Note: This visual will be available in the AppSource only in the first week of September 2019. To get the latest build, reach out to us here.
Tag Cloud gives you a more visually interesting way to look at the tags or words that come along with your data. It can be product descriptions, tags from twitter, names of customers or even employees. Most of the customers like tag clouds for the way they expose the extra-miler tags within the dataset based on a specific criterion like the Sales value or Market Share.
For this blog, I am using a dataset with a list of movie titles along with their Domestic Gross and Critic Score. Let’s jump into the features that come along with xViz’s Tag Cloud custom visual right away.
Key Features – Summary
1. Use whole phrases or individual words
2. Control number of tags shown
3. Control orientation of words
4. Exclude specific words
5. Remove special characters (read the tooltip for this property; use an example)
6. Tooltip that captures frequency or performance
7. Color range options
8. Categories with Negative Values
1. Use whole phrases or individual words: At times, breaking down phrases or continuous texts within the data to show on your tag cloud doesn’t actually make much sense. For example, take a look at the screenshot below.
By looking at the tag cloud, some of you might understand that it has something to do with Avengers or maybe at least it is about movies. However, breaking down movie titles into words to form a tag cloud doesn’t give me much information.
Now, let me turn off the “Split phrases into words” and look at the same data.
As I have included the Domestic Gross as the Size Value, I can easily make it out from the tag cloud that Black Panther is at the top of the list followed by Avenger’s Infinity War.
2. Control number of tags shown: Your dataset could be large enough to swamp up the Avengers. However, the Tag Cloud gives you the flexibility to control the number of tags that you want to see on the Tag Cloud.
You have the option to restrict the Maximum number of Tags that get displayed. This would help you to focus on the major tags out without disturbing the readability of the visual.
3. Control the orientation of words: Generally, any Tag Cloud arranges all the tags or phrases in random directions with all the visual space that is available. But, in this visual we have the ability to control the orientations of the tags to make the visual more appealing. There are a couple of properties that you can play around with to understand how you can control the orientation of the tags in your visual.
4. Exclude specific words: There might be common words like “THE” or “A” in your dataset that keep popping up right on top as they might be present in a number of places within the dataset. In such cases, you can use the Exclude words feature which let’s you restrict the words that you’d want to filter out of the Tag Cloud. To exclude multiple words, you can comma separate the words as shown in the screenshot below.
5. Remove special characters: One another pain that most of the users might phase in this is the presence of a lot of special characters. It can be anything right from a period to comma or even the $ sign. The Tag Cloud comes along with the powerful “Remove Special Characters” option which serves as the Gauntlet of Thanos and removes all the Special Characters in the snap of a finger. Here’s the access to your Gauntlet.
6. Tooltip that captures frequency or performance: By default, the tooltips displayed for the tags display the Size Value that is added to the visual. Here, we have added the Domestic Gross as the Size Value and hence hovering over the tags would show you that.
However, you can add an additional tooltip field which gives you a little more information about the tag. Let me go ahead and add the critic score on to the Tooltips field to view the additional detail on the tooltip itself.
7. Color Range Options: Tag Cloud comes along with an option to choose the color theme that you want to work with. By Default, it is set to the Power BI theme that you’re using. You can also switch to a Single Color theme or Color Range theme.
The Color Range Theme uses the value of the Size measure itself to give different shades to the tags by default. However, you can add another measure into the “Color Value” field if you would want the tags to be colored based on that value.
This gives you the ability to infer two measure, one by size and another by the color just at once.
8. Categories with Negative Values: Certainly, any tag cloud limits the data members until their value is zero and filters out the other with negative values.
For example, a few stores that you run are performing low and are in a loss but, you’d still like view their magnitude in comparison with the higher performers. In that case, restricting the negatives might be a downside and xViz’s Tag Cloud for Power BI gives you the flexibility to use categories with Negative values too. Thumbs Up!
