In Relatics, most information is managed in tables and trees. For end users, this makes entering information and creating excerpts of the data very intuitive. Over time, the need for a visual way to have a simple and quick insight into the project information often arises. By making a few small additions to the theme, a progress bar can be created with conditional formatting. Examples include a bar that indicates verification progress, or a bar which shows the current risk score compared to the maximum possible! In this article, I will explain step by step how to set this up.
Step 1 - Retrieve data
To display the progress of a certain element in Relatics, we need two values: the current value, and the 'end point'. In the example, I am using properly completed Verifications of an Object. To retrieve the values, I will consistently use this Query as an example in this step-by-step instruction.
In Relatics, you can count the instances that are retrieved by a Query using an 'Aggregate function', as described here in the Knowledge Base. Using the Query in this example, I retrieve the number of planned verifications and the number of completed verifications via two Derived Fields (on the root node).
Derived Field: completed
Derived Field: planned
Step 2 - Compiling the HTML progress element
Because Relatics is a web-based tool, we can use HTML and CSS to modify our visualisation. One of the elements which can be used in HTML5 is the progress element. With this element we can quite easily create a progress bar, for which we only need the value and the maximum.
Below, the following Derived Field with references to the earlier Derived Fields in bold.
Derived Field: progressbar
<progress value=[completed] max=[planned]></progress>
Step 3 - Show the progress bar
A progress element cannot be displayed directly in a cell using HTML, which is why I enclose it within a div element. As it is fairly easy to expand the view, I also place the calculated value in front of the bar, and the 'end point' behind it.
Check the selection-box for the output of this Derived Field, and have a quick look at the first result.
Derived Field: Verification progress
concatenate("<div>",[completed]," ",[progressbar]," ",[planned],"</div>")
Step 4 - Prepare the formatting with threshold values
We will use CSS to format the progress bar. To do this, we have to include a calculation in our Query that converts the threshold values of the progress into a colour. In this example, I use the following threshold values (but you could also set absolute values, for example):
- More than 90% completed: Green
- More than 75% completed: Orange
- Less than 75% completed: Red
Derived Field: class
Step 5 - Adding the styling with the class attribute
For the design, we still have to link the class we need (containing the reference to the colour) to the progress bar we created earlier.
Note: because the CSS has not yet been modified, you will not see any difference until Step 6 is completed.
Derived Field: progress bar
<progress class=[class] value=[completed] max=[planned]></progress>
Step 6 - Modify Relatics.css to format the progress bar
The final step is to adjust Relatics.css in the File explorer. To do this, we need to know which theme we have to change (in practice, I have noticed that there are sometimes multiple themes in the File explorer). You can find the theme via Workspace Studio | User Interface | Portals | ‘Your portal’ | table Theme and logo | Theme.
Once you know the theme you need, you can look up the Relatics.css in Workspace Studio | User Interface | File explorer.
Add the code below to the Relatics.css of your theme. Before making any adjustments, it is wise to make a backup, or have one at hand.
Extension to Relatics.css
