Line Graph for Temperature Log — Thermal Telemetry & Sensor Time-Series
A temperature log line graph plots sequential thermometer or thermocouple readings $T(t_i)$ over time to monitor thermal stability, ramp rates ($dT/dt$), and excursion bounds.
Tip: Paste Excel or Google Sheets rows (Ctrl+V / ⌘V) directly into any cell.

Thermal range: Delta_T = T_max - T_min. Mean Kinetic Temperature approximation or arithmetic mean: T_mean = (1/n) * sum(T_i). Ramp rate: (T_i - T_{i-1}) / Delta_t.
Chart Design & Use-Case Tips
- 01Thermal range: Delta_T = T_max - T_min. Mean Kinetic Temperature approximation or arithmetic mean: T_mean = (1/n) * sum(T_i). Ramp rate: (T_i - T_{i-1}) / Delta_t.
- 02Check Min, Max, Mean, and Std Dev in the live statistics strip to verify whether the thermal profile stayed within specification limits.
- 03Paste CSV data loggers (e.g., Fluke, Testo, or Arduino/ESP32 serial dumps) directly into the CSV/TSV Workbench.
- 04Supports both positive and negative temperatures (°C, °F, or Kelvin).
Frequently Asked Questions
Does the chart handle negative sub-zero freezer temperatures?+
Yes, negative values (such as -18.5 °C or -80 °C ultra-low freezer logs) plot accurately with automatic y-axis scaling.
How can I monitor two temperature probes simultaneously?+
Switch to the Multi-Line Graph Maker to plot Ambient Temperature in Series A and Core/Chamber Temperature in Series B.
Can I print this log for cold-chain or HACCP compliance records?+
Yes, click 'Print / Save PDF' or 'Export 300-DPI PNG' to archive a timestamped visual record with summary statistics.
