im using Vs2010 to plot real time line chart. i have been looking for the section that allow me to set X and Y axis..
i jus couldn't find the place for me to set.
my Y axis is a double, min =0, max = 100 and my X axis, min =0, max = 300(seconds).
i'm trying to create a stacked bar chart on a vb web form using vs2010.My data source returns:
Error in Functionality Awaiting on Supplier
1IMT IssuesmActive6
IMT Issues,Awaiting on Supplier
2,IMT Issues,Awaiting on User 4
IMT Issues Closed 120
Login / Password Active
But I can't get this into a stacked chart. I know I must have to do quite a bit of work declaring what the series are and soforth, or having a different dataset but can't find any documentation on it.A link to some documentation or an example of a stacked chart from an sql datasource would be much appreciated.
We have a requirment to draw a graph (line or bar), where the data will be changed 40 to 50 times in second , we want to refresh data automatically.
Which chart component should we use for drawing graph and how do i make sure that the data will be refreshed very fast on the graph web page.
I would like to create a progress bar with real time updates on the different method calls that happen on a button click in asp.net 1.1. I have seen some examples but nothing that provides updates on the progress bar while the server side operation executes.
View 1 RepliesI have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.
My application work in this ways. I got a database collect data from 20 sensors. Database holds Temperature and DateTime data/Records from sensors. So i would like to make it whenever i view the chart, it will plot a line chart one by one according to the temperature and timestamp(DateTime). Which mean my X axis is a colleborate time on that particular date.I already design a in the way that the line chart will plot base on both dropdownlist, Sensor ID and Date. So it will work like whenever i select a Date or ID it will read the records from database table temperature.
View 9 RepliesI have a chart on a page and i call a dataset which sends the infomation to the chart this works fine and all the infomations is displayed fine. However my x axis is a time which is UTC time. Most of the people looking at the charts will be using EST is there anyway in which i can change the Xasis times to corespond with EST instead of UTC

View 3 RepliesI need to build a system which needs to show data on almost near real time basis from a MSMQ data source and this sould be showin in image with a circle as to where the incident occurs.
This is the description given.
The position of the Incident relative to the 123 mark is requested to be represented on a circular concentration diagram .
The algorithm will have to export the location of each incident relative to the 123 mark in polar coordinates (r,θ) and translate this position to the 'master image' coordinate system that will display Incident location.
I have two questions.
1. How can i show the data in an Image and also please point me to any material which might help me with the same.
2. How do i show almost real time data from a MSMQ data source and also how do i architect the same for performance.

View 1 RepliesGiven a Database that has a table Called [Bid Transactions], which contains records of all available auctions that are currently running on an ASP.net website .. something similar to Ebay.com, when the deadline of the auction passed, I should close that auction, Send a notification message to both the item owner and the bidding winner to inform them.
how should I keep track of all open auctions? how could I monitor all their ending time and update the Auction status to be "Closed" on Real-time basis? ..

(2) A back-end service that is running on the server and uses Threading ? .. I have no clear background about that solution.

It is doing it on new web.application and Tailspin Spyworks demo app. If I switch a new web.app from asp.net4 to asp.net3.5, all the controls display properly.
I've tried removing and re-installing VS2010 and had no changes.
It acts like something didn't get installed.
