            Fixing Cluttered Titles on Graphs
            Asked 2022-Mar-07 at 19:08

            While my solution isn't exactly what you describe under Option 2, it is close. We use combineWidgets() to create a grid with a single column and a row height where one graph covers most of the screen height. We squeeze in a link between each widget instance that scrolls the browser window down to show the following graph when clicked.

            Let me know if this is working for you. It should be possible to automatically adjust the row size according to the browser window size. Currently, this depends on the browser window height being around 1000px.

            I modified your code for the graph creation slightly and wrapped it in a function. This allows us to create 25 different-looking graphs easily. This way testing the resulting HTML file is more fun! What follows the function definition is the code to create a list of HTML objects that we then feed into combineWidgets().

            Not sure to fully understand what you are looking for but:

            1. If you want the vertices to be placed randomly and not on a circle, you just need to use the argument layout = "layout_randomly" inside the visIgraph() function.

            2. If you want the vertices to be placed randomly and on a circle, you need to use the permute() function and then just add the argument layout = "layout_circle" inside the visIgraph() function.

            Altair: How to color when there are more categories than colors available

            Here is the code taken from the Altair documentation on color schemes.

            ANSWER

            Answered 2022-Feb-08 at 01:33

            It is not possible to extend a color scheme automatically via Altair/VegaLite. You would need to manually define the colors you would want to use, or switch to another color scheme, as you mentioned.

            Note that when you are using this many categorical colors, it can become quite difficult for the reader to parse the information in the plot and it is usually better to break down the plot into multiple plots via faceting, or use labels/hovering to encode some of the information instead of relying solely on color. There are some good pointers on this topic in this book chapter.

            Shinyapps.io Converting All Numeric Data to NA
            Asked 2021-Dec-27 at 23:49

            I am trying to render a table on shinyapps.io, but it is populating with all NA's. I am scraping NCAA basketball spreads from https://www.vegasinsider.com/college-basketball/odds/las-vegas/. Locally, the table renders fine. But on shinyapps.io, all the numeric spreads display as NA's. It only displays correctly on shinyapps.io if all the spread values are characters. But then I cannot perform any math operations. As soon as the BetMGM, Caesers, FanDuel columns are numeric, they display with NA. I'll provide some code and data to help recreate the issue. There was a lot of data cleaning steps that I will skip for the sake of brevity.

            @akrun here is the code to scrape the table. I do this and then some regex to split apart the game_info into components.

            ANSWER

            Answered 2021-Dec-24 at 16:58

            It seems that the spread_table after scraping may be post-processed in a way that couldn't convert the extracted substring into numeric class - i.e. when we do as.numeric, if there is any character, it may convert to NA.

            In the below code, select the columns of interest after scraping, then extract the substring from the 'game_info' column to split into 'date', 'time', 'away_team_name' and 'home_team_name' based on a regex pattern matching and capturing ((...)) those groups that meet the criteria. (^(\\S+)) - captures the first group as one or more non white spaces characters from the start (^) of the string, followed by one or more white space (\\s+), then capture characters that are not newline character (([^\n]+)) followed by any character that is not letter ([^A-Za-z]+), capture third groups as one or more characters not the newline followed by again the characters not a letter and capture the rest of the characters ((.*)). Then loop across the 'BetMGM' to 'FanDuel', extract the substring characters not having u or - and is followed by a space ((?=\\s)), replace the substring fraction with + 0.5 (as there was only a single fraction), loop over the string and evalutate the string

            Vega: empty bar mark
            Asked 2021-Dec-20 at 20:29

            Does Vega/Vega-Lite/Altair have a builtin method to draw a special mark for empty bars? When x == x2 no mark is currently shown. Perhaps a vertical rule mark of the same expected bar color as derived from a third encoding? Or perhaps a semi-transparent bar mark covering an expanded region with a red border?

            You can set the stroke color for the outlines of the bars using something like mark_bar(stroke='gray') (it defaults to transparent): then empty bars will be shown by their outline:

            Splitting the color legend in a repeat spec in vega

            I am using a dataset with the following columns: date, counts, country, engine, and type.

            I have created a view with three charts using the repeat operator. The charts show dates on the X axis, counts on Y, and then the bars are split by either country, engine, or type.

            I am happy with how things look but I would like to have three separate color legends, one for each domain (so a legend for countries, a legend for type, and a legend for engine). How do I do that?

            There are two issues here:

            1. Your top level encoding maps x to field ts, but "data": { "values": [] }, does not have any field named ts, so the encoding is undefined and no mark is drawn.

            2. The datum encoding is applied to each entry in the associated dataset, but your dataset has length 0, and so there are no entries. You can use "data": { "values": [{}] } instead.
