Dashboard creation with Pentaho and CDE. Step by step screencast tutorial.

Introduction

This screencast tutorial shows how to create a dashboard using Pentaho and the Community Tools (CTools), especially the Community Dashboard Editor (CDE). A dashboard with two different bar charts is created step by step, including the layout, data sources and components configuration.

It’s very similar to this tutorial: Creating Dashboards with CDE, but it also includes other aspects like the details of the MDX Queries creation or the use of a CCC Bar chart to create a Percentage Stacked Bar Chart with a Line. This type of chart is possible since the latest CDE versions.

To install Pentaho + CTools you can follow this step by step guide from the creators:

http://pedroalves-bi.blogspot.com/2011/12/back-to-basics-step-by-step-pentaho.html

The tutorial is divided in four parts and the source files are available.

Part 1. A Bar Chart with several measures

A new CDE dashboard is created and a CCC Bar Chart is included. The data source of the chart is a MDX query over the SteelWheelsSales cube, which comes with the default Pentaho BI Server.

Part 2. A Stacked Bar Line Chart by percentage

The second part introduces how to create a Stacked Bar Line Chart by percentage. The design of the MDX query is showed including the use of calculated members. The SteelWheelsSales cube is used again.

Part 3. Parameterizing the MDX queries

In this part a parameter is added to let the user select different measures to be displayed in the charts.

Part4. Charts tuning

To finish, some properties of the charts are used to change their appearance like colors, text fonts, string formats, etc.

    Cordial Greeting.
    First of all thank you very much for the contribution.
    I am working with pentaho with version 3.9 and CDE (CDE-bundle-1.0-RC3).
    I wonder which version you have both platforms at the time of the tutorial, as for example in part 2 of video tuto, modify a property of “CCC Bar Char” called “Bar Line” and I have none in addition to completing and implementing the “source” did not deploy anything in the “preview” and asked whether this property is due or that it should be.
    Thank you very much.

    Cordial Saludo.
    Primero que nada muchas gracias por el aporte.
    Estoy trabajando con pentaho 3.9 y con la versión CDE (CDE-bundle-1.0-RC3).
    Me gustaría saber que versión tiene ustedes de ambas plataformas al momento de realizar el tutorial, ya que por ejemplo en la parte 2 del video tuto, modifican una propiedad del “CCC Bar Char” que se llama “Bar Line” y yo no la tengo, además al terminar y aplicar el “source” no me despliega nada en el “preview” y quisiera saber si es debido a esta propiedad o a que se debería.
    Muchas Gracias.

      Hi John,
      There are several CDE releases after the CDE-bundle-1,0-RC3
      For the tutorial I used the Pentaho BI Server 3.7, but you only have to upgrade the CDE version. The barchart component of the newer versions has the “barline property”. You can read this post from the authors that explains how to do the upgrade:

      http://pedroalves-bi.blogspot.com.es/2011/12/back-to-basics-step-by-step-pentaho.html

      Basically you only have to run the ctools-installer.sh
      If you are a Windows user you could open the ctools-installer.sh file with a text editor, see what the script does and then do the same tasks by yourself.

      Kind Regards

      PD: Con un poco de paciencia lo lograrás, si tienes más preguntas no dudes en escribir.

      Dear Paulo,

      Right now I’m working in another project with a different technology. I don’t have an enviroment set to test a solution. I think in the Pentaho Forum you will find a possible solution for your needs: http://forums.pentaho.com/forumdisplay.php?80-Community-Tools-CTools. When I have enough time I would like to post a similar tutorial but using the graphic components of the Pentaho Report Designer instead of the CCC. It is possible to embedded in your Dashboards.

      Kind Regards

      • Paulo Silva says:

        Hellho,
        Thanks for your quick response.
        I already am part of the pentaho forum and I’m there looking if there is similar problems like my.

