Kibana pie chart for text data - kibana

I have text data in Elastic, field name is buildResult , type is text and value can be either Success or Failure:
I want to have Pie chart to illustrate Success vs Failure
Could you please advice on chart setup or share some example for text type?

Split the piechart using text filters to get the result you want.
The picture below is taken from the data configuration of the piechart visualization in Kibana.
This works for string fields - I guess it would work for text fields also.

From what i know the best way is to use keyword data type in these cases
elasticsearch keyword
when the field is keyword you can use simple terms aggregation to split the pie between the deferent keywords

Creating featureCollection histogram with title

I am trying to create histograms from a feature collection based on a property in google earth engine such that I can provide a title and axis titles. the ui.Chart.feature.histogram does not seem to allow for this. It does, however, provide the data for the chart correctly.
I have also tried using the aggregeate_histogram(property) method, converting that to a dictionary, and accessing the .values() and .keys() from the dictionary, and sorting them. This, however, puts the data in order but not logically, e.g., 3 appears right after 29, not before 4. Make sense?
What I'm getting using ui.Chart.array.values() and the dictionary values and keys, vs. the ui.Chart.feature.histogram:
result of ui.Chart.array.values()
vs.
result of ui.Chart.feature.histogram()
I didn't realize the .setOptions() method could also be used on the ui.Chart.feature.histogram!! This allows me to provide a title.

How to list unique values of a particular field in Kibana

I am having a field named rpc in my elasticsearch database and I am displaying it using Kibana. When I search in search bar of kibana like:
rpc:*
It display all the values of rpc field but I want to have only those value to be displayed which are unique.
I have been playing around with Kibana4 since a couple of weeks now. I find it intuitive and simple and the experience has been great till now. Following your question, I tried getting unique results via a Data Table visualization. Why? Because I personally find it easier to understand. Following are the steps:
1. Get unique count
Create the visualization (Visualize -> Data Table). First lets get
the count of how many unique entries we have for a particular field
(We will use this in the later part for verification). I'm using
clientip.raw but as I see, it will work just fine with any friendly
field name too.
2. Set the aggregation right
Set you aggregation back to count and have a Split Rows as follows. Not doing this will give you count 1 for each field value (since it is looking for unique counts) when you populate the table. Noteworthy part is setting the Top field to 0. Because Kibana won't let you enter anything else than a digit (Obviously!). This was the tricky part. Hit Apply and you'll get the results. Unique field values and the count of each of them.
3. Verification:
Going to the last page of the table, we see there are exactly 543 results. This is how I know it works.
What Next?
You save this visualization and add it to a Dashboard. There you can always check the request, query, response and other stats.
Just an addition to the above mathakoot answer.
For the user of newer version (which do not allow bucket size of 0 anymore) just set a value greater than the maximum number of result
And report the value in the Options>Per Page field
I am using Kibana 6 so the UI looks a bit different than the older answers here.
Here is what worked for me
Create a visualization from your query, I used a line graph type (don't think it matters)
Under Data, set metrics aggregation = "Unique Count" and set field to your field.
Set x-axis aggregation = "Terms" and set field to your field.
Set Size > your number of records
Under Metrics and Axes, disable drawing of the graph, circles, and labels (this really helps the UI not lag)
Run query and then click "Inspect" and download CSV
Data
Metrics & Axes
I wanted to achieve something similar but I'm stuck with Kibana 3.1.
I simply added a panel of type "TERMS" and configured its Field = User-agent and left everything else on default values. This gave me a nice bar chart with one bar for each User-agent.

Displaying n-greatest in Kibana

In my elasticsearch backend, I have a index stats with a numerical field and a #name field.
I would like to display a pie chart (or some other panel type) in Kibana where you can list the top N #name where the percentage in the pie represents the percent of the total fields are represented.
For example, in one index, you might have
#Name: John
Field: 5
#Name: Robert
Field: 5
Then I would have a pie chart with John and Robert both at 50%. Is this possible on Kibana?
Yes what you are trying is very much possible in Kibana 4 with simplicity & ease.
If i am able to understand correctly you want to show TOP N results of a specific field in pie chart.
To do so follow the following steps:
Clicking on pie chart under visualize tab (Create a new visualization).
Selecting a search source - From a new search
Go to Split Slices, select aggregation as terms.
Then enter the field and select TOP in order & size (denote no of records you want) ex:5 will show TOP 5 records.
Click on Apply & the pie chart would be generated :)
PS: Feel free to contact me for any further issue, would be happy to guide :)
Yes; It is possible in Kibana; If we are using Kibana latest version then it would be easy for you to create visualization; Look for Pie-chart in visualization and then proceed next; Fill the appropriate fields and I hope it is not that tough to understand while filling the fields; It will render the pie chat on clicking the "Green" > button.

