View 3 RepliesI have an issue in using dot net chart control. In chart last column is not completely shown which give bad appearance and on right side of chart it looks like TickMark are enabled. I set MajorTickMark of AxisY2 disabled but still tick marks on right side.

View 1 RepliesI have a drop downlist,and next to it there is an MS bar chart.i want to change the datate of the MS chart ,once the user selects another year from the dropdownlist.
When the page loads ,the chart displays the default year(2011) and it works.The problem is that is does not change the data when you select another year from the dropdownlist.
Am I going mad/blind? Probably a combination of the two.
How does one go about removing the data labels from a pie chart with the new chart control in .net 4?
I can get these to display as tooltips absolutely fine, but ultiamtely I'd like the labels not to be present as it looks rather busy.
I've searched previous answers and seen code behind resolutions but surely there must be some sort of code infront option to turn these labels off?
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.
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.
I started using the awesome chart controls with my asp.net apps recently and so far they've been nothing short of breath taking. Right now I have a weird problem, on the first load of my page, the chart control appears correctly and the tooltip is correct, however, when I update it with new data, the chart displays correctly, but the tooltips are for the previous set of data.
I hope this makes sense. The first time I load the chart, the pie chart segments and tooltips are correct, after a partial postback (to get the new data), the pie chart segments are correct but the tooltips are for the previous data set.
Basically once the tooltips are set the first time, they can't be updated after that without a full page postback.
Here's how I set the tooltip:
[Code]....
Anyone else noticed this behaviour and have a work around?
Currently my only workaround is to check for a partial postback and not render the tooltip, which I'd rather not do as the tooltip display actual statistical data as opposed to the pie itself (which uses percentages).
Does anyone know how to explode a certain section of the piechart, which is part of microsoft chart controls?

So each column in my datasource need to represented by a row in the graph. and the contents of the stacked bars should be the values in the fields. how to set up the series in the chart object to reflect this?

View 1 RepliesIn my web forms application I have a site.master page with an update panel (Java Script ToolKit). Inside the update panel I have a survey and a columns chart to show its results. The chart properties are
visible = false
ImageStorageMode = UseImageLocation
RenderType = ImageTag
When the user votes, his/her vote is stored in a sql server table The chart is rebound to its data source
The chart visibility is set to true and the survey's questions are hidden. I've been trying to set the columns for the maximum and minimum values to a different color using the code I found in "Samples Environment for Microsoft Chart Controls" [URL] under Working with Chart Data Data Manipulation Finding Data Points Find Maximum and Minimum Values:
[Code]....
I have not got the columns to change their color. I have put the code inside every event handler I could think of (after it failed to work inside the page load event handler): Inside the chart Init, load, and pre_render handlers. Inside the click event handler for the voting button (before and after I call the chart.DataBind() method). Inside the page pre_render handler. Inside the ToolKitScriptManager pre_render handler. I checked the code behind the environment samples. All, to no avail.
when i create a chart, it renders with lots of white space around the actual chart itself, especially below the legend. how can i adjust this?

View 3 RepliesIn the control Chart, I add few points, selected from the database:
var Diagram_1 = Razrez_D1.Series ["D1"];
sqlDA.SelectCommand.CommandType = CommandType.StoredProcedure;
sqlDA.SelectCommand.CommandText = "Razrez_D1";
sqlDA.SelectCommand.Parameters ["@ date1"]. Value = Session ["date1"]. ToString ();
sqlDA.SelectCommand.Parameters ["@ date2"]. Value = Session ["date2"]. ToString ();
sqlDA.Fill (dataSet1, "Razrez_D1");
sqlDA.SelectCommand.CommandType = CommandType.Text;
for (int i = 0; i <dataSet1.Razrez_D1.Rows.Count; i + +)
(
string name_s = dataSet1.Razrez_D1 [i]. Name.ToString ();
name_s = name_s.Substring (name_s.IndexOf ('№')). Trim ();
Diagram_1.Points.AddXY (name_s, dataSet1.Razrez_D1 [i]. Count);
Diagram_1.Points [i]. BorderColor = System.Drawing.Color.Black;;
Diagram_1.Points [i]. BorderWidth = 1;
if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Red;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> = 4 & & Convert.ToInt32
(dataSet1.Razrez_D1 [i]. count) <= 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Yellow;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count) <4)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Green;
)
)
The problem is that the points on the X axis are signed that way: first is not signed, second is signed, third is not signed etc How can I sigh all points?
I have an application that needs to read data from a view and do some extensive manipulation prior to delivering it to a chart control (without modifying the original data in the database). I have the chart control on the page, and in the code-behind I've built a dataset which I load and manipulate programmatically to have the table, columns and rows needed (no datareader involved) I'm having considerable trouble binding the chart to the 'in memory only' dataset. Chart Control;

Code-behind; The arrays arDate(), arPropBase(), arPropRisk() and arProject() are declared and loaded prior to this code. I am certain that the arrays do contain valid data - I have verified that while debugging

I have 2 MS Charts(OriginalChart, encryptedChart) which are working well. I spent hrs trying to set these charts so that they display the same AxisY value. Example, OriginalChart displaying max AxisY value 50 (this value may change depends on the data), I need the encryptedChart to display max AxisY value 50 (regardless of its data) as well, This would allow user to compare the differences in these chart more easily. Currently, my encryptedChart is showing 5 to 10 for the AxisY value. I tried most of the possibility to set below but no luck. Research on this also not much useful info (or I don't understand them.)
"encryptedChart.ChartAreas(0).AxisY.ScaleView.... = OriginalChart.ChartAreas(0).AxisY.ScaleView....."
Below's my HTML code fyi.

View 2 RepliesI want to create a chart with more than 50 000. Up-to-date I use the dotnetcharting-chart-library. But the problem is the time to load the chart. It needs more then 20 minutes. An unbelivable event.
I load the chart with the values directly from database. The database-query needs less than 10 seconds. The rest of time the chart was created.
So my question to you. Do anybody know a chart-library for ASP.NET C# to show more than 50 000 measurements in one diagramm in a realistic time for a webuser.
Is there a way to add a legend to the chart it creates? I have created a line chart and by default it has created different colors for the different y - axis data.
I would like a legend on the side that displays what data goes with which line color.
