i create stackcolumn HTML5 chart in Jaspersoft Studio 5.5.0 and want to format yAxis labels and stackLabels on it. try many different cases, but it is fail. i have added such proprties as: yAxis.labels.format="$ {y}" yAxis.stackLabels.format="Totals: $ {total}" all examples from http://api.highcharts.com/highcharts. but on the chart i see only numbers without my additional options. where is truly worked examples? another problem that i can't use JavaScript function as Chart Properties.. Jasper Studio is working bad with them. i can add function in the window Chart Properties: chart.events.click="function(event) {alert ('x: '+event.xAxis[0].value +', y: '+event.yAxis[0].value);" but after running that report i see in HTML-source such row: JRDefaultHighchartsSettingService.setProperty(highchartsConfig_13456883_22_2115148971,'chart.events.click',"function(event) {alert ('x: '+event.xAxis[0].value +', y: '+event.yAxis[0].value);"); if i delete symbols " and then such code is working as i want.. it is very looks like the bug! very annoying bug.. fix it! and please help with format functionality.. thanks
