I see three options here: 1) There was a user contribution to configure a global offset for highlight values, which was undocumented until about 10 minutes ago (so it is not yet visible in the online documentation). You can configure a relative movement for those labels, but not their exact position in the chart, like: $chart->options->highlightXOffset = -10; 2) You can render an additional axis (at any point in the chart), which itself consists of labels, and therefor renders an additional set of labels in the charting area. This feature is documented in the tutorial to some basic extend: http://ezcomponents.org/docs/api/trunk/introduction_Graph.html#additional-axis-markers 3) If you clearly know hot to render the labels in your case you can extend from the renderer you already use and overwrite the method drawDataHighlightText() to do what you think works best. This is most flexible solution, but requires to gain some insight in the rendering infrastructure. Afterwards you can use your custom renderer as simple as: $chart->renderer = new myRenderer(); Kind regards, Kore -- Mit freundlichen Grüßen / Med vennlig hilsen Kore Nordmann (GPG: 0xDDC70BBB) eZ Components Developer eZ systems Headquarters tel +49 (0) 231-9742-7750 | fax +49 (0) 231-9742-7751 k...@ez.no | eZ systems | ez.no
