Charts - Bar Charts Menu
To make a bar chart you create a bar object, then add it to the chart using
the add_element method.
There are a bunch of different bar objects which have different styles:
We can also have more than one bar at each X value:
on-show animation of the bar charts.
Y min = 100
You can set the bottom of the bar to have a Y position, useful for
Gantt charts and showing ranges.
Don't forget that all charts can have on click events
and can custonize the tooltip look and feel.
If you don't have a complete data set, you have null or missing data,
look at the null values page.
