Bar
The Bar Plot is a bit special since it is handled in a Container of Bar objects which can't be modified easily. Thats why the Bar plot object has it's own event handler to schedule a complete reinstantiation of the Bar plot whenever a property changes. This causes overhead and should be noted before use.
Example
Bar {
id: bar
x: [1,2,3,4,5,6,7,8,9]
height: [1,2,3,4,5,6,7,8,9]
widths: [0.3, 0.5, 0.7, 0.3, 0.5, 0.7, 0.3, 0.5, 0.7]
bottoms: [0, 1, 2, 0, 1, 2, 0, 1, 2]
colors: ["red", "green", "blue", "red", "green", "blue", "red", "green", "blue"]
edgecolor: "white"
linewidth: 5
xerr: [0.1, 0.2, 0.3, 0.1, 0.2, 0.3, 0.1, 0.2, 0.3]
yerr: [0.1,0.2,0.3,0.1,0.2,0.3,0.1,0.2,0.3]
ecolor: "pink"
capsize: 3
alpha: 0.8
label: "bar"
}
