improve bullet chart object formatting

Arnaud Villemain

Hello,

I suggest these improvements for the bullet chart object for Board 14.x:

1. provide ability to display a char title (e.g. taking the layout title) as it is possible for the cartesian chart.
2. provide ability to let the developer select the place where the label of the axis dimension is shown (currently it is only above the plot for horizontal plot):
   1. above or below the plot (vertical plot)
   2. left or right of the plot (horizontal plot)
3. let more place between Y-axis title and Y-axis values. Currently the text "number of…" is stuck with the value 40.
4. let the developer decide whether he wants to display the value of a serie or not. Currently it is not possible to display the serie's value.
5. the displayed color for "high treshold bar color" seems not correct. In my example, the target value is the highest value. All other values (actual and both tresholds 50% and 80%) are lower. Why does board show the color rgba(242, 242, 242, 1) in my example above the red line? He should show only the Plot background color (see the ligh-blue crosses in my screenshot below). Can this be corrected as well please?
6. provide ability to display and to hide a legend as it is possible for the cartesian chart. Currently, no legend can be shown.

As an example to illustrate what i mean, here is a bullet chart

• layout: thresholds are respectively 50% and 80% of the target value.
  
• colors (standard values, i did no change anything)
  
• bullet chart as is:
  
• the same with the above numbers referencing the suggested improvements :

Many thanks in advance.
