I 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 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.
My whole project is about reading data from textfile(the readings is separated by delimiters) and plotting out the graph. But somehow i am meetnig some problems as i think my method is wrong... It's something like this..what should i do?
Private Sub CreateChart()
'Create some dummy data
'Dim random As New Random()
'For pointIndex As Integer = 0 To 9
' Chart1.Series("Series1").Points.AddY(random.[Next](20, 100))
Dim h, g As String
Try
Dim lc As New StreamReader("C:Tempdatalogger" & date1.ToString & "int_ana_" + date1.ToString + ".txt")
Dim ff As String '= Label5.Text & ":00"
'Dim sr As String = lc.ReadToEnd
Dim line6 = lc.ReadLine
Do While Not line6 Is Nothing 'loop until end of file
If IsNumeric(line6.Chars(0)) Then
Dim fields5() = Split(line6, ";")
'Dim fields5() = Split(s.Substring(sr.IndexOf(ff)), ";")
h += fields5(0) + vbCr
g += fields5(3) + vbCr
End If
line6 = lc.ReadLine
Loop
Catch ex As Exception
End Try
For pointIndex As Double = 0.0 To 2.0
Chart1.Series("Series1").Points.AddXY(h, g)
Next
'line display chart
Chart1.Series("Series1").ChartType = SeriesChartType.Line
'set the bar width
Chart1.Series("Series1")("PointWidth") = "0.1"
'Show Data points labels
Chart1.Series("Series1").IsValueShownAsLabel = True
'Set data points label style
Chart1.Series("Series1")("BarLabelStyle") = "Center"
'Draw Chart as 3D Cyclinder
Chart1.Series("Series1")("DrawingStyle") = "Cylinder"
End Sub '****End of Graph
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?

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'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

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).
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.

Any body worked with MS Charting control for VS 2008.
I am using the chart control to displaying marks secured by students in different exams.
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.
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.
I'm using MS Chart Controls, i want to add a feature to my charts, im primarily using Bar charts. I will have a large numnber of Data points on my chart for example 20 bars etc, i want to limit the display to 10 so if there is more than 10 it will only show the last 10 bars and display a scrolling bar to scroll back and fort to see all the charts. I have the code to do this, and it works extremely well, only problem is. the code is in VB.NET I've converted it to C# and I am not getting any errors on page_load but my code doesnt seem to affect my chart in anyway, basically it doesnt work. Just wondering could some one have a look at my code and give me any pointers where i may have gone wrong or if anyone has ever got something similair to this working in c#. Im going to post both the VB.NET and the C#,

I am using a Chart Control, and I have 2 series. In my case 1 for month and 1 for year. The problem is when the chart control is displayed during run time for some reason the legend has 4 entries 1 says Mont, 1 says Year, 1 says Series 1, and 1 says series 2. My question is why are there 4 entries for the legend?

I am working with a chart control and on the Y axis i have numbers that fall between millions and billions.
The numbers on the axis themselves are not formatted and as such can be difficult to read. I wanted to know if there was a way for me to format the value that appears on the axis itself to be coma seperated?
here's what the Y axis looks like
600000000
300000000
100000000
numbers are just hard to read. How do i format them with coma's or even add a label saying (Millions) and then displaying only 100, 300, 600 etc
I can't figure out how to get the legend to populate all the "strReason" and get the correct percents to show for each column. This is where I'm at right now.

I have a DevExpress WebChart Control that binds to a DataTable. The chart control renders fine from the DataTable until I try to import data from a details view(i think the chart control renders before the detailsview?).
Here is three renderings.
Chart 1. just rendering from the datatable
Chart 2 The sqldatasource gets its para. from the values of two label controls to render the detailsview. The detailsview renders fine
Chart 3, the problem comes in when I try to extract the values from the DetailsView to populate the Chart, I loose the value. I am assuming the the datatable is built before the rendering of the detailsview? Lost at this point.
