Hi Forum 
 
I am creating HTML5 graphs. 
 
Please can you help me with these questions? 
 
(1) Do chart.width and chart.height give sizes in pixels? 
(2) If they do give sizes in pixels, why my graph is about .85 x the pixel size in the Y direction (is it a margin thing)? 
(3) Do options.legend.x and options.legend.y give the position in pixels? 
(4) Why my legend disappears when it looks like there's still space for the legend on the graph 
 
Thank you 

Jeremy Beta.

Dear Forum
 
It looks like the answer to (1) is that chart.width and chart.height do specify sizes in pixels.
 
I guess that the answer to (3) is that options.legend.x and options.legend.y give position in pixels.
 
I am still interested in answers to the other 2 questions!

Kind regards
 
JB.

Do you have any examples which illustrates the issues?
 
I'm assuming you're using commercial BIRT. What version? The HTML5 charts are based on HighCharts. There might be out of the box settings (e.g. margins) that were overridden in our implementation of HighCharts' packagin. 
 
You can overwrite the behavior using the chart script within the HTML5 report item. If need be, it is possible to even overwrite our implementation in the html5charts.js.
