# logarithmicBins() function

-   Flux 0.19.0+
-   View InfluxDB support

`logarithmicBins()` generates a list of exponentially separated float values.

Use `linearBins()` to generate bin bounds for `histogram()`.

##### Function type signature

```js
(count: int, factor: float, start: float, ?infinity: bool) => [float]
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### start

(Required) First value to return in the list.

### factor

(Required) Multiplier to apply to subsequent values.

### count

(Required) Number of values to return.

### infinity

Include an infinite value at the end of the list. Default is `true`.

## Examples

### Generate a list of exponentially increasing values

```js
logarithmicBins(
    start: 1.0,
    factor: 2.0,
    count: 10,
    infinity: true,
)// Returns [1, 2, 4, 8, 16, 32, 64, 128, 256, 512, +Inf]

```
