JDBCXYDataSet - Not enough valid columns where generated

[venkata]

Hi,

I am using JDBCXYDataset, I am accessing a column, which has float variables as values.
But JDBCXYDataset is showing the error - Not enough valid columns where generated by query.

How can I resolve this?

Thanks.

The javadoc contains the following

The sql query must return at least two columns. The first column will be the x-axis and remaining columns y-axis values.

Is your query returning at least 2 colummns?

Thank you.
My query was returning only one column.
Now its working, Thank you.

And how can I change the date on x-axis.
My x-axis is date time stamp from database.

Thanks.
