The following examples show how to use bar plots to visualize distributions or histograms.
The following code shows the simplest usage of a bar plot. In this
example, the bars will be drawn with a fixed
graphical width according to the
thickness property. This means that the bar width is
independent of the x-axis
By specifying a
width in the respective
property, you can use a fixed bar width with respect to the
respective axis instead of the screen.
The following example demonstrates the difference: The width of the
bars in the left graph is specified as
thickness of the
KontrastBars object. In
the right graph, the
width within the data property is
specified. You'll see the difference clearly if you zoom in or out
of the horizontal axis using the mouse wheel or a touch gesture.
Example with error bars
You can also add error bars to bar plots. Please refer to Example: Error bars for details.
Example with custom bin edges
By specifying the data property
edge you can use bars
with non-uniform widths.
Using a variable base value
You can change the start position of the bars by specifying the
baseValue. The value can be either a number or a
numeric array like in the following example:
Using a color axis
It may be useful to color the bars according to their value. For this you can utilize a color axis.
