Hi First I new to jasper reports - so maybee my question is obvious but I can't find the solution. I'm using TIBCO Jaspersoft® Studio 6.6.0 - Visual Designer for JasperReports 6.6.0 for creating reports, and it works fine but I'm struggling with a simple Bar chart. On the range axis (y) I have numbers of calls and on the domain axis (x) I have the date of a month 1-10-2018 ...... 31-10-2018 - pretty simple, showing call per day :-) But I have a couple of issues regards the bars in the the chart. 1) Color of the bar, how can I make all the same colour - ex. black. They are all different colors based on the values. 2) How can I change the thickness of the bars, right now they are hair thin? Looking forward to hear from you :-) Regards Torben BTW does there exist a manuall that covers the xml for jasper reports?
