|
|
* arrangement :: How should I arrange the query results? 'horizontal' or 'vertical'
|
|
* chart :: Show a chart? 'none', 'bar', 'pie'
|
|
* donut :: Only applies to 'pie' charts. Punches a hole in the chart for some reason
|
|
* tilt :: Only 'pie' charts. Janky 3D effect. Looks terrible 90% of the time.
|
|
* lables :: Only 'pie' charts. Labels on the pie?
