Chart Object in Visual Basic 2010
Hello, I have an application that loads and runs through some financial records and records a balance and the number of transactions. It then charts the data to the chart object. It works fine and when the program runs to completion I can view the chart data. However if I close the chart and then re-open it, the chart shows no data and I have no idea why. I am not sure of the number of transactions so I have defined an array to hold these which increments by one each time the procedure is called. Code is below; the first procedure adds the balance after each transaction to the array, along with the transaction number (x,y coordinates). The second procedure displays the chart data when the "graph" button is clicked once the application has run. It works once, but only once, if the I close the chart and re-open it, there is no data to display?? Any help greatly appreciated Matt Private Sub Track_Balance() Array.Resize(current_balance, current_balance.Length + incBalanceArray) ' add some elements during runtime current_balance(incBalanceArray) = totalBalance Graph.Chart1.Series("Balance").Points.AddXY(totalTransactions, current_balance(incBalanceArray)) incBalanceArray = incBalanceArray + 1 End Sub Private Sub GraphToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GraphToolStripMenuItem.Click Graph.Visible = True Graph.Chart1.Series("Balance").ChartType = DataVisualization.Charting.SeriesChartType.Line Graph.Chart1.Series("Balance").Color = Color.DarkOrange Graph.Chart1.Visible = True End Sub
