<x1> Starting X coordinate (upper/left corner)
<y1> Starting Y coordinate (upper/left corner)
<x2> Ending X coordinate (bottom/right corner)
<y2> Ending Y coordinate (bottom/right corner)

Parameters that define the appearance of the graph:
<minValue> (numeric, float) Chart min value
<maxValue> (numeric, float) Chart max value
<value> (numeric, float) Chart value to display
<border> Show or hide border. Possibile values:

= (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}
