CONTEXT: Creating student performance data analysis, eventually to be summarised in a functional dashboard. One aspect of the visualisation is to select a student and a course and show their relative position within a box plot distribution.
PROBLEM: I cannot seem to effectively emphasise an individual circle in a jitter box plot. See below:
I have successfully :
- created the distribution of circles and box plot
- jittered the circles
- made the circles partially transparent
- conditionally coloured the circles according to their mark
- created a parameter to have a different colour for the selected student.
Seems like I have achieved it right? Well pedantic me is not happy with this. The problem arises when the reduced opacity blends the highlighted circle with the other circles. As can be seen in the image above, Jason, the selected student, has the highlighted colour but because the circle eclipses with another circle, the reduced opacity means the colours blend and ruining the intended highlight effect. Please note that the attached workbook is just a dummy set of data, my real data has much larger set of student scores and this means that the highlight is non existent, especially when the circle is in the middle of the distribution.
I have tried to do some research and made some attempts. Namely, I tried creating a duplicate "Mark" measure to create a dual axis and separate formatting; but of course when I filter for a student, it filters both duplicates of the "Mark" measure. I have not found anywhere in my research a way to have a different opacity for different parts of a filter. Additionally, I have tried playing around with different sized circles but that was equally unsatisfactory.
QUESTION: How can I make the individual selected circle have a format that will be very distinct while keeping the jitter, the conditional colours and opacity of the other circles ib the way I have formatted already?
