Matrix Stats Aggregation Usageedit
Fluent DSL exampleedit
s => s
.Aggregations(a => a
.MatrixStats("matrixstats", ms => ms
.Meta(m => m
.Add("foo", "bar")
)
.Fields(fs => fs
.Field(p => p.NumberOfCommits)
.Field(p => p.NumberOfContributors)
)
.Missing(m => m
.Add(Field<Project>(p => p.NumberOfCommits), 0)
.Add(Field<Project>(p => p.NumberOfContributors), 1)
)
.Mode(MatrixStatsMode.Median)
)
)
Object Initializer syntax exampleedit
new SearchRequest<Project>
{
Aggregations = new MatrixStatsAggregation("matrixstats", Field<Project>(p => p.NumberOfCommits))
{
Meta = new Dictionary<string, object>
{
{ "foo", "bar" }
},
Missing = new Dictionary<Field, double>
{
{ "numberOfCommits", 0.0 },
{ "numberOfContributors", 1.0 },
},
Mode = MatrixStatsMode.Median,
Fields = Field<Project>(p => p.NumberOfCommits).And("numberOfContributors")
}
}

Handling Responsesedit
response.ShouldBeValid();
var matrix = response.Aggs.MatrixStats("matrixstats");
matrix.Should().NotBeNull();
matrix.Fields.Should().NotBeNull().And.HaveCount(2);
AssertField(matrix, "numberOfCommits");
AssertField(matrix, "numberOfContributors");
