GNUPLOT: boxplots variable line style/colors

I have multiple data files for which I want to draw a single figure. Each of the files contains a column with two variables: true and false. I would like to draw boxplot for each of these values such that they can be compared. Sample of data file is given below: 

0.6,true
0.7,true
0.5,false
0.4,true
..

I come up with following code:

plot inputFile1 using (1):($4):(0.3):3  title 'A' , \
inputFile2 using (3):($4):(0.3):3   title 'B'

This generated the following figure: enter image description here

However, I would like to customize it such that all the boxplots with "true" variable have one specific line style/color and boxplots with "false" variable have another specific line style/color. Furthermore, I would like to show in the title the shape of true and false, however, on x-xis, I want to have File A and B for each true,false pair.

Any help in this regard would be highly appreciated.

Thanks in anticipation.

With your current datafile, you would need to detect whether the second column contains true or false and act accordingly. However, I am not sure gnuplot can process strings from a datafile.

If you process your file and replace the true or false by 1 or 0, then you can adapt the following line:

plot [0:6] "+" using 0:($0/2.):(0.3):0:xtic((int($0)%2)==0?"true":"false") w errorb lc variable

Here the 4th number in the using list defines the colour, with $0 the colour changes for each line of the file, but if the colour number is in one column of your file then use that column. Replace the "+" by your file and the first two numbers in using by the parameters needed by your plotting style. The xtic command processes some column in the file (here the line number $0) and labels the x tic depending on the value (see help ternary).

Note that your MWE does not work as is, please amend it if you want a more precise answer.
