I have a program that is supposed to display a line chart of some values Im reading in from an XML sheet. The function that reads the data into arrays works fine. When I try to graph the values, all I get is a flat line.

I can not figure out how to get the chart to display the labels. When I try and add labels, the lines get messed up. Also, if I try and do multiple lines it does not always work out very well. I tried different ColumnLabels and they behave very strange as well. What I want is to be able to have several lines. Each with their own label. And also, I want to specify text for each point at the very bottom of the graph. Let me know what suggestions you have. [Code]

How would i go about reading a file Line by Line that within that line The values are delimited by " Example of the data:
"bob" "cat" "1243"
"steve" dog" "6789"
I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _
Microsoft.VisualBasic.FileIO.TextFieldParser(My.Application.Info.DirectoryPath & "Records28112011.jd")
MyReader.TextFieldType = FileIO.FieldType.Delimited

I have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?

I just need my chart to load this log file and loop through it and populate my line chart.I am able to make a line chart and populate it from a text file but only in a long way. I first load all the data to 10 text boxes, then I split all the data into 40 other text boxes then I use that to populate the chart, There has to be a easier way of doing this. With my current way I can only load up 10 days of data.I would like to be able to load up 30 days of data or even a years worth (365 entry's).I am using visual basic 2008 with .NET Framework 4 Chart Controls.[code].....The Date has to be at the bottom of this chart (going left to right) and the numbers on the left side.

View 4 Repliesi have a dice program that will find the random numbers according to user input as regards dice and throws required. My problem is when i have to display all the values in a listbox but in a horizontal type, were if a value came out more than once it displays the number and a bar for each time it come out and also at the end show the count of the times the number came out, to have a better idea the final chart needs to be displayed in the following format in a listbox as in the long run the program needs to run in a web application, but i am writing and testing in a window form application, then i will transfer to web application and use session variables and timers to control the output and the graph.
