The bar chart visualization is useful when trying to compare an indicator across multiple regions. It provides, for a specific year, both the value and uncertainty of an indicator.
Let's explore how our bar graph is built. First, let's start by our value marker. The figure below shows a regional estimate by sex. The blue and pink region representing male and females respectively. The thick black line represent the point estimate, and the top and bottom whiskers represents the end of the confidence interval. If your estimate is not stratified by sex, both sides will have a teal tint.
Here is a typical example of the bar chart page, in the bottom section, we will go though its feature clockwise starting from the title.
For more details on information contained in the title, see the Visualization Title help page.
On the top right, help section will lead you here, while the legend will remind you of the basic features like so:
At the bottom, is both the year slider selector, and the control bar. For more details, refer to these sections. Leftmost, you will find the current unit of the indicator. If no unit is shown, it means the indicator is dimensionless or "unitless".
Inside the plot area, at the top left you find a contextual panel showing specific details about the currently selected region. The selected region can be identified by its deep teal (as in the last figure). At the bottom of the draw area, you find the name for the selected sub-population (ex. Alberta or 5-10 years old). Hovering the corresponding column with your mouse will show the full name of the sub-population.
Our bar chart has one main constraint, it cannot show both Age and Geo dimensions. This is why the control bar will prevent you from asking for that configuration.
Finally, the dashed line at the middle of the plot is the "benchmark". At this moment, the benchmark value is the value for the whole population (ie. not stratified by age or geo).
Finally, yes we know our bar chart is, in fact, a type of box plot without interquartile range (IQR).
