Forms Data Controls :: Showing 50 000 Of Measurements In Web-Chart?
Dec 22, 2010
I 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.
I have to code a chart which get his data of a PLC-control. The problem is that the PLC send every second a measurement to my program, so I have to refresh the chart every second. Via a timer-element of AJAX I can load the chart every second with new data, but I donīt know how I can make this asynchronous.
I want to have this:
The chart-Website should refresh the chart every second via the ajax-timer. The measurements which were used should stand in an array which is updated with the PLC-control-Function.
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.
I'm trying to put Google's BarChart and PieChart both the client side version, and i'm experiencing some problems with the labels over the pie and the labels on the left of the vertical axis (of the bar chart).
I checked the code a lot of times and it seems to be like that you can see in the examples.I've tried the same page on Firefox and Chrome and it shows the labels without problems.If i try the examples on IE8 the labels are shown but not in my page.Sincerely I've not any idea where to start to fix this thing.
We are building a financial web application which requires a real time chart. Initially an empty chart will be shown to the customer with X-Axis from 08:00 to 18:00 with a gap of 2 hours, i.e 6 points. The Y-axis should be adjusted based on the price between these timings. Now, from 08:00 the client(browser) will send a JSON/Ajax request to the server for every 15sec(configurable time) to fetch the latest price. And then, the price needs to be updated on chart based on the time.
I have seen some third party controls but really aren't successfull to satisfy this requirement. Telerik controls doesn't have client side access to the chart because it renders as an image.
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 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 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

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'm having problem with MS Chart chart type column. If there are only 9 bar in the chart like the following picture, then the axis-x label show up properly.
However, there are more than 9 bars bar the chart, the axis-x label wont show up properly, some of them just dissappear.
Here's my mark-up for the chart:
[code]....
I don't know it works with only 9 bars? Is there any way to make the chart work properly? Also, if possible, how to make each bar have different color.
I remember seeing an example explaining how you could setup the asp.net chart control to show two sets of data from different date ranges on the same chart, but I can't find it now that i need it.It showed sales for Jan, Feb Mar 2009 in one series and sales for Jan, Feb, Mar 2008 in another series and had the chart in 3D so that one series was in front of another.Does anyone know of such an example or have any pointers how to achieve it?
I want to create pie chart to Show the Percentage of students who have not paid fee, i am Getting the Record of all these students in GridView and also want to create pie chart.
I'm using an asp.net chart control to display a pie chart, image below.

I can't find the property (I assume there must be a property) to get rid of the whitespace surrounding the chart. Does anyone know how to? I feel like I've tried everything...
Explaination in detail I have a tree view control on left of my page and AjaxToolkit:TabContainer on the right,consisting of 9 tabs in it (I have developed individual controls and added to the tab panels). On selecting a value from the tree view control the I am refreshing the values inside all the tab panels. There is a method reload written on all the controls which are called on tree view click which sets the value of the selected tree item in properties in all the controls and also refreshs them. Its a big performance issue for sure which i need to improve on but that would come later. My problem
1. In the Main tab (ascx control) consists of asp:chart control which I am populating and it also consists of 2 buttons in which ModalPopupExtender would open up another 2 controls on button click within this control. Now on the tree view click I am calling the reload of Main Tab which internally called the reload function of these 2 controls also
On Tree view click
Maintab.reload { ModalPopupExtender1.reload ModalPopupExtender2.reload } Secondtab.reload Thirdtab.reload If I populate the asp.chartcontrol without reloading the ModalPopupExtender1.reload ModalPopupExtender2.reload it works great but when I call both ModalPopupExtender1.reload ModalPopupExtender2.reload it shows up and goes away.
Any thing i am missing on ? How to make chart control stay on the page and not vanish. I tried making it visible again. The main page contains a chart control which comes and goes away and does not stay only if i comment out the reloading of these usercontrols it stays visible with values on the main page else goes away.
2.Performance problem- I am not sure how to lazy load the content inside the tab panels so that controls should have the selected item for tree view click and can populate thereon.
3. This is how I call my user controls to reload on the treeview click from within the main page. PEGeneralInfoPortfolioProfiler1.PortfolioCode = strPortfolioCode; PEGeneralInfoPortfolioProfiler1.ReloadControl(1);
I'm trying to build a chart in my application which will act as a client for an ASP.NET 3.5 web service that I created. The error I get is as follows:
Series data points do not support values of type System.Data.DataViewManagerListItemTypeDescriptor only values of these types can be used: Double, Decimal, Single, int, long, uint, ulong, String, DateTime, short, ushort.
I've tried various ways to resolve this but can't. This error points at the chtStats.DataBind() line in the code below:
I am new to asp.net. I am suppose to continue a project. The previous person has created a line chart and I have to create a bar chart. However I do not know how to create a bar chart. Could u email me for the code as I realise that I can't upload the files.
I need to create the following stacked bar chart using the MS Chart control: [IMG]http://i54.tinypic.com/2d1ti05.jpg[/IMG]
My table structure is as follows:
PEStaffAssessmentID int PESubmissionID int Q1_ConfidentDelivering int Q2_ProfessionalAttitudes int Q3_LeadershipEffective int Q4_SupportedByPeers int Q5_AssistedInexperienced int Q6_ConfidentKnowing int Q7_AbleToTalk int Q8_CommunicationEffective int Q9_ConfidentSupporting int Q10_TeamShares int Q11_CareDeliveredSafely int Q12_MinimumMaintained int Q13_MeetOwnExpectations int Q14_SpendEnoughTime int Q15_ProvidePhysicalCare int Q16_ProvideEmotionalCare int Q17_SpiritualCare int Q18_ProvideCare int Q19_ManageWorkload int Q20_HighestStandardCare int Q21_MoraleLevel int Q22_RateCareReceived int
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?
