End Value — shows the final value only (no name) at each line tip once animation completes.
X Labels / Y Labels — font size for the date and value axis labels.
Legend — the floating series name list to the right of the chart. Hidden automatically when Live Labels is on.
Chart

Aspect ratio — the canvas shape: Square (Instagram), Portrait (TikTok), Landscape (YouTube), etc.
Line size — thickness of the animated lines.
Line style — Rounded glides through points like a rollercoaster; Sharp uses straight segments.

Endpoint — a dot at the current tip of each line.
Data Points — dots at every data point along each line.
Gridlines — horizontal reference lines behind the chart.

Colors
›
Background — the canvas fill color (default white; try black for a dark look).
Text colors — individually control the color of the title, subtitle, timestamp, and axis labels.
Series colors — once data is loaded, each line gets a color swatch you can click to change.
Tip: dark backgrounds with bright line colors tend to look great on social media.
Events
›
Events — highlight a date range on the chart with a shaded band and a label.
Great for marking recessions, elections, product launches, or any period you want to call out.
Each event needs a label, a start date, and an end date (DD/MM/YYYY format).
Audio
›
Audio — add background music to your exported video.
Pick a track, set the volume, and drag the Start slider to choose which part of the song plays.
Hit Preview to hear it before recording. Music is mixed directly into the exported file.
How Pulls Work
Each API key includes 25 free pulls per day, resetting every 24 hours. Heartbeat's smart caching means one pull can power dozens of charts — most users will never come close to their daily limit.

Share Price
1 pull per ticker — covers all date ranges and intervals. Cached for your session, so pulling the same ticker again won't cost you unless you close or refresh the tab.

Financials
1 pull per financial statement. Pulling any metric from a statement unlocks the entire statement instantly.

1 pull → entire Income Statement
1 pull → entire Balance Sheet
1 pull → entire Cash Flow Statement

All financial data is cached in your browser for 7 days — even after closing or refreshing.

Example: Pull Revenue, Total Assets, and Free Cash Flow — just 3 pulls. Every metric across all three statements is now yours to chart — unlimited, for 7 days before needing to pull again.

Crypto & Forex pulls follow the same structure and share your daily 25 pull limit. You can track how many pulls you've used in the daily counter in the Stocks and Crypto tabs.
