What is a slope chart maker?

A slope chart maker lets you create a chart with two vertical axes connected by sloped lines, one per item, showing how each value changed between two points. AECharts lets you paste data, customize colors and styling, and export and use in PowerPoint or Google Slides.

What data do I need for a slope chart?

For each item, you need a starting value and an ending value. AECharts draws a line connecting the two and angles it to show increase, decrease, or no change.

Can I import data from Excel or Google Sheets?

Yes. Copy your before/after data and paste it directly into the editor. One row per item, with a start value and an end value.

What export formats are available?

Every chart exports ready to use in PowerPoint or Google Slides, or as an image for reports.

Can I customize the colors?

Yes. Lines can be colored by item, or by whether they increased or decreased. You can also adjust fonts, background color, and label styles to match your brand.

What is a slope chart used for?

Slope charts are used to show change between two points, year-over-year revenue by segment, before/after a campaign or intervention, or ranking shifts between two periods. They're a compact alternative to two side-by-side bar charts.

What is the difference between a slope chart and a line chart?

A line chart typically shows many points across a continuous time series. A slope chart is built for exactly two points, it isolates the change itself, which makes direction and magnitude easier to compare across many items at once.

Do I need design skills?

No. Templates are professionally designed, paste your data and adjust colors if needed. Most users create their first slope chart in under a minute.

Is there a free plan?

Yes. AECharts is free to start, exports on the free plan include a watermark. The paid plan removes it, starting at $12/month billed annually. No credit card required to start.

Can I use a slope chart in a presentation?

Yes. Charts export ready to drop directly into PowerPoint and Google Slides. Slope charts work well in QBRs, annual reviews, and any deck comparing this period to last.

When to Use a Slope Chart

Slope charts work best when you have exactly two points in time and want the change itself, not the full trend, to be the focus.

Year-over-Year Comparison: Show revenue, headcount, or margin by segment for last year versus this year in one compact view.
Before/After Campaign Results: Show a metric before and after a marketing campaign, pricing change, or product launch.
Ranking Shifts: Show how competitors, products, or regions changed rank between two periods.
Pre/Post Intervention Analysis: Show the effect of an operational or policy change by comparing values before and after.
Portfolio Company Comparison: Show performance change across portfolio companies between two reporting periods.
Survey Score Change: Show how satisfaction, NPS, or engagement scores moved between two survey waves.

Slope Chart vs Line Chart

Both use connected lines, but they're built for different amounts of data.

Slope Chart

Best for: Exactly two time points, many items to compare.
Strength: Isolates the change itself, direction and magnitude are immediately visible.
Use when: Year-over-year, before/after, ranking shifts.

Line Chart

Best for: A continuous trend across many time points.
Strength: Shows the full shape of change over time, not just endpoints.
Use when: Monthly, quarterly, or multi-year trends.

AECharts supports both. Switch between chart types to find the right format for your data.
