I wish to write 2D output strings in various colors. Normally I use printf, though I'm willing to hear other suggestions.

An optimal procedure would one where I pass it the string, and a ColorName color such as "DodgerBlue" or "xkcd blue", but I'm happy if it means passing my own hex code.  Thanks.

In reference to the nice application: https://www.mapleprimes.com/posts/209845-Dataframes--Looking-For-A-New-Flashlight by @Christopher2222 ,  my question is: 

is there a simple way to sort primarily by one column, but if two elements possess identical values, then using a second column to determine the order? For example, what if we wanted to sort the flashlight dataframe primarily by "B-type" but use a subsort by "Minutes". 

I wrote a function which used recursion. It worked fine for small dataframes, but was painfully slow with a multi-thousand element spreadsheet.

Even though I was using the thoughtful answer provided by a poster in a previous MaplePrimes question, I was unable to successfully place labels on a column graph.  I have reduced the problem to adding a plots:-setoptions call, of any type, before calling ColumnGraph:

The challenge for me is that for my work, several default plot parameters require changing including the default plot size which is too large. Hence my Maple initialization file includes calls to plots:-setoptions. Is this a bug in the ColumnGraph command and is there a work around that does not include removing the plots:-setoptions from my initialization file? Note: this problem occurs both in Maple 2019 and 2020. 

I have a string which includes characters from the extended ASCII character set. I simply want to print the string. Nothing fancy. Hence my question is: how does one print characters from the extended ASCII character set so that they show up as the characters and not a bunch of empty boxes?  (A technique for UTF-8  character printing would be a bonus.)   

<Edit> For example, in integers, my string could be:

s := [56, 72, 157, 38];

Hence there printing of s as a string should be a 4 character / bytes entity: 

printf("%s", convert(s, bytes));

In preparing to sample problems, I came across this difference in an output depending upon the input type: 2d Input vs. Maple Input. Is there a typo on my part?
