The KNIME Report Designer extensions provides a report template for each workflow and nodes to identify those data tables, that should be available within the report. The creation of reports consists of two clearly separated tasks:.
Thus, the KNIME workflow editor shows all the preprocessing that is performed on the data in a comprehensive way, while the report template editor reveals how the data will be presented in the report. The concept behind BIRT is fairly simple - in order to create a report, you need to define several elements.
These are primarily arranged in two areas:. The Master Pagewhich contains information for headers, knime advanced luck pdf download, footers, and titles common to every page in the report. The Layoutwhich details how tables, charts, images, text, and other items are arranged. When you open BIRT for the first time, you should see an environment similar to the figure below. Note that only a single report is associated with a given workflow. Report Itemswhich lists available features that we can drag and drop into the report, such as text, tables, images, and so on.
Report Editorwhich is where we place, edit, and manipulate features we want to include in our report. Property Editorwhich has a number of options for formatting and additional editing of our features. For example, you can change fonts, colors, page breaks, data references, and many other options here. The tabs available in this panel change dynamically, based on what we are currently working with in the Report Editor.
The easiest way to learn what the various panels do - and hence, what BIRT itself does - is to create a report! We will do this momentarily. But first, we need a dataset to work with.
For our basic report, we will use a dataset of restaurant inspection scores. It contains three years of data. It includes restaurant names, numeric IDs, addresses, and ZIP codes, along with associated inspection dates, scores, and descriptions.
The data is used to perform two tasks:. The workflow is presented below. In it, you can see that the data is first read in. For the first task, the data is sorted and filtered to produce a table containing our desired data, and the table is passed to BIRT using the Data to Report node.
For the second task, colors are added for inspection type, a scatter plot is produced, and the plot is passed to BIRT using the Image to Report node. By default, the Image to Report node sets the exported image size to x pixels.
This is usually too small for reporting purposes. In this example, we reconfigured the node to output images of size x You should download the workflow and execute it in full before continuing with the report creation steps below. This is done by clicking on the Report icon, shown here:. This brings up the interface shown above. First, click on the Master Page tab and set up our page orientation headers and footers in the Property Editor. You will notice that by default, the footer already contains a grid with some text and images about KNIME.
We will leave that be, but go ahead and click the Orientation drop-down and change it to Landscape, like so:. Next, let us add something to spice up the header. It would be nice to have a title for each page, and maybe an image as well.
If we want to have two separate items in the header, we should add a grid first, knime advanced luck pdf download. Grids help us to keep things organized in the editor. To do this, drag the Grid icon from the Report Items pane on the left side of the page into the header area at the top of the Report Editor. The header area is denoted by a dashed box colored in light blue. Set the grid size to 2 columns and 1 row, as shown, and click OK.
The grid will appear inside the header knime advanced luck pdf download. You can double click the Label to edit the text inside, knime advanced luck pdf download.
Also, when the label has knime advanced luck pdf download, you can edit the text properties in the Property Editor panel at the bottom of the screen. Enter the text "Austin Restaurants Report", change the font size to 24 points, and change the alignment to Center. Then, add an image to the header. In the leftmost grid cell, drag the Image icon from the Report Items panel. Select Embedded Image from the radio buttons shown, and add an image.
I used knime advanced luck pdf download map of Texas highlighting the location of Austin. If you need to resize your image, you can click-drag the corners to do so. Similarly, you can click drag the borders of the grid cells to move them as needed, knime advanced luck pdf download. At this point, you might want to check and see how your Master Page looks outside of the editor.
To see a preview, you can click on the View Report icon, which will generate the report in your web browser. The dropdown arrow next to the icon presents options for exporting to other common report formats. Once you are happy with the arrangement of the Master Page, you can move on to editing the layout of the report.
Click on the Layout tab to switch to editing your layout. First, knime advanced luck pdf download, drag in a Grid, and set the dimensions to two rows and two columns, knime advanced luck pdf download. Add a label in the top knime advanced luck pdf download cell, using the text "Bottom 30 Austin Restaurant Scores ". Center the label, change the background color to blue, and the text to bold white. Next, take a look at the items in the Data Set View panel. You should see icons for the Bottom 20 Locations table and Score plot generated from your workflow.
Drag the Bottom 20 Locations icon into the bottom left grid cell. When you do, you will be prompted to choose which fields in the dataset to include in the knime advanced luck pdf download. Always give the brown Report nodes in your workflow meaningful names! Note that the inserted table consists of a header row, a data cell row, and an empty footer row.
Center align the headers and data cells in the table by highlighting them, and clicking the associated button in the Properties panel at the bottom of the page, knime advanced luck pdf download. Next, place our score plot inside the grid.
Right click inside the bottom right grid cell, select Insert, then Knime advanced luck pdf download. A new dialogue will appear. Inside this dialog, select Dynamic image, and click the Select Image Data button. This brings up another dialog. To choose the data that should be bound to this image, select the ScorePlot dataset, and check the box, next to Image. Click OK. This produces a red X icon inside the cell, which can be disorienting.
At this point, the grid in the Layout editor should look something like this:. Having completed the layout of our basic report, there are a few more things we can do. For example, what if we wanted to accentuate values in our table, to make them stand out more?
This knime advanced luck pdf download called highlightingand is done via the Highlights tab in the Property Editor. Click on the [Score] cell of your data table, and then on the Highlights tab. This will highlight low restaurant inspection scores in a different color scheme in our report. What if we wanted to change the representation of values in the table to something knime advanced luck pdf download entirely?
For example, perhaps we wanted to collapse several numeric values into bins to make them easier to interpret for the reader of our report. This is called mappingand is done via the Map tab in the Property Editor. In the condition drop down, set the Zip Code knime advanced luck pdf download to and enter a display value of Downtown, as shown below. In the report, values of will now be changed to the text string "Downtown".
Now, take a look at your report in your web browser using the View Report button. You may also want to generate a PDF to see how that varies from the web preview. My report looks like this:. We also introduced the Austin Restaurants dataset, from which we can produce tables and charts of interest. On this page, we will present some advanced BIRT concepts, which you can use to generate more sophisticated visualizations of your data.
These include:. The workflow for this exercise is presented below. In it, we read in data and filter it by ZIP code, using global flow variables.
We also perform a quick aggregation using a GroupBy node to obtain the most recent inspection date for each facility, and join that information back with the score data. The processed data is used to perform three tasks:.
In the green box, we present grouping method 1. This method uses a Group Loop node to produce, for each ZIP code, a list of the top 10 scoring locations, along with a histogram of scores for all locations. It then passes two separate tables to BIRT - one containing the top restaurants, and the other containing the histograms.
In the blue box, we present grouping method 2.
