I am using VB express 2010 and I have the following problem: I would like to make a line chart of an array.For example: the daily mean temperatures (Temp(365)) and in the x-axis the date.Do I use the chart option of the toolbox? And how do I link this to my data? Or is it better to program everything myself? How do I start?

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.
