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.
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.
I am having a simple Azure cloud app(WebRole=ASP.Net MVC) which draws charts using ASP.Net Charting control. Chart RenderType = ImageMap Chart ImageLocation = "/Images/Chart_#SEQ(1000,1)" Number of app instances deployed on Windows Azure = 5 App contains a button which draws charts as per users parameters. When user clicks on this button, MVC action is called which provides necessary ViewData for drawing chart and returns a partial view which after getting rendered sends ImageMap and Image location to client.
When I try to draw charts from IE8 I always get the charts as per my parameters but when I simulataneously try to draw charts on FireFox sometimes I get wrong charts(wrong images). Is is due to roundrobin used - #SEQ(1000,1) or due to mutiple instances of my cloud app?
I have an MsChart with 6 series. The data is retrieved from MySQL database and every series has different number of elements.
The X axis is represented by date values (YYYY-MM). I am sorting data ASC on date from MySQL query but when i generate the chart i have the values (from left to right) : 2010-01 , 2011-04, 2013-04, 2011-04,2012-04.
I tried sorting data like this , for every series:
I have an ASP Chart (v4) which displays the data I need perfectly. I want it to show labels at the top of the data points and I am having some difficulty with it.
Here is my code that works for both series but does not display the labels:
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?
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.
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 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?
I am doing account creation process which is containing 5 forms/ screens. On screens user at any screen can click previous button and go to previous screen and change data (but sure it cannot be done on 1st screen, as there is no screen prior to 1st).
If I redirect user to previous screen all data is washed. I am even clearing form. For this I will have to fetch data back from db.
Can there be a way that I may not have to get data from db and data previous form may not be cleared and user can edit anything ?
I am getting a strange error over one site vs another. I have created a chart web site that works, but now I'm moving that code into an existing website. I'm getting this error (see title) and cannot figure out why. The references are the same and I have the using directives the same (as far as I can tell). I'm stumped.
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.DataVisualization.Charting; using System.Data.SqlClient; using System.Drawing; using System.Data;
...
Charting.Title vbTitle = new Charting.Title( ddlSchool.SelectedItem.Text.ToString() + " Logins per Hour" );
I need to pull data out for a chart and the following is what I have come up with. While it works I know there must be a more elegant way to get the same data in the same format.
I had a requirement to pass data between pages in my application.I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving.Following is the idea I was trying to use:
PageA.aspx:
[Code]....
In Page A Codebehind file I am creating following public properties of the inputs to access in Page B:
[Code].... In PageB.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageA.aspx" %>
[Code]....
In Page B Codebehind file I am creating following public properties for the inputs to access in Page C:
[Code]....
in PageC.aspx: using previouspage directive to access page A public properties
Postback is working fine from Page A to Page B, but when posting data from Page B to Page C, it is automatically redirecting to Page A.
I am not getting any kind of error or anything. page is simply redirecting to Page A. One reason as I understand is that when I post data from Page A to page B. Page A life cycle is executed and Page A becomes null.But when the data is posted to Page C. why the PreviousPage property is checked for Page A?
Which storage method should I use when using ASP.NET Charting Tools? I'm currently using memory, because it seems like the most straight-forward and easy to implement option. Is there any reasons I should be aware of why I should choose one of the other options? The charts generated will be useful only for an overview kind of purpose (checking to see if a data collection is following a certain pattern, as it is being built day by day), and this function won't be used frequently.
Trying to print an ASP.NET Charting control behind the scenes in my web app. I think it is a permissions issue with the printer as everything is ok up until the point where my code calls:
chart.Printing.Print(false); bool finished = false; while (!finished) { finished = File.Exists(settings.GetValue("statusfile")); // file which indicates document was printed System.Threading.Thread.Sleep(1000); }
At this point the page just freezes (or continues to load endlessly - infinite loop!) Understandably this is happening because I am 100% relying on the document being printed. I do intend to add a timeout, however, at the moment I am just trying to figure out why exactly the document is never being set to the printer!
I have given the account (which the AppPool is running under) permissions to all the relevant folders and even the pdf printer itself...Still nothing.
Am I missing something? Is there any issues with printing on the server side via ASP.NET? I have encountered some issues doing this via WindowsServices in the past not sure if it is a similar problem with ASP.NET websites.
Update
I updated the AppPool to give myself (admin) permissions and it is the same issue. So by the looks of things the job is never being sent to the printer. I can't seem to figure out why though...
Probably should have mentioned this in my original post....but I am invoking the printer through a referenced DLL, this code is not being called directly from my application (incase it matters). Also this runs fine on my Development machine which is running Windows 7 IIS7.0 where as the server is running Windows 2003 server with IIS6.0.
Update 2
I removed the while loop and just left in the chart.Printing.Print(false) line and turns out the document IS being sent to the printer. So the issue must be with the settings file not getting written which is why the loop never breaks out!
I have a report like page which displays a gridview and a chart created from .Web.UI.DataVisualization.Charting which I want to convert to pdf. Currently I am using iTextSharp which in my opinion is really great. I managed to create the table in the pdf but cannot find a way how to display the chart as well.
