As you see above , we have more data in pie chart to plot and hence 3 DOTS appear at right bottom. Hence user cant see all the legends.Is it possible to have.say a tooltip on 3 DOTS so that when an user hovers,he sees entire / remaining legend list?
View 5 RepliesI am plotting a chart using charting control. The x-values are text values and y values are date values.
If there is same text multiple times, then the plotted chart has multiple bars of same value. I want the values for the same text to be on the same bar.
I am working on charts with ms chart 3.5 control my question is I have to display legends of pie charts in tabular form. Which will contain the color used for different points and x values and y values. I managed to show the colors and x values but not able to show the y values. I am giving the code also. Example of x and y values are:
xvalues- InCorrect YValue- 5
xvalues- Correct YValue- 10
xvalues- UnAttempted YValue- 15
Here is the code used to bind legend values.----
LegendCellColumn firstColumn = new LegendCellColumn();
firstColumn.ColumnType = LegendCellColumnType.SeriesSymbol;
firstColumn.HeaderText = "Color";
firstColumn.HeaderBackColor = Color.WhiteSmoke;
Chart1.Legends["Default"].CellColumns.Add(firstColumn);
// Add second cell column
LegendCellColumn secondColumn = new LegendCellColumn();
secondColumn.ColumnType = LegendCellColumnType.Text;
secondColumn.HeaderText = "Name";
secondColumn.Text = "#LEGENDTEXT";
secondColumn.HeaderBackColor = Color.White;
secondColumn.Alignment = System.Drawing.ContentAlignment.MiddleLeft;
Chart1.Legends["Default"].CellColumns.Add(secondColumn);
// Add header separator of type line
Chart1.Legends["Default"].HeaderSeparator = LegendSeparatorStyle.Line;
Chart1.Legends["Default"].HeaderSeparatorColor = Color.FromArgb(64, 64, 64, 64);
// Add item column separator of type line
Chart1.Legends["Default"].ItemColumnSeparator = LegendSeparatorStyle.Line;
Chart1.Legends["Default"].ItemColumnSeparatorColor = Color.FromArgb(64, 64, 64, 64);
// Set Min cell column attributes
LegendCellColumn minColumn = new LegendCellColumn();
minColumn.Alignment = System.Drawing.ContentAlignment.MiddleLeft;
minColumn.Text ="#TOTAL{N1}";
I want to show the individual value of each data point is there any idea how to show the Yvalue of each datapoints
minColumn.HeaderText = "Questions";
minColumn.Name = "Questions";
minColumn.HeaderBackColor = Color.WhiteSmoke;
Chart1.Legends["Default"].CellColumns.Add(minColumn);
I 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.
Is this possible? To display a value in a legend. Here is my code:

Series of the chart can be dynamically generated.
I am looking for a charting tool to generate charts in my ASP.Net page which will allow me to customize the charts to a great extent like changing the background of chart, specfying custom x and y axis and much more.Moreover, another major requirement is that the chart should be interactive enough. I would like to select data points on my chart, select a range of data points on charts by making a selction with mouse clicks and use these selections for further processing.
View 2 RepliesI 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.
I'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 7 RepliesTrying 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!
give a code snippet which will explain how to use Binary streaming render type in ASP.Net Charting controls using $.ajax call in ASP.Net MVC Framework. ?
Ajax call will look like this-->
$.ajax({
type: "POST",
url: "/DrawChart/" + drawingParamter1+ "/" + drawingParamter2,
dataType: someSuitableDataType,
error: function(error) {
},
success: function(html) {
}

I 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?

I have 3 columns of data that get returned from a stored procedure. Date, Error code,and Quantity. On one day we can have 8 different error codes, with different quantities.For example on the date of 18 Nov we had error code 101 = 24, error code 102 = 36, error code 103 = 4, etc. I am trying to display the different error codes in columnswith their quantity by date. There will be multiple columns for a given day because the error codes range from 101 -124. How can I display this? I currently have Just oneat a time being display based on which the end user picks.
If DS.Tables.Count > 0 AndAlso DS.Tables(0).Rows.Count > 0 Then
ErrorCodes.DataSource = DS
ErrorCodes.Series("Exceptions").XValueMember = "Error Date"
ErrorCodes.Series("Exceptions").IsValueShownAsLabel = True
ErrorCodes.Series("Exceptions").YValueMembers = "Total"

I'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.
Which 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.

How Can I use MultiView with Data List Control .... I want the Items in Data List Appear as Collapsed Views and let The User to Expend what he want so how can i handle that ?
View 1 Replies I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
