Hi , I am try to change default bar chart properties like font-family,fontSize , legends font size , labels font size etc. I added those properties in highcharts.js file in the path in local server path : C:Jaspersoftjasperreports-server-7.1.01apache-tomcatwebappsjasperserver-proscriptsbower_componentshighcharts-packhighcharts Those are working for canned reports (created in studio and deployed in the server). But it is not working for Adhoc reports created in the server. Could you please help me to solve this issue.
