Forms Data Controls :: Pie Chart Size In Charting / Using MS Chart Control (3.5)?
Aug 12, 2010
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 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 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.
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).
I 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.
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.
im trying to create simple pie chart using the MS Chart controls. When my pie chart gets rendered in the browser i get padding around the pie chart that i cant get rid of. i would like the pie chart to sit up against the edge of the image with no padding or margin. in my code below the padding is highlighted in blue. i.e Chart1.BackColor = System.Drawing.Color.Blue;
<script type="text/C#" runat="server"> protected void Page_Load(object sender, EventArgs e) { //Set the chart type Chart1.Series["Series1"].ChartType = SeriesChartType.Pie; //add points Chart1.Series["Series1"].Points.AddY(12); Chart1.Series["Series1"].Points.AddY(45); Chart1.Series["Series1"].Points.AddY(67); //set back color of chart object Chart1.BackColor = System.Drawing.Color.Blue; //set back color of chart area Chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.Green; } </script> <asp:Chart ID="Chart1" runat="server"> <Series> <asp:Series Name="Series1" ChartType="Pie"> </asp:Series> </Series> <ChartAreas> <asp:ChartArea Name="ChartArea1"> </asp:ChartArea> </ChartAreas> </asp:Chart>
I am having a requirement, where I need to have a pie-chart, i need text around pie-chart , the text should be a hyperlink. Ex: we have 3 three fields A,B,C. A's ratio is 30%, B's ratio is 40%, c's ratio is 30% So pie chart gets divided into 3 parts, outside the graph , we should get the label A(in A's area only), when we point on , tool tip should say "A's ratio is 30 %'. I am working in .Net 3.5, VS 2008, using MS chart control(added explicitly by executing MSChart.exe.
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 using the Chart control unbound and binding data to it at run time. It is a bar chart. When it is displayed after applying the data the X axis is drawn vertically and the y axis is drawn horizontally. I want the opposite but cannot find how to change the orientation.
I have a Bar Chart being driven by the user search criteria. Is it possible to make it so they can click on the bars, or label of bar, and have it taken them to another page to see more details?
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.
Im building an investment illustration which takes a users initial investment of say £1000 then an investment term of say 10 years. I then do some calcultations on the server and return a datatable something like the following;
YEAR_NO - RETURN_AMOUNT
0 1000
1 1098.11
... ...
... ...
9 2319.70
10 2547.45
[Code]....
My 'Y' axis is the monetary and 'X' is the term, the problem i have is the line starts to draw from year 1 instead of flush up against the 'Y' axis at year 0 & £1000.
