|
|
|
+ ## Histogram
|
|
|
+
|
|
|
+ A bucketted time series representation of the current query or queries. Note that this
|
|
|
+ panel uses facetting. I tried to make it safe by using sequential/serial querying but,
|
|
|
+ yeah, you should know that it uses facetting. It should be pretty safe.
|
|
|
+
|
|
|
+ ### Parameters
|
|
|
+ * query :: an array of objects as such: {query: 'somequery', label 'legent text'}.
|
|
|
+ this is usually populated by a stringquery panel wher the query and label
|
|
|
+ parameter are the same
|
|
|
+ * interval :: Generated automatically. Tells ES how to bucket the data points
|
|
|
+ * 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
|
|
|
+ ### Group Events
|
|
|
+ #### Receives
|
|
|
+ * time :: An object containing the time range to use and the index(es) to query
|
|
|
+ * query :: An Array of queries, even if its only one
|
|
|
+ #### Sends
|
|
|
+ * get_time :: On panel initialization get time range to query
