Is there a way to draw a graph in real time. The excel file has one column with the time in sec.(x) and the other column is data(y). The examples with charts I've seen is about converting to a picture, then paste it to a picturebox.

View 1 RepliesI am having problems passing data from one form to another form opened from the first form.Here is my scenario: I have my start-up form. From this form I open a form by using the following:
[code]...
I use this because I want to be able to open multiple forms from the start-up form.Then from the PartyDetail form I open another form to display order details, like this:
[code]...
I want this order details form to be able to get a partyid variable from the party detail form.This works, but depending on the order that I open the forms the variables are incorrect Example:If I open the first PartyDetail form and then open the OrderDetail form, it works correctly. I can open as many PartyDetail and OrderDetail forms that I want and the variables are correct.But, say I open a PartyDetail form and then open another PartyDetail form and then open the OrderDetail form from the first opened PartyDetail form, it displays data based on the second opened PartyDetail form instead of the first. Basically, I want to be able to open multiple PartyDetail forms and then open OrderDetail forms based on whichever PartyDetail form it is opened from.Right now I am using Public Shared variables on the PartyDetail form and accessing this variable from the OrderDetail form. I suspect this is my main problem but don't know the best way to pass the variables from the PartyDetail form to the OrderDetail form.What would be the best way to do this?
Will any of the free light-weight charting libraries; ZedGraph or NPlot, be able to draw a simple graph similar to attached image (no waste of space, and with colored plot areas)? This plot will act much like the task manager "CPU Usage" plots, with update of last value every 500ms, but only making a new datapoint every 1 minute or so.
Or is this so extremely simple that it's better to hard-code it? What classes should I look into for this?
I have two values those are contiguously One is Time along x-axis and second is the CPU Usage in percentage along Y - Axis. I want to draw a continuous line Chart/graph what ever called.