        Based on my experience, it is easy to create graphs in pentaho report design. I do not know is how to integrate them in the dashboard. Your future tutorial will be very helpful.
        Keep up the good work.

        King Regards,

        Paulo

    This is awesome work. Thank you very much.

    I downloaded the samples (thanks again). I added expanded the rar and copied the folder (demo-1) to my solutions folder. I can see the sample solution folder on the browser list. When I click on the folder I see the cda files but not the actual dashboard file. The samples in Steels Wheels > Dashboards are fine.

    Is there some step I am missing. I use the all powerful joe/password login. BI Server 3.8.

    • pauldj54 says:

      Hi Rob, you’re welcome!

      Which version of the C-Tools are you using?
      I think there are several changes in the C-Tolls since I created the demo. I recommend you to create a simple dashboard with your installed version and use my screencast as a guide. Then if it works you can increase the complexity of the dashboards. If not you’ll have to troubleshooting the C-Tools installation.
      By the way, can you open the cde dashboard sample?

      Let me know if you have any trouble.

      Kind Regards,

      Paul

    Hola Paul!
    he diseñado un dashboard en un bi-server y ahora debo migrarlo a otro. ¿Me puedes orientar en cuanto a los pasos a seguir?
    Para empezar, ¿cómo hago para que al copiar el archivo en pentaho-solutions éste quede visible en el panel de navegación del servidor?
    Muchas gracias desde ya!

    • pauldj54 says:

      Hi pdarscht,

      When you want to move a dashboard from one server to another please don’t forget to copy the 3 files with the following extensions: .cda, .cdfde and .wcdf
      Example: if your dashboard name is sample_dashboard1, you need to move to the desire folder in the new server the files: sample_dashboard1.cda, sample_dashboard1.cdfde and sample_dashboard1.wcdf
      Then, you may need to clear some caches in the BI server to see your dashboard in the Navigation Windows.

      Hope that helps. Kind Regards.

    I am using Pentaho business analytics 4.5 with latest version of ctools installed.

    I created few dashboards and saved them in a folder. Now I want to edit those dashboards, i need to add some more components, change layout or change sql query used. But how the dashboard is edited?
    When i saved the dashboards, i can see .cda and _tmp.cda files of my dashboards. Further when i select them and click on edit it opens into CDA and shows XML code. I want it to open in CDE console,so that i can make the changes I want. Please guide how to do this.
    Is there anything specific to be done while saving the dashboard like saving into .cde format??Please guide

    • pauldj54 says:

      I´m sorry Anu, but I´ve never worked with Pentaho Business Analytics before. I’ve only used the community versions of the Pentaho BI Server. In any case, you should see not only the CDA icons in the windows browser but also the CDE icons. How did you install the CDE. Are you able to see the CDE Sample folder?

      Kind Regards

  7. Constanza says:

    Hola
    Estos pasos me ayudaron bastante para empezar a hacer dashboard, pero mi actual problema es tratar de usar “Dial chart component”, he revisado varios lugares y no me ha resultado.
    Si tú supieras de algún ejemplo para CDE que exista para basarme en ese o los pasos de cómo se configura el componente lo agradeceré, ya que es para un trabajo de fin de año en mi universidad.

    Muchas gracias por cualquier ayuda.

    How would I use this Dashboard in an external web app. like a portlet for example?

  9. rahul tiwari says:

    hello Paul,
    your post is amazing. But I am stucked in a serious issue. I have developed a CDE dashboard using JDBC query in my local BI server 4.8 now I want to publish this Dashboard to Production server of pentaho. But when I am copying these files to production BI server then I am unable to get an output. Please help to migrate Dashboard from one BI server to another.

    • Hi Rahul,

      I remember I faced some similar problems the first time that I deploy dashboards in the production enviroment. Are you moving the complete folder where the dashboard is stored or only the specific file(s)? Can you please take a look in the Tomcat log and search any error message when you try to open the dashboard?

      Kind Regards,
