Overview
A line chart plots data points along a continuous axis, almost always time, and connects them so the shape of the trend is obvious: rising, falling, flat or volatile. It is the default choice whenever the question is 'how is this changing?', from weekly active users to monthly revenue to a stock price.
What makes the line chart powerful is continuity. Because the x-axis is continuous, the slope between points carries meaning, a steep climb reads as fast growth, a plateau as stalling. That is also its boundary: a line chart only makes sense when the x-axis is ordered and continuous. For separate, unrelated categories, a bar chart is the right tool.
Reochart draws the line on from left to right as it animates, so the trend unfolds like a story rather than appearing all at once, which is exactly what stops the scroll on LinkedIn or X. You can plot a single line, or up to five together to compare plans, segments or cohorts on one chart, each with its own colour and a legend. Export as MP4, GIF, PNG or SVG, with your brand colours on Pro.
How it works
Each data point is positioned by its x-value (the time period) and its y-value (the metric), then consecutive points are joined. The eye reads the line's direction and steepness as the rate of change, so the gaps between points should represent equal time intervals or the slope misleads.
With several series, each line gets its own colour and a legend entry. Keep it to a handful, beyond about five lines they start to cross and tangle, and the comparison is lost.

Line chart vs the alternatives.
| Chart type | Best for | Avoid when |
|---|---|---|
| Line | A trend over continuous time | Separate, unrelated categories |
| Area | A single trend you want to feel bigger | Comparing several precise series |
| Bar / column | Comparing values across categories | A continuous time trend |
| Multi-line | Comparing 2-5 series over time | More than ~5 series (they tangle) |
Your data
One row per time period: a label and a value (add more columns for extra series). Paste from a sheet or import a CSV. 6 to 12 points reads best.
| Period | Value |
|---|---|
| Jan | 12 |
| Feb | 19 |
| Mar | 27 |
| Apr | 34 |

Best practices
Watch out
Lines imply continuity. Using them for unrelated categories suggests a sequence that is not real, use bars.
Past five series the chart becomes spaghetti. Split into small multiples or highlight one line at a time.
If points are not evenly spaced in time, the slope lies. Keep intervals consistent.
A two-point line says little. Show enough history for the trend to mean something.
Why Reochart
FAQ
A chart that plots data points over a continuous axis (usually time) and joins them with a line, so the trend is obvious at a glance.
Use a line chart when the x-axis is continuous time and you care about the trend. Use a bar chart to compare distinct, unrelated categories.
Yes, up to five series on one chart, each with its own colour and a legend, ideal for comparing plans, segments or cohorts.
A line is cleaner for comparing series precisely; an area chart fills under a single line to make growth feel bigger.
Six to twelve points usually reads best. Too few and a bar chart is clearer; too many and labels crowd.
Yes. Charts animate by default, and you can export the animation as an MP4 or GIF, or grab a static PNG or SVG if you prefer.
Yes. Pro exports a crisp, scalable SVG vector, alongside MP4, GIF and PNG. Every export renders at 1080p.
Paste your period-and-value rows from Excel or Google Sheets, or import a CSV (Pro). Extra columns become extra lines.
Yes. The free plan lets you make every chart type and export an animated MP4 with a small watermark, no card needed. Pro removes the watermark and adds GIF and SVG, your brand colours and logo, longer videos and CSV import.
