Struct DagChartConfig 

pub struct DagChartConfig {
    pub abbreviate: bool,
    pub show_aggregate: bool,
}

Render configuration specific to DagCharts.

Example

let dagchart_config = DagChartConfig {
    abbreviate: true,
    show_aggregate: true,
    ..DagChartConfig::default()
};

Fields

abbreviate: bool

Whether to abbreviate the dimensional values in the rendering or not. Use this option when the dimensions have long std::fmt::Display forms. Abbreviation is attempted irrespective of the width_hint.

Notice, abbreviation is performed on values only, and not on the column headers. Moreover, the abbreviation is bounded by the column header width. If you want shorter abbreviations, be sure to shorten the headers as well!

Default: false.

show_aggregate: bool

Whether to show the aggregated result for the non-primary dimension(s) of the dataset. Notice, this is different from show_aggregate in the root Render configuration (which shows the primary dimension).

The aggregate always represents the matched columns from the primary towards the non-primary. Consequently, the result at each level shows the aggregate across the previous level - that is, the aggregates “cascade”.

For example, consider the following Dataset.

r#"
A (primary) | B  | C  | value
a1          | b1 | c1 | 1
a1          | b2 | c1 | 2
a1          | b2 | c2 | 3"#

Then, the aggregate computation for each level is as follows:

r#"
Dimensional Combinations | Show Aggregate
(a1,)                    | aggregate([1, 2, 3])
(a1, b1)                 | aggregate([1])
(a1, b2)                 | aggregate([2, 3])
(a1, b1, c1)             | aggregate([1])
(a1, b2, c1)             | aggregate([2])
(a1, b2, c2)             | aggregate([3])"#

In flat, the above dataset as Aggregate::Sum will render as follows:

// Output (modified for alignment)
// Observe the cascade (ex: `b2 [5] = c1 [2] + c2 [3]`).
r#"
C  Sum   B  Sum   A  Sum
c1 [1] - b1 [1] ┐
c1 [2] - b2 [5] - a1 [6]
c2 [3] ┘        ┘"#

Default: false.
