CSC/ECE 517 Fall 2017/E1792 OSS Visualizations for instructors

Issue Statement:

Issue 1: For links in each cell. We are not sure what will happen if we click the link and which page will open.

Approach to solve issue 1: The issue is about the cell contains link to different pages in expertiza, but there is no way to know which cell is linked to which page. So user don't know the destination page when he/she clicks on some page. So we know that there is link in each cell, so we will show a hove over text displaying the link of the destination page.\

Issue 2: The scale is blue to green, which does not make sense. And colors will change randomly each time loading the page. It will be better to scale from red to green.

Approach to solve issue 2: Here the color coding is blue to green and also it changes randomly. So we will use RBG color coding to make it red to green. We will use percentage to decide color coding. For example if it between 0 - 20% then make it red and so on. This way no matter what scale is being used it will always have appropriate color coding.

Issue 3: Two adjacent bar represents the response in round 1 to round k. It makes sense only if the rubrics in all review rounds are all the same. If the instructor implements the vary-rubric-by-round mechanism, this visualization will not make sense.

Approach to solve issue 3: Here The problem is that the the review responses show in a grid format that shows all the reviews from round 1 to round n. But this is ok when the rubrics is same for all the rounds. But when the rubric is different from round to round this view doesn't make sense. So what we are thinking is creating different grid for each review round. That will solve the problem for when the rubric is different as well as when the rubric is same.

Issue 4: The table is presorted by teams, but you can now also sort alphabetically. The cell view looks way too long, and should be divided into partials.

Approach to solve issue 4: Here we can sort the select query with appropriate column alphabetically, or we can sort the table automatically according to user criteria using dynamic table format. And the long view issue can be solved by using paging.

Test Plan:

Issue 1: Check the link matches to the hover over text Issue 2: Check the color coding when different number is given in different scale. Issue 3: Enter multiple reviews with different rubric and check different table/grid shows for each review round separately. Issue 4: Check if the table is sorted with appropriate column alphabetically
