User (Legacy) Posted December 31, 2005 Report Posted December 31, 2005 Hi, Can you please tell me how to work with the AxisY AutoScale? I'm using a realtime chart and i set the AutoScale property to true but the Y axis does not seem to auto set the max value each time a new point reaches the current scale - this cause the new point to be out of the scale. In order to work around that i set the Max property value by myself each time i'm adding a new point. Can you please tell me what can be the problem ? Thanks
Software FX Posted January 2, 2006 Report Posted January 2, 2006 chart.AxisY.AutoScale is set to true by default, it gets set to false when you assign Min or Max. When AutoScale is set to true it will adjust the Min and Max to fit a value everytime a value is assigned. If this is not the behavior you are getting please attach code snippet or sample program that demonstrates the issue. -- Francisco Padron www.chartfx.com
User (Legacy) Posted January 3, 2006 Author Report Posted January 3, 2006 I didn´t assign Min or Max values to the AxisY - not from the deginer and not from the code. But still the y axis does not auto scale according to the data provided to it. Attached is the program sample. Thanks.

Software FX Posted January 3, 2006 Report Posted January 3, 2006 The key here is that you are using Real Time charts. The scale is NOT updated if the value is set between BeginAddData and EndAddData, if the scale is adjusted optimized redrawing of the chart can not be used, the whole chart will need to redraw. If you want to update the Min and Max in a Real-Time chart as data comes in you will need to adjust it using the API, notice that every time you update the Min and Max the whole chart will repaint not just the new points. -- Francisco Padron www.chartfx.com
