User (Legacy) Posted June 12, 2006 Report Share Posted June 12, 2006 I'm wondering what would be the right approach to extend ChartFX graph of a particular type with my own class. What if I need to draw an object (a line for example) on the canvas of the graph? Is there anyway I can override certain methods? An example would be much appreciated...

Software FX Posted June 12, 2006 Report Share Posted June 12, 2006 The chart control is complex containing several controls in it. To draw a line in the chart canvas you have 2 options: 1) Recommended. Use the annotation extensions (included with the product). For more information please refer to the programmer's guide, under "Chart FX Extensions - Chart FX Annotations". 2) Use the PrePaint / PostPaint events. This approach only works if you are generating an image. -- Francisco Padron www.chartfx.com Link to comment Share on other sites More sharing options...
User (Legacy) Posted June 16, 2006 Author Report Share Posted June 16, 2006 Are certain classes unavailable in the trial version? It seems that I have the same problem I had with Print command, I don´t see Annotations class! I´m confused...
