You can label specific data points in a graph with additional text or even image to further describe the data presented in PHP chart. To do that, the non-renderer plugin, “pointLabels”, is required. This plugin places labels on the plot at the data point locations.
The last value in the data point array in a data series is used for the label by default. The following example uses HTML image for data points.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | $s1 = array( array(0, 300, '<img height="30px" width="30px" src="images/new.png"/>'), array(1, 150, '<img height="30px" width="30px" src="images/new.png"/>'), array(2, 35, '<img height="30px" width="30px" src="images/new.png"/>')); .... $pc->add_plugins(array('cursor','pointLabels','barRenderer','categoryAxisRenderer'),true); .... $pc->set_series_default(array( 'pointLabels'=> array( 'show'=> true, 'escapeHTML'=> false, 'ypadding'=> -15 ) )); |
