Deneb Exercise - Progress Tracker
Many gauge visuals take-up a significant amount of screen real estate, and I wondered if Deneb/Vega-Lite could be used to minimize the required space. Here’s what I came up with: This example uses a number of optional Deneb/Vega-Lite components, including: a title block c/w subtitle a transform block to extend the dataset a layer block with 4 specifications as follows: a bar mark for 100% width background (target) a bar mark for progress width = actual/target; percent) (actual) color = gr...

How to change the colors of your visuals based on the selected measure
Have you ever wondered how people do the trick below? Say no more! I'm going to share with you all the tricks that you need to do to achieve something like this. In my example, I created a report where you could switch the measure the charts were showing, and with that, the color of the charts and KPI cards changed to. The first thing you need to do is create your base measures. In my example my base measures were: Number of Orders = count(Amazon[Order ID]) Orders Value £ = SUM(Amazon[Amount]) I

Creative ways to show filter selections on your Power BI reports
When I'm developing reports, I'm asked multiple times to "hide" the slicers/filters from the report page. Usually this is to make space in the page for other visuals and because customers don't want to use the filter pane for some reason. This happened so many times, and only in the last couple of months I decided to try some things out and get a bit creative with Power BI. I came up with two solutions, which I think work great in these scenarios. Remarks: - This might not working very well if y

Clarity and Aesthetics in Data Visualization: Guidelines
Last week I introduced mini-projects as one pillar of my graduate visualization course. A interesting outgrow of that activity is a set if data visualization clarity and aesthetics guidelines we developed over time while reviewing the solutions our students submitted for these exercises.
Clarity and Aesthetics in Visualization: Attention, Contrast, Grouping
Three concepts from visual perception that can help you think better about clarity and aesthetics
What Matters, Really, is Effective Data Thinking
Reflections on my frustration teaching data visualization without focusing on effective data-driven thinking
The project requires students to formulate a data analysis and presentation goal and to generate (1) a series of “data questions”; (2) corresponding data transformations and models; and (3) a set of initial sketches of the associated visual representations.
mottos in the course is that data visualization is not only about visual representation, but also about asking good questions and generating appropriate information from the data
I do not have a definite answer to these questions, but I can’t help but notice that we, as a community, may be at fault here. With our obsession with whether a pie chart is “better“ than a bar chart, is it possible that we have lost sight of what actually really matters? Let me be blunt: it does not really matter how pretty a visualization is and whether it uses the latest technology or the fanciest graph. These are nice things to have, for sure. But at the end of the day, what really matters is thinking. Appropriate and effective thinking.
What Makes a Data Visualization Confusing?
Why are some visualizations so easy to understand at first sight while others seem to be some sort of graphical puzzle? Why do some visualizations need to be relearned every time you see them again, whereas others need only one simple initial exposure?
I believe there are two distinct phenomena in this space that often get conflated: novelty and something I’ll tentatively call cognitive incongruence.
While, for sure many representations are confusing only at first sight and have a learning curve, it is also clear to me that some representations are confusing no matter how many times you use them
If we set aside the clear case of visual representations that are confusing only at first because they are novel, it would be interesting to understand better what makes some graphs confusing even after multiple exposures. It seems to me there could be interesting insights to gain from such an exploration.
An example of the second case is the burning embers I mentioned above. To me, they look a lot like bar charts, so when I see them, I try to read them as bar charts, which is the wrong mental model for them. A similar problem exists with connected scatter plots. I want to read them as line charts, but this is the wrong way to read them, so I get confused.
One hypothesis I have is that they evoke the wrong analogies, either because there is a mismatch between the visual representation and the information they represent or because there is a clash with mental models of similar representations we have acquired in the past.
