Forms Data Controls :: Plotting A Chart Using Charting Control?

Mar 15, 2010

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.

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.

Forms Data Controls :: .net 4 Chart Control - Hide Labels In Pie Chart?

Apr 28, 2010

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?

Forms Data Controls :: Creating Stacked Bar Chart From VS2010 Chart Control (Documentation)

Nov 17, 2010

i'm trying to create a stacked bar chart on a vb web form using vs2010.My data source returns:

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.

Forms Data Controls :: Chart Control Tooltip On Pie Chart Not Updating On Partial Postback?

May 21, 2010

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).

Charting - Ms Chart Multiple Series X Value Mismatch?

Sep 3, 2010

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.

Forms Data Controls :: Charting: More Than 24hours On A Time-axis?

Jan 19, 2010

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.

Forms Data Controls :: Formatting Axis Of A Chart Control?

Jun 29, 2010

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

Forms Data Controls :: Binding DataTable To Chart Control?

Nov 19, 2010

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.
