Finta supports four chart types. Each reads from a single Notion database and measures a Value field, with type-specific options for grouping and time.
Finta stores expenses as negative amounts and income as positive amounts. Keep this in mind when choosing a value field — and use a filter to separate spending from income when you want a clean breakdown.

Metric

A single headline number — for example, total spend this month.
OptionDescription
ValueThe field to measure.
CalculationSum, Average, Min, or Max.
Date field & GranularityOptional. Bucket the metric by day, week, month, quarter, or year.
Compare to previous periodShow the change versus the prior period, with an up/down indicator.
Show increase as positiveControls whether an increase is styled as good (green) or bad (red) — useful for spending vs. revenue.

Bar

Compare a value across categories or over time.
OptionDescription
ValueThe field to measure.
X-AxisThe field to plot along the bottom (a category, or a date field for a time series).
CalculationHow to aggregate values within each bar.
Group ByOptional. Split each bar into a series by a second field.
StackedWhen grouping, stack the series into a single bar instead of placing them side by side.

Line

Track one or more series over time.
OptionDescription
ValueThe field to measure.
X-AxisUsually a date field; also supports categorical axes.
CalculationHow to aggregate values at each point.
Group ByOptional. Plot a separate line per value of this field.

Donut

Show how a total breaks down across categories.
OptionDescription
ValueThe field to measure.
Group ByThe field that defines each slice (for example, Category).
Slice minimumSlices smaller than this share of the total are combined into an Other slice.
Donut slices are sized by the absolute magnitude of each category’s total, and the center shows the absolute combined total, so a spending breakdown reads naturally even though Finta stores expenses as negative numbers. Filter out income first for the cleanest breakdown.
