I can not figure out how to get the chart to display the labels. When I try and add labels, the lines get messed up. Also, if I try and do multiple lines it does not always work out very well. I tried different ColumnLabels and they behave very strange as well. What I want is to be able to have several lines. Each with their own label. And also, I want to specify text for each point at the very bottom of the graph. Let me know what suggestions you have. [Code]
View 3 RepliesI have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?
View 1 RepliesUsing the System.Windows.Forms.DataVisualization.Charting objects/namespace, am having problems getting by chart to sort axis of dates properly.My data looks like this (dates in US format):
Product Quantity SaleDate
A -- 2 -- 5/1/2011
B -- 1 -- 5/1/2011
C -- 1 -- 1/1/2011
B -- 2 -- 2/1/2011
I'm creating a stacked column graph like this, where dv is a dataview of the datatable:
vb.net
chSales.DataBindCrossTable(dv, "Product", "SaleDate", "Quantity", "") chSales.AlignDataPointsByAxisLabel() For Each cs As Series In chSales.Series cs.ChartType = SeriesChartType.StackedColumn cs.YValueType = ChartValueType.Int32 cs.XValueType = ChartValueType.DateNext
So this produces a stacked column graph with 2 A's, 1 B in May 11, etc But the date order is Feb, Jan, May, regardless of how I sort the datatable provided to the chart.

I'm trying to present results on an aspx web page where a store procedure parameter is defined by a dropdown list control on the page. I have followed this guide from Microsoft and have my resultset presented in a DataGrid view. But I cannot seem to adapt it to present the resultset in a chart.
As you can see from my VB code below, I thought it would simply be a case of adapting the GridView databind to a Chart. I have tried various other options, and have successfully generated my data in a chart using a hard-coded parameter in an SQL statement on the ASP page. But when it comes to using the control, I get an empty chart.
Below is what I have so far.

View 15 RepliesI am using MS chart control .net 4 framework in Visual studio 2010 using Windows forms. I am having an issue with the scale of the primary x axis on a user input from a text box on a button click. I am also using both the primary and secondary y axes which work on a user input.
I have checked the settings for each axis and they all have the same settings. I don't see why both y axes work on the user input and the x does not.
The following is the code I am using:

Chart1.ChartAreas("Area1").AxisX.Minimum = Val(XPrimeMin.Text)

View 2 RepliesI currently have a chart that plots lines of a changing value every time it is called via a timer.
Everything is running as I expected and I am happy, but now I want to be able to press a [STOP] button which will stop the timer and stop the graph from updating, (which I have coded and is now working OK), BUT I then want the code under this [STOP] button to clear everything from the graph, so when I re-start the timer, the graph is cleared and starts plotting fresh points on a clean graph.
The problem I currently have is that when I press the [STOP] button and then press the [START] button, the new lines that get plotted are "added" to the existing lines that are already on the chart, instead of having a new "blank" chart, with no data on it.
So what I am really asking is does anyone know if it is possible to reset a chart clearing everything off it so it is ready to start displaying fresh data?
I was hoping it was something like: "Chart1.Clear" or something simple like that, but I can't seem to find anything that will do it.
For example, today is 05/11/2009, I have two text box.
Actually it means that whatever what date i choose within the current month, the two textbox will display the last three months date.
For Example, Current Month is November 2009 , Textbox 1 will show 01/08/2009, Textbox 2 will show 31/10/2009.
Another example is Current Month is January 2009, Textbox 1 will show 01/10/2009, Textbox 2 will show 31/12/2008.
May I know how the vb.net code should look like?
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:
[Code]...
I'm seeing a strange problem with the labels on the X axis of my charts. I've setup two chart areas and aligned them (which displays fine) and the user can manipulate the chart by selecting different date resolutions (Year, Month, Day, Week, Hour) and different time periods.
The issue I'm seeing is that if a user selects say Months as the date resolution the X axis label display is inconsistent. If a fairly broad range for the dates is selected the X axis displays absolutely fine but as the date range narrows the X axis starts to duplicate labels ( please see the attached images). The second Image had a date range of 1st of May to 1st of August and as you can see the labels are duplicated. This is my first go with the chart control so I could be missing something basic. [Code]

How do I dynamically add or remove a chart series on a WinForm. To date all my MS Charting experience has been dealing with ASP.Net charts with static sql select statment to a SQL Database. In the new project that I have been assigned I have different cities with different amounts of points that they want monitored. One city might have 3 an another might have 5 or 7 so I can't hard code the amount of series that I need. It needs to be set up so the amount of series can be flexible depending on the city selected and then display those points on the chart.
