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.
Can Visual Studio 2008 Gridview control do grouping? And how?
View 1 RepliesI am using Chart control to loop through and fill from GridView and it works fine.
Code:
myProductSeries.Points.AddXY(GridView1.HeaderRow.Cells(i).Text.ToString, GridView1.Rows(0).Cells(i).Text.ToString)
My question: How would I do that using a DataTable instead, is that possible. Does DataTable have a "Header" like GridView so do I fill the X value?
Is this possible? To display a value in a legend. Here is my code:
[Code]....
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 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 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 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 5 RepliesI currently have 2 queries in a database that are the DataSource (determined by user selecting one from a DropDown) which is working fine, but now the client is asking for a view (a query) that displays both sets of data together. I have the query made and it's working, but with the GridView currently everything is mashed together with no indication which set of data any of it is. What I would like to do is if the "all" item is selected in the dropdown have the GridView put a line at the top that states the first set of data then a line in the middle when the records are showing the 2nd set of data. Anyone know of an easy way to do this?
The columns are pre-defined using the ItemTemplate:

I have the charting working very basic. I would like to learn how to use the control more fully. I find the system to be totally inadequate.

View 3 RepliesI am using the Chart control that is part of the newest version of ASP.NET. In this Chart, I have 3 Spline series. Each series consists of a nullable in array (int?[]). If the element in the array is a number, I wants it point plotted. However, in the case that the value is null, I do not want it plotted. Is there a way to do this? If so, how?
View 1 Repliesso I have 3 series that are created from Cross Table Data Bind. Unfortunately some of the points are missing. Is there an algorithm I can use to cycle through the datapoints for each series and insert empty points to the correct spots so that my data is displayed correctly?
View 2 RepliesI need to defining the Series parameters for an MS Chart.
Using the sample data below is it possible to set the X & Y value types for a graph with all days for the month on the X axis and the total number of visits for each day on the Y. Are MS Charts capable of auto generating the X axis based on the extents of the data dates as well a counting the daily instances?

I have 2 series in the same chartarea. Both contain values by year (x axis). The problem is if one series does not have data for a given year, the chart will display the first value in a series on the first tick mark whether it matches the xaxis label or not.
Example:
[Code]....
Notice the 2009 value for series1 appears in the first column and the Xaxis now has 2 2009 tick marks. How do I get the values to appear on the correct X axis marks?
Column Chart not showing both series when value is 1
I am having trouble displaying a stacked bar chart with a Y-Value of 1.
See the mark-up below:
The first Y-Value of the first series (the RED series) is 1. The first YValue of second series (the BLUE series) is also 1. The chart only shows the blue series. If I swap them around in the mark-up it only shows the red.
The last value (when X is 6) is 2 for both series. The charts will show both colors for the value of two. I would like this behavior when the value is 1.
[code]....
I've created a stacked bar chart - so there are multiple series in a line. The series display the value, but when the value is 0 I don't want the value to be displayed because if there are multiple 0 value is starts to look like 0|0|0|0 i.e. not very nice on the eyes. I'm wondering if there is a way i can say if the value of the series is 0 dont display the value.
