## Histogram
|
|
|
|
### Parameters
|
|
* auto_int :: Auto calculate data point interval?
|
|
* resolution :: If auto_int is enables, shoot for this many data points, rounding to
|
|
sane intervals
|
|
* interval :: Datapoint interval in elasticsearch date math format (eg 1d, 1w, 1y, 5y)
|
|
* fill :: Only applies to line charts. Level of area shading from 0-10
|
|
* linewidth :: Only applies to line charts. How thick the line should be in pixels
|
|
While the editor only exposes 0-10, this can be any numeric value.
|
|
Set to 0 and you'll get something like a scatter plot
|
|
* timezone :: This isn't totally functional yet. Currently only supports browser and utc.
|
|
browser will adjust the x-axis labels to match the timezone of the user's
|
|
browser
|
|
* spyable :: Dislay the 'eye' icon that show the last elasticsearch query
|
|
* zoomlinks :: Show the zoom links?
|
|
* bars :: Show bars in the chart
|
|
* stack :: Stack multiple queries. This generally a crappy way to represent things.
|
|
You probably should just use a line chart without stacking
|
|
* points :: Should circles at the data points on the chart
|
|
* lines :: Line chart? Sweet.
|
|
* legend :: Show the legend?
|
|
* x-axis :: Show x-axis labels and grid lines
|
|
* y-axis :: Show y-axis labels and grid lines
|
|
* interactive :: Allow drag to select time range
|
|
