hello there,
I would like to create something simple using vb.net and stats like stock market where it shows a line going up and down.
I get new numbers between 9am and 12pm everyday on a text file line by line like this

>time - stock - price

1393021891|16012|101
1393021892|16013|102
1393021893|16014|103

so my question is does vb.net allow to have something like the image bellow, that shows the price and time when I mouse over?

There is nothing built-in to do that, since it is a specialized use of a chart, and .NET is conceived as a generic development environment.

There are however a lot of third party charting components available, in a great range of prices. Simply find one that does what you need at http://www.componentsource.com/relevance/index.html?q=chart+%2Enet.

Otherwise, you will have to devise a system built around the Graphics class in the Framework. It should not be too hard to draw the graph, but getting to react to the position of the mouse means a pixel hunt. It would be your job to record the location of the data on the chart, determine what pixel is moused over, and retrieve the appropriate data.

It's up to you to select what you need.

ComponentSource is a good provider of components. If it exists, they have it. They have been at it since the middle of the 90's and my past experience with them has been a pleasure as well for free stuff (they have some) as for high end components over $1000. As I told you in my last post, they have them in the whole price range. They are the Amazon of software components.

I never bought a chart component from them, so I have not suggestion to make. Just go there through the link in my last post and look. You can download demos or evaluation versions of most of the components they offer. The problem there is usually that there is so much choice that you can spend hours refining your choice.
