Value

The Value component accepts a query and displays a formatted value inline in text.

By default, Value will display the value from the first row of the first column of the referenced data.

<Value data={query_name} /> <!-- First row from the first column -->

Specifying Rows and Columns

Optionally supply a column and/or a row argument to display other values from data.

<!-- Show the **7th row** from column_name -->

<Value 
    data={query_name}
    column=column_name 
    row=6
/>

Example

Markdown:

The most recent month of data began <Value data={monthly_orders} />,
when there were <Value data={monthly_orders} column=orders/> orders.

Results:

Adding a Placeholder

Override errors with the optional placeholder argument. This is useful for drafting reports before writing your queries.

<Value placeholder="sales last year"/>

Sales in the last fiscal year were [sales last year]Placeholder: no data currently referenced., a change of [X%]Placeholder: no data currently referenced. vs. the prior year.

Formatting Values

Evidence supports a variety of formats - see value formatting and the fmt prop below for more info.

Aggregated Values

Values support basic aggregations such as, min, max, median, sum, avg

<Value data={orders} column="sales" agg="avg" fmt="usd0" />

Customize Color Values

<Value data={orders} column="sales" agg="avg" fmt="usd0" color="#85BB65" />

<Value data={orders} column="sales" agg="avg" fmt="usd0" color="blue" />

<Value data={orders} column="sales" agg="avg" fmt="usd0" color="rgb(200,5,200)" />

Red Negative Values

If the value is negative, the font color will automatically change to red, overriding any color specified by the color prop.

<Value data={NegativeSales} column="max_sales" agg="avg" fmt="usd0" redNegatives="true" />
