java - JFreechart XYline connect with database -


I created a graph with a connection to the database as follows: 

  string s = jTSensor. GetText (); String query = "select date, dual_points from records where id sensor like '+++"; "; JDBCCategory Dataset dataset = new JDBCCategoryDataset (CriaConexaokgetConexao (), query); Geoffrey chart chart = Chartfractorkkraditlain chart (" Records "," date "," Dew Point ", datasets, Plotoriatteshnkoartisiel, false, true, truth); time renderer renderer = nULL; category plot Plot = null; renderer = new Barrenderr (); Chartfrem frame = new Chartfrem ( "Records" chart); FrameksetVisible (right); frame.setSize (400,650); < / Code>

But to show only one These returns. I believe that the pursuit of other data in the database and the results show possible with other lines, but I'm not successful. Can someone help me please

Greetings < / p>

Watch createXYLineChart . already for database access one is JDBCXYDataset . XYDataset supports a series of data, while category datasets You are not using (as far as I know).

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
