Ok … ive already cycled through the different markers and sizes … I currently have the more usable for us chosen. I was hoping I could create a custom bitmap and using some light script replace one of the options currently available or add to the current list. Im hoping this might be a feature add in the future Thank you very much for your reply and your time on this ---

The Easy Chart and Chart, are both based on the JFreeChart component. > **[JFreeChart](https://www.jfree.org/jfreechart/)** > > The official home page of the JFreeChart project. It is possible to set a custom marker as the series shape. See here: [https://www.jfree.org/forum/viewtopic.php?t=116389](https://www.jfree.org/forum/viewtopic.php?t=116389) ---

Oh so I can set the custom marker to the series ? and if so , what kind of image does it have to be jpg, bmp, png ?? I was thinking you were saying id have to code actual placement point by point (hand rendering the chart in code) ---
