# Plot Frame
The plot frame function.
Display an [Image](/reference/images/image) on the @boardname@'s [LED screen](/device/screen)
### JavaScript
```sig
export function plotFrame(_this: micro_bit.Image, index: number)
```
### Parameters
* index - [Number](/reference/types/number); which frame of the image to display
### Difference from `plot image`
The `plot frame` function takes the index of the frame (if there are two frames, then the possible indices are 0 and 1), whereas `plot image` accepts an offset (if there are two frames, the offset would range between 0 and 9).
### Example
```blocks
let img = images.createImage(`
# . . . # # . . . #
. # . # . . # # # .
. . # . . . # # # .
. # . # . . # # # .
# . . . # # . . . #
`)
img.plotFrame(1)
```
