I observed that calling the method pixelValueForDataValue: returns an incorrect value if the axis is of type DateTime. Is there any other method of obtaining the x-coordinate of an SChartDataPoint object where the x-axis is of type SChartDateTimeAxis?
Sorry to hear that you are having problems with this method. There is no other way to retrieve this information via our API.
Would it be possible to send us an example of where this method returns an incorrect value (if you’d rather not post code here then you can send it to firstname.lastname@example.org)? Doing this will allow us to take a closer look into the reasons that this isn’t working as expected for you.
