I first asked this question back in 2009 (PHPRunner 5.2) and was told that more charts were planned.
For engineering applications, the most useful chart is the X-Y scatter type. These have been supported by AnyChart for ages now but still not appeared in PHPRunner. Faithfully used this application and upgraded several times, including the latest version 10, but my patience is wearing a little thin now.
Please, please, can these be implemented sometime?
