The above parameters can alternatively be indicated in this way (one of the two methods is mandatory):
<x> Starting X coordinate (upper/left corner)
<y> Starting Y coordinate (upper/left corner)
<width> Width of the chart from the starting X coordinate
<height> Height of the graph starting from the starting Y coordinate

Parameters that define the appearance of the graph:
<style> (string) Chart style. Possible values:
line : Draw a line chart
area : Draw an area chart
<title> Chart title
<legend> Optional chart legend (if defined)
<maxValue> (numeric, float) Chart max value user for top Y scale. Set 0 for autoscale.

= (identical)
> (greater than)
< (less than)
>= (greater than or equal to)
<= (less than or equal to)
!= (not equal to)
Examples of expressions using placeholders/constants:
{data_set.doc_type}=1
{data_set.level}>={MIN_LEVEL}
