can you pull in existing Kibana visualizations into your new app? For example if I want to create a line chart visualization above a discover visualization and populate it with certain information based on an ES query I have run

I am a newbie creating an OpenSearch Dashboard. I wonder whether it is possible to customise the axis of the charts that are created. For example, if I was representing information based on countries, would be possible to add images or pictograms about flags?
Many thanks in advance.
So I am not sure that you can put images there (without writing a custom plugin that is). What you could do is enrich the name fields with their respective countries flags. This transform could be done with a scripted field from OpenSearch Dashboards or if you are using fluentbit you could use a calculated field with a dict mapping.
I used this example in order to create a simple Kibana dashboard with a streaming data. So, the example runs a Flink program to simulate a streaming data flow and to save it into Elasticsearch in real time (version 1.7.3). The dashboard is created in Kibana 4.1.3.
The problem is that the map is not visible in Kibana dashboard. See this screenshot.
I followed Readme step by step, but for some reason the example SlidingArravalCount.scala is not working properly. Also, since this is a streaming data (simulated), I expected to see a dynamically updated map in which the colors of rectangles are changing in real-time, but I see a static image all the time. To see updates, I should click on Refresh button. Is it possible to setup an automatic refresh in Kibana 4.1.3?
Also, my visualization Map is not shown in a Dashboard.
Let's say I have a visualization that is displaying production line output over time. There are 6 production lines and I only want to display one production line on the visualization at a time. I can add a Production Line filter to accommodate this.
I want to create a dashboard view for each production line. So I want to create 6 dashboard views each with the same visualization filtered for a different value. However, I do not know how to do this without creating a copy of the visualization and dictating the exact Production Line filter.
Reasons for doing this:
I want to publish the specific dashboards and be able to embed the view into a SharePoint site (that is Production Line specific) and not require the user to filter the view each time
If I make a change to visualization, I want it to be transferred to all dashboard views for all Production Lines and do not want to make the same change to 6 visualizations.
Is this possible?
You can't do it with a dashboard. Try doing it with stories though. Create one story point for each production line. You can drop a single copy of your viz onto multiple story points, each with filters independent of each other, and any changes to the worksheet will be reflected in all six story points.
Yes it is possible. You could use a story as Sam M says, with 6 views of your dashboard each with a different filter setting,
Another choice that works in the embedded viz use case is to create a single dashboard, and apply a filter to all the worksheets on that dashboard. When using Tableau Server, you can supply the filter value as a query parameter in the URL (see the documentation)
After you test it out and are happy with the result, you can remove the filter control from the dashboard so it is no longer visible. You can still control the filter setting via the URL (or via the JavaScript API)
This allows you to adjust the viz that users see in your embedded view without making them manually select the filter setting, and also without creating six nearly identical dashboards.
I'm looking for a report engine which may:
connect to data source via JDBC
create logic data set by grouping/aggregating the raw data
include a data filter on the top of each report, which allows my client use the report interactively
add custom charts, in my case, it's ECharts https://github.com/ecomfe/echarts
support multi-tenancy paradigm (new requirement)
Now BIRT and Pentaho are the two players on my table.
For pentaho, it's really hard to find useful document to at least clarify if it's capable. Please if you're familiar with it, let me know if pentaho community version meets my requirements.
For BIRT, I've found evidence it support my first 3 needs. But for custom charts, I can only find examples/docs about adding custom IMAGE/SVG charts. As ECharts is based on canvas, I'm not sure if it's possible to integrate ECharts with BIRT.
Thank you!
Yes, it is possible to integrate javascript charts in BIRT. Basically:
Select the top-level element of your report outline -> Script tab -> clientScripts
Include here your echart resources (.js and .css) using "head.js" (see link below for more informations)
Add a text element to the report
Set the type of this new element to 'HTML'
In a script tag, initialize your echart object in a "head.ready()" instruction (see link below for more informations). The tricky part is to understand how to use a server-side dataset in a client-side chart within this html script.
You can find more informations and a full example of a such report here, this example embeds a jvectormap in a birt report. Furthermore, see a live demo here, where a JIT chart is integrated in a BIRT report.
However since these charts are created using a client-side framework, obviously BIRT won't be able to export them in PDF format. You can see in the live demo linked above, how a BIRT report can easily handle a different output when users export to PDF.
You can do it in Pentaho, but which tool to use it's a matter of debate.
Using Pentaho Report Designer:
- Connects to DBs using JDBC;
- Allows grouping rows based on a field or fields and calculating functions such as running sums;
- Can use selectors (single or multi-valued selectors) to interact with the report, passing the selector values to the queries;
- As far as I can tell, you don't have many options to choose a specific charting engine.
However, you can use CCC as the charting engine, which is a Protovis based Javascript charting engine, cross-browser compatible (for the most part), renders SVG charts with a decent fallback for IE (I believe the fallback is flash but I'm not sure if it changed recently) and produces decent looking charts.
If you HAVE to use that chart library, then I suggest using C-Tools dashboards instead, where you can embed as many different JS files you want and you have full control over the JS and CSS of the page. But most of the reporting functions from PRD will have to be implmented by you.
I am working on some Oracle APEX Plugin development and wonder whether the following requirement is possible.
I basically would like to be able, via a plugin, create a form with say six page items, where two of those page items might be LOVs, another two are page items are text fields, where users have to enter values and the remaining two are display items only.
Based on this form requirement, I want to be able to upload/install this plugin within other Oracle Application Express apps/schemas, so when installed within other apps, this plugin is rendered within a region and the data is stored within a table in that schema, but using the form described above.
Can this be achieved building a plugin in Oracle APEX, and if so, how?
Create a stock application with the pages and regions that need to be replicated, export that, and import it into the other workspaces that need it. Then, when developing an application, copy the regions and/or pages as necessary from that stock application.
