Mar 15, 2010I am plotting a chart using charting control. The x-values are text values and y values are date values.

Forms Data Controls :: Charting: More Than 24hours On A Time-axis?
Jan 19, 2010I am making a chart on a asp.net page (visual studio 2010). I am "summing" time. As long as the sum is not more than 24hours, all goes well. But if the sum is bigger than 24hours, then I get a "Not a legal Oleaut date" error.
This is my code (simplified) :
Chart1.DataBindCrossTable(_dataset._table.AsEnumerable(), "factor",
"week",
"time",
"");
Chart1.Series[0].YValueType =
ChartValueType.Time;
duurhhmm is a DateTime field. "factor" and "week" are my groupings for the x-axis.
first question : what to do about the "not a legal oleaut date" ?
second question : on the axis I see 00:00,06:00, 12:00,18:00 and then again 00:00,06:00, etc... But I would like to have 24:00, 30:00.
Forms Data Controls :: Unrecognized Namespace System.Web.UI.DataVisualization.Charting?
Feb 10, 2011I'm getting a warning in my page directives saying that this namespaceystem.Web.UI.DataVisualization.Charting isn't found. I went to add a reference to the project so I could import the namespace and this namespace does not exist in the .NET tab. What do I need to do to get this working? Also, even if I add this to my Global Assembly Cache, that won't do anything for the web host web server that my website is publically on.Any guidance on this? How to get it on my local machine as well as understanding that it'll work on the actual web server?
View 5 RepliesForms Data Controls :: Pie Chart Size In Charting / Using MS Chart Control (3.5)?
Aug 12, 2010I am using MS Chart control (3.5), and have a requirement where I need to display 2 pie charts. The datapoints for the pie charts is set programatically. My doubts are as follows:
1. Can I display both the pie charts in a single chart control and area, or do I have to use two controls? (Currently I am using two controls)
2. How can I maintain the same size for both the pie charts? This is my main concern, since the pie sizes keep changing, depending on the number of datapoints. I tried using custom properties like "MinimumRelativePieSize", but it's not working.

Charting - Ms Chart Multiple Series X Value Mismatch?
Sep 3, 2010I'm currently developing a website that shows multiple charts that I build using data from SQL tables. I've used and followed Scott Mitchell's tutorial [URL] and K. Scott Allen's ChartBuilder class [URL] and all works well.
However when have two series that I want to show on the same Chart, if one set of data does not have all of the X values the other series does, the chart blindly puts all the data on, ignoring trying to match the X values of the other series, therefore mismatching the X values when the chart is shown.
I know that I can fiddle the data so that both sets of data have the same X values, however I'm trying to make the class handle anomalies in the data so that I don't have to worry too much about the data.
Memory - File Or Session For Charting Tools
Aug 16, 2010Which storage method should I use when using ASP.NET Charting Tools? I'm currently using memory, because it seems like the most straight-forward and easy to implement option. Is there any reasons I should be aware of why I should choose one of the other options? The charts generated will be useful only for an overview kind of purpose (checking to see if a data collection is following a certain pattern, as it is being built day by day), and this function won't be used frequently.
View 1 RepliesMVC - Unable To Print Charting Control On Server?
Feb 9, 2010Trying to print an ASP.NET Charting control behind the scenes in my web app. I think it is a permissions issue with the printer as everything is ok up until the point where my code calls:
chart.Printing.Print(false);
bool finished = false;
while (!finished)
{
finished = File.Exists(settings.GetValue("statusfile")); // file which indicates document was printed
System.Threading.Thread.Sleep(1000);
}
At this point the page just freezes (or continues to load endlessly - infinite loop!) Understandably this is happening because I am 100% relying on the document being printed. I do intend to add a timeout, however, at the moment I am just trying to figure out why exactly the document is never being set to the printer!
I have given the account (which the AppPool is running under) permissions to all the relevant folders and even the pdf printer itself...Still nothing.
Am I missing something? Is there any issues with printing on the server side via ASP.NET? I have encountered some issues doing this via WindowsServices in the past not sure if it is a similar problem with ASP.NET websites.
Update
I updated the AppPool to give myself (admin) permissions and it is the same issue. So by the looks of things the job is never being sent to the printer. I can't seem to figure out why though...
Probably should have mentioned this in my original post....but I am invoking the printer through a referenced DLL, this code is not being called directly from my application (incase it matters). Also this runs fine on my Development machine which is running Windows 7 IIS7.0 where as the server is running Windows 2003 server with IIS6.0.
Update 2
I removed the while loop and just left in the chart.Printing.Print(false) line and turns out the document IS being sent to the printer. So the issue must be with the settings file not getting written which is why the loop never breaks out!

#SEQ Keyword - Charting Control With Multiple Azure Cloud Application Instances
Feb 27, 2010I am having a simple Azure cloud app(WebRole=ASP.Net MVC) which draws charts using ASP.Net Charting control. Chart RenderType = ImageMap Chart ImageLocation = "/Images/Chart_#SEQ(1000,1)" Number of app instances deployed on Windows Azure = 5 App contains a button which draws charts as per users parameters. When user clicks on this button, MVC action is called which provides necessary ViewData for drawing chart and returns a partial view which after getting rendered sends ImageMap and Image location to client.
When I try to draw charts from IE8 I always get the charts as per my parameters but when I simulataneously try to draw charts on FireFox sometimes I get wrong charts(wrong images). Is is due to roundrobin used - #SEQ(1000,1) or due to mutiple instances of my cloud app?

View 4 RepliesForms Data Controls :: Find And Set DetailsView Controls In Empty Data Template In Gridview
Oct 31, 2010I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";
