I want to associate date and time to x axis of mschart, but only date is shown on x axis and time is invisible.What's problem?
program :Public Sub drawChart(ByVal data() As Double, ByVal AxiX() As Date, ByVal i As Integer)
Dim numOfData As Integer = data.Count

in runtime I can see that X-axis limits of my chart (minimum and maximum) are automatically changed as I insert points. That's nice. So I came to an idea to change that minimum and maximum values. It worked. But as soon as I wanted to return (at runtime) to auto I came across some problems. First I discovered that when auto scaling is activated this values are:

I'm importing some data from MySQL into a VB.NET application with .NET charts. At the moment, the chart is plotting points by date, which means that when you zoom in, each major tick mark simply displays the date.It would be better to change these dates to times (hours) when one zooms in.Presumably there's a parameter to do this, but I can't find it.
View 1 RepliesI have a windows forms project in VS2010 with a simple line chart.The data is dynamic and always ranging between 1.4000 and 1.5000.I want the Y axis's gridlines/labels to always be displayed on every #.##20 data point, as in: [code] So I tried the Interval property for the axis gridlines/ labels, setting it to 0.002, and the result was that the gridlines/labels were displayed every 0.0020 points, like for example this: [code]
but not on 0.0020 points too as shown previously.
I have used MSChart control and created line graph. when i move my mouse over the graph, i want to display X-axis value and Y-axis value in another label above the graph.
View 2 Repliesi'm having a problem with AxisX interval labels. I want my AxisX length to be exactly one minute and labels showing every 5 second. So it should be 12 labels all the time. But after that minute passes, I'm getting 13th, than 14th label and so on.

MS released the new MSChart for .net 3.5 sp1. I'm trying to get the hang of it in VS2008. One big issue I have is that if I have no data plotted the chart area axis's aren't drawn. Does anyone know a way around that? That seems like a pretty basic/common issue.
View 6 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 am in the process of automating a PowerPoint presentation that shows graphs that evaluate the Metrics of the organization. I have successfully created the graphs, with one exception. The dates I submit to be used in the X axis always changes format once it gets into the PPT presentation. The graph template that I clear and write over has the date format as "Jan-07". The new date data is now being written as "7-Jan". I tried submitting the data as a string, but no matter which way I formatted it ("January 2007, Jan 07, 07 Jan, etc") it would always change it to "7-Jan". Have any of you encountered this problem? Do you know how I can change the formats of dates in a PowerPoint MSGraph that is automated through VB.Net?

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
I am using VB 2008 and want to record a start date and time and then the stop date and time in a rich text box, i can get the start time into the box but so far can only stop the time instead of 2 seperate times, what i have is a drop down box with a list of computers 1-10 i was trying to get it so you picked a certain computer and that went into the text box then you started the timer and that was recorded, finally you stopped the timer and that was recorded but as i am a total newbie it does not work

I have a P/L chart which has a left scale (Y axis) which starts from a negative value. I want to format the axis labels (the major tick mark labels) so that the negative ones are red.
Something like;
If cht.ChartAreas(chtarea).AxisX.MajorTickMark.Value < 0 Then
cht.ChartAreas(chtarea).AxisY.LabelStyle.Font = New Font("Verdana", 9.0F, FontStyle.Bold, Color.Red)
[Code]....
Of course that doesn't work since MajorTickMark doesn't have a value property. How does one make this work?

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
I am having some major problems with the code in VBA and recording a macro didn't get me anywhere nor is the VBA help file. I have to have it so that I can input a values for the x axis rotation and the y axis rotation so that my 3d surface graph will rotate whatever values I input, the 3d surface graph will rotate those degrees. I also have to have a method for having the default rotation. I was also wondering how to put scroll bars for the x and y rotation. The only other thing I am having trouble with is having an input to check box for right angle axes. So far I have two cells for entering the x rotation value and the y rotation value. I also already have my 3d surface graph.
View 3 RepliesI have the smallest dataset in the world that simply consists of a month (text) and and amount. I want to produce a chart showing the month along the y-axis and the value up the x-axis. How do I do it? I have dragged the chart control onto the report page and populated the dataset. The chart shows but nothing like what I would expect. Just to make it simple I populated the dataset with an amount equivalent to the month number so it should show as 1 in January, 2 in Feb etc...However no matter where I drag the dataset's column names I don't get what I want. Where am I going wrong?
I use this simple loop to populate the dataset:
dsSales.Tables("Sales").Clear()
For i As Integer = 1 To 12
dsSales.Tables("Sales").Rows.Add(MonthName(i), i)
Next
ReportViewer1.RefreshReport()

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet
Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

2: Put a DateTimePicker in the GroupBox
3: Put TextBoxs in the GroupBox
4: Changed the DateTimePicker to look like this:
A)Checked - False
B)Allow Drop - True
I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.
