User (Legacy) Posted September 25, 2003 Report Posted September 25, 2003 I just spent hours troubleshooting a 'No Data Available' error in ChartFX for .NET when data WAS available (and being sent to the chart). The problem was datatype: The datatype being returned from my stored procedure was of type VARCHAR2. ChartFX expected a numeric datatype. When I converted the datatype NUMBER, the 'No Data Available' annoynance went away. SoftwareFX: Could we get more descriptive error messages please? The moral of the story: If data IS being sent to your chart, but you still get a 'NO DATA AVAILABLE' error message, verify that the values are numeric values. J.

Software FX Posted September 26, 2003 Report Posted September 26, 2003 Only numbers can be plotted. When all columns come back as strings, the chart ends up with no data hence the message. I see your point that we could have thrown an exception or something when setting the data the problem with that is that we don't know if you are going to pass these values manually using the API. So I don't see a better way of helping you debug your program here. -- FP Software FX, Inc.
