I managed to get the graph to update by using the DataSource directly with EWparData (the data comoing directly from SQL)


Then I set the – each time the chart is opened

lineChart.DataSource = EWparData;


However the seriesGroups are not updated, even though new values are entered into them.


I am not sure if the entire seriesGroup class/lists needs to be recreated each time, or if there is an easier way.
