I am pretty sure that my mistake is something very basic but I been straggling to pinpoint the problem by myself.Bellow is the code that I having problem with.
<toolkit:Chart HorizontalAlignment="Left" x:Name="chartLine" Margin="31,35,0,0" Title="Chart for test" VerticalAlignment="Top" Height="233" Width="309">

I cant even seem to start. i drag the chart icon into the ground and then the sqldatasource. tie them too together. and then im completely lost. i tried tieing x&y values with sum,customer name but they just arent working correctly
View 1 RepliesI have an arraylist that contains some values. (e.g. playerName). I also queried for values in the database (e.g. playerName, playerSales) and I need to match the playerName in the arraylist to the corresponding ones that I did a query from the database. (match those with the same playerName). From there, I need to create a bar graph with the respective playerName and their sales (playerSales).
A portion of the code is shown below:

The arraylist I mentioned was saved to a session to be used in another page. Is my code right? And how can I create the graph from the values?
I have a gridview on a web page as shown below
[Code]....
On checking the checkbox, the user will actually be selecting the products that he/she wants. The selected products will be stored in an arraylist by using a foreach loop through the gridview. The arraylist will then be saved to a session before being redirected to another page. (a button will be clicked after the selection of products to proceeed to another page)
On the redirected page, a bar graph needs to be generated based on the products selected previously and also the product sales (this is retrieved from the database).
How can I generate this bar graph without having to code the whole graph out?
I have a web page where a GridView will be shown with a column of different products and another column with checkboxes. Checking on the checkboxes will be equivalent to selecting the products. The selected products are saved to an arraylist. Then, the user has to click on a button located on the same page to analyze the selected products. On clicking the button, he/she will be directed to another page where a bar graph will be shown. The bar graph will be the result of having analyzed the products. How do I create the bar graph where the products are taken from the arraylist but I can make use of the datasource within the chart control to retrieve more detailed info(such as product sales) from the database, taking into account the products from the arraylist?

View 2 RepliesOn my X Axis, I have months. The chart shows up to 11 points, i.e. Jan - Nov of the same year, but when I add 12 points (Jan - Dec), it will do an auto label thing and change the interval for every 4 months.
How can I change the graph so that it shows 12 months before it does the auto labels?

View 1 RepliesI am trying to find duration of an mp4 file using direct show component of windows using the Dotnet wrapper(directShow-lib 2005). But the method i used was GetDuration of IMediaSeeking interface. But this returns zero as duration.After searching i found the following statement:"It doesn't matter whether it's in a container or not, it only matters whether you have a parser/reader for it. There is no stock DirectShow parser to read raw H.264 files and no third-party one I can think of. Also, whether IMediaSeeking would work with such a raw file is implementation-dependent. Last, most H.264-related filters use MPEG2Video or
VideoInfo2 and neither works with MediaDet, so you would have to build the graph yourself."
I am building a web application using sql server reporting services. As part of my application, I present the report onwards to the end user using the report viewer control.
The reports that I have created are mostly very squeezed. That means that I have several graphs on the same single report.
What I want to do, is give the user the ability to focus on a single report. I've created the appropriate client side code, though now I am faced with a rather tedious problem. The image that the report reviewer renders is relatively small (as I needed to fit several graphs on the same single report). when I try enlarging the graph's image on the client side, it gets stretched. The image is rendered small!
How can I instruct SSRS to create a bigger image of the graph? Can I specify anything in the underlying querystring?

This seems like it should be extremely simple. I have a list of x,y cords in SQL table that I am pulling out into a reader. I am then trying to bind my points to a point (have to use it since I can't find scatter) chart control.
Chart1.Series("Series1").Points.Databind(myReader, "Xpos", "Ypos", "Tooltip=CName")
Where Xpos = the x cord column and Ypos = the y cord column.The chart generates but my problem is that I am getting multiple x values that are the same. For example I have (67, 45) and (67,54).I would think there would be one x value for 67 with the two points on it, at 45 and at 54.Instead I am getting 2 x values listed, both for 67, one with 45 and one with 54.
Just as a test I listed these values in excel (in 2 columns) and did a scatter plot and it generated what I expected (2 items plotted on the same x value, one above the other. Is there a setting I am missing or does the chart control "Point" not have this capability.

how to show data in bar graph format in asp.net.
View 3 Repliesi want to show report in graphical formate of data which is stored in sql server.
View 1 RepliesWe've worked out some of the tasks on our website can be efficiently solved by maintaining the data using a graph structure. But we don't have much of an idea about how the graph is best persisted. Further we want to write and read simultaneously in an efficient manner in out asp.net app so it needs to handle multiple threads. It doesn't need to be super fast but it needs to be scalable to handle potentially millions of nodes.
I don't want to hack my own system and have heard of Neo4j. Lots of Java developers seem to recommend it to one another. Obviously I'm on the .Net platform and prefer to not have to switch.
What are the available options, particularly on the .Net platform?
I have this requirement of fetching facebook user information like friends count and other basic information and integrate to our website.
I currently use facebook graph to ask user to authorise, fetch information and store in my database.
When their say, friend count changes how do I update my database without asking user to trigger it manually.
Is there a special permission where i can fetch user data when he/she isnt logged in.
I have seen this somewhere but not sure of the permission.
Or does facebook have any feature of publishing information on subscription ?
We're thinking of making use of the Facebook Live Stream social plugin for our site (example here), but I wanted to know if it was possible to access this data via the Graph API?
