes. The tool runs in your browser on smartphones and tablets as well as desktop PCs. Use it on the go whenever you need a quick chart.
Can I use the created charts for commercial purposes?
Yes. All generated charts can be used for personal and commercial projects, pitch decks, client reports, websites, and presentations at no cost.
Is my data transmitted to a server?
No. All data processing occurs locally within your browser. Values are never uploaded, transmitted, or stored on external servers.
Can I customize the chart colors?
Yes. Apply one of the 8 curated color themes or customize each line series individually using the dedicated color picker.
Can I add a horizontal target or benchmark line to the trend chart?
Yes. Enable the "Target & Reference Line" section and enter your value to overlay horizontal benchmarks, such as sales quotas or budget targets, complete with custom labels and badge indicators.
How can I make line graphs clearer for presentations?
Limit active lines to 3–5 series, use solid lines for key metrics and dashed lines for projections, and adjust axis minimum values to highlight subtle changes.
When should I use a line graph versus a bar chart?
Use line charts to emphasize changes and continuous trends over time. Use bar charts to compare discrete quantities between categories.
Can I display numbers directly on data points?
Yes. Turn on "Data Labels" to print values above, below, or centered on each point, with custom prefixes and unit suffixes.
What types of data work best with line graphs?
Monthly revenue trends, website visitor counts, conversion rate tracking, currency exchange movements, and scientific time-series measurements.