Kibana i see Indices and fields but cannot Chart or Visualize

I curled the sample bank data to elasticsearch. On Kibana I see under the Indices bank and on visualize all the fields (age, balance, etc.) on the left but cannot see charts on the right. It always says No Results Found. On the left I selected Y-Axis - Agg as Average and Field as Balance and X-Axis Agg as Terms and Field as Age, all from drop downs. Then I used the APPLY action. No error is displayed, but neither is a chart.
What am I doing wrong here? Using curl I can check the elastic search and see that the data exists. No matter what I do, I do not see any logging in the elasticsearch logs under /usr/share/elasticsearch/logs.
I don't know if you figured this out or not but I had the exact same problem. I was using a mapping type that did not contain the field I was trying to visualize. Make sure the _type field contains a mapping with the correct indexed fields.
When setting up my initial index patterns, I glossed over specifying the 'Default timestamp' field, and the UI didn't insist on having one. The fix was to delete my index patterns and re-create them them, with the specified timestamp field. Everything snapped into place.

SSRS Chart Blank with DateTimes

I am working with SSRS and having trouble creating a graphical chart to display data. My dataset is very simple, as it only has one column which is a datetime field (known as CreatedOn).
My SQL query is:
SELECT [CreatedOn]
FROM [Incident]
WHERE CreatedOn > DATEADD(m,-11, DATEADD(
month, DATEDIFF(month, 0,CURRENT_TIMESTAMP), 0))
My goal is to have the query results show up in a chart and have them grouped by year and by month, as well as sorted. For example, I should be able to see that 40 incidents were created in February 2005. Those 40 incidents would be represented graphically as a single bar (it is a bar graph) with the number 40 on top (or somewhere).
My issue is that either my chart shows up completely blank, or the report fails to run. When it fails to run, the error I receive is:
the value expression for field 'CreatedOn' contains an error: conversion from string 'CreatedOn' to type 'Date' is not valid.
I have tried using SSRS expressions on the CreatedOn field, such as CDate() and FormateDateTime(). That does get the report to run, but the chart shows up blank. I would not think that the field should have to be formatted or converted in SSRS since it is already a datetime field at the database level. I have tried about 10 different combinations of groupings and sorts, but my chart always shows up blank. I have even used CDate() and so forth in the grouping and sort expressions which are a part of the chart.
How can I get my bar chart to work (a.k.a. show datetimes, grouped and sorted)?
I am going to go off the assumption:
You have more data being pulled than just the ‘CreatedOn’ field.
a. Because if you don't it will be difficult to create a chart as you have nothing else to compare it too.
If this is an accurate assumption here is an example of how to create a chart and have the data formatted by dates.
When designing a chart you need to take a lot into consideration. First I like to ensure that I have as little null data as possible. This causes charts to act wonky (at least from my experience).
Second is how the data will be represented.
We have several things to consider when we think about charts and groups.
There are Category groups, Series groups, and then the Values.
According to Microsoft: charts have a direct similarity to Matrix’s. They act the same way:
The Column groups of a Matrix are similar to that of the Category Groups in a chart.
The Row groups of a Matrix are similar to that of the Series Groups in a chart.
The Data area of a Matrix is similar to that of the Values Groups in a chart.
Setting Up the chart:
If we want the number of Incidents sorted by Year and then Month it might look something like this:
Year by Category (You can use your group by Expression here) =Year(Fields!CreatedOn.Value)
Incidents will be in the Values section =Count(Fields!Incidents.Value)
Once you have that working and showing data I would then start adding in the data for the month. Again thinking about how you want to have the data displayed. You could then add a second Grouping on the category under the other one with your month function.
Another Useful link on charts (I know this is a little older but it’s details are still relevant)
*Side Note: When dealing with dates it can be a little tricky especially if SSRS is not recognizing something as a date. Here is a useful link that I have used when dealing with dates.
Dates
I hope this helped!
The issue was that the CreatedOn date field was not being defined correctly.
My data source was defined using an expression which depended upon parameters, using the expression: ="Data Source=sql01;" & "Initial Catalog=" & Parameters!ParentID.Value. Because the dataset must be defined at the runtime of the report, I was not able to refresh fields in the dataset using the "Refresh Fields" button.
I thought that I could work around this by defining the CreatedOn field manually. On the first attempt, SSRS threw an error at runtime claiming that I was trying to convert a string to a date, which basically meant that it perceived the CreatedOn field as defined within the dataset as a string. So I then tried to use the CDate() expression in the definition of the field, but that left me with a completely blank graph.
The solution was to:
Delete all of the fields I already had defined within the dataset
Temporarily hard-code my data source to use a database (Data Source=sql01;Initial Catalog=MyDatabaseName)
Click the "Refresh Fields" button within the dataset
Go back at set the data source to the original data source I wanted which depended upon parameters.
