Generating new charting
To generate a new chart, click on 'Generate new chart'. This opens a menu to create a new chart. You can select the charting type, dimension (the category/field you want to analyse) and value (the actual value you are measuring, typically a number count or casualty count).
With a bar chart you can add a second dimension to the chart. For example. if you set the first dimension to week, and second to type you have single bars that are split by colours into incident types.
