chartlabelissue

as can see code, theming chart using xml, have not found looks might positioning of labels.

it's not of issue on above chart, when displaying more 2 fields, labels overlap:

chartoverlappinglables

does know how change position of labels? bonus points why chart titles appearing fuzzy? :)

use custom property pielabelstyle avoid overlapping. fuzzy title, there's garbage in theme. clean up. see below:

string mytheme = @"<chart>                 <chartareas>                     <chartarea name=""default"">                     </chartarea>                 </chartareas>                 <series>                     <series name=""default"" customproperties=""pielabelstyle = outside"" label=""very long label (#val)""></series>                 </series>                 <titles>                     <title name=""default""></title>                 </titles>             </chart>";
