Series

A series is the starting point for almost everything in DataJot. Before adding measures, decide what you want to track.

If you want a ready-made starting point, browse the series template list.

Choose a good series name

A good series name should be clear. “Living Room Temperature” is more useful than “Temperature”, especially if you later add “Bedroom Temperature” or “Outdoor Temperature”.

For a counter, choose a name that describes the tracked action: “Coffee”, “Workout Sets”, or “Cigarettes”. For a measured value, add context: “Weight”, “Bathroom Humidity”, or “Rice Stock”.

Create a series

The series form starts with general information: name, description, category, icon, and color.

The name is required. DataJot cannot save the series while the name is empty. The description is optional, but it can help explain what the series represents.

The data section defines how the series behaves. You can choose a unit, aggregation method, display precision, chart type, and default view.

The chart section lets you associate a visualization configuration. You can skip it at first and come back later.

Create from a template

Templates help you create a coherent series faster.

If you choose a temperature template, DataJot can prefill the name, description, icon, color, chart type, and aggregation method. If the template includes a unit or visualization configuration, DataJot reuses an existing one when possible, otherwise it creates it.

A template is a starting point, not a constraint. You can still adapt the series to your own use.

Series templates visible on the site provide examples of tracking setups you can adapt. You can find them in the template library.

Template types

DataJot can rely on several types of templates.

A series template describes the tracking setup to create: name, description, icon, color, chart type, and aggregation method.

A unit template describes how values are expressed. For example, a temperature series can rely on a unit with the right sub-unit. You can check the unit list to see units documented on the site.

A visualization template describes how to read the series: visible statistics, thresholds, colors, or Y-axis bounds. It helps produce a coherent chart without configuring every detail manually.

These templates can be combined. A series created from a template can therefore reuse a unit and a visualization configuration when the template provides them.

Understand aggregation

Aggregation defines how DataJot summarizes several measures in the same period.

For temperature, average is often useful because it summarizes the general evolution. For a coffee counter, sum is more logical because you want the total. For a stock value, last value can be more useful because it represents the latest known state.

Available methods:

• Average: calculates the average value.
• Sum: adds values together.
• Last value: uses the latest chronological measure.
• Minimum: uses the smallest value.
• Maximum: uses the largest value.

This choice influences charts and statistics. If a chart does not tell the story you expect, check the aggregation method first.

Choose the default view

A series can open directly on the chart or on the measure list.

The chart is useful for trends. The measure list is better if you often correct values or use DataJot as a numeric log.

Edit or delete a series

You can edit a series from its detail screen. This is where you adjust its name, category, unit, chart, or visualization.

Deleting a series also deletes all its measures. If you only want to start over without losing the series structure, use the action that deletes all measures from the series instead.
