I 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 am busy with a routine that will draw a bar chart.The X-axis is from 0 -100, no problem. The problem is the Y-axis.it will range from 0 to whatever the highest y-value will be.
My problem is that the y-axis should still be divided into 10 intervals, and the lenght of my y-axis should be the same in my picture box.I am using an array to fill the values, chartdata (0-9). It gets 10 values from the program. the values are 0 -10, 11 -20,21-30....91-100 . here is the code. It is working, but my Y-axis is messed up. Printing the labels of the y-axis is a problem.
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint Dim chartData() As Single = {mark0, mark10, mark20, mark30, mark40, mark50, mark60, mark70, mark80, mark90}[code]......\vb
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 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.
i'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.
I have a database with testmarks of - lets say 30 students. I would like to print a distribution chart using Mschart. The values will be loaded into an array ChartData(30) The distribution chart X-axsis should range from 0 - 100 and the Y-axsis 0 to the average amount.... hopes it makes sence....
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 am having trouble in getting the coordinates of x-axis and y-axis in low level ouse hook...all I am getting is values in x-axis listbox and in y-axis listbox I am getting zeros......why? and my second problem is I am calling the setcursorpos function in a for loop because I want to automate mouse movements and clicks, but setcursorpos function is not working , maybe because I am getting the coordinates wrong.....here is my code

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.
I 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
look at the comments at the beginning of each class. Note, the period is rather small (100ms), and the process being triggered could occasionally take more than 100ms (in which case, the next thread trigger should be delayed ... two threads shoud never overlap). Also, the class will never be instantiated more than once.
I decided to whip up a simple stopwatch-esque timer for some needs of mine. Well after writing a very basic code for the timer to show seconds and milliseconds I see that the intervals are wrong[code]...
I have a piece of hardware that is controlled via USB.There are 8 LEDs on the output byte. One LED per bit.I like to toggle the outputs based on selection of checkboxes and given frequency entered in TextBox.I inserted 8 checkboxes to allow me to select the desired LEDs to be on.I select the checkboxes to select the required LEDs.The checkbox gives me the byte value. XORing the byte value with 255I can see them toggling very fast. I have a while loop to blink forever until I click on stop button.The stop makes the seq=false and this should stop the blinking but it keeps going.How can I insert desired delay of flashing frequency in my output routine?How can I stop on demand to change pattern without exiting the program.
I'm using the chart control that's built in to Visual Basic 2010.NET Service Pack 4.
I am creating a basic date time graph with time on the axis and, at the minute, random points between -20 and positive 20 on the y axis. At the minute I can set everything up perfectly. The only problem is that the label on the x axis is not a time, it's a number. To be precise, it's the XLabelInterval value. This value is a double, so the label on the x axis is also a double not a time. But that's only interval I am setting. I think, by default, because I am not setting any labels, it is just using that value as the label as well.[code]...
I want to upload data at regular intervals, for that I used windows service with timer. Now problem is when I start my service. Its showing System.IO.IOException error.
I've spent hours searching the internet on this, and found a bunch of posts with similar problems, but none of the solutions I saw have worked for me, so bear with me. I have an application that's a couple years old that has a form with a chart on it(using mschart). Worked on my old development machine, and most users. Eventually some users started letting me know that the chart wasn't working for them. The chart was a minor feature, and I was unable to reproduce the problem, so it kept getting pushed back.
I am working in windows xp sp3, I am using MS visual studio 2008 with vb.net, In my system i dont have AxMSchart20Lib,Mschart20Lib and Mschart.ocx. From where to download in microsoft site. give the microsoft download url.
I have created a windows service and I have two different timer variables in there. 1st one fires off every 5 seconds and then does whats it is required to do. The second one fires every 30 seconds.
I make sure that when the function are getting executed I disable both the timers and enable once the function is complete.My problem is my second longer (30 second ) timer never fires only the first one is firing. I had created this service 3 months ago and it was working fine till now. But now I do not see the timers work properly in a simple windows app i created to test their workings.
I want to change the color of the row in my mschart i used this code but it says, index out of bounds. im working this for a couple of days but find no solution. im very much great full if i will be helped.
[codes] AxMSChart1.RowCount = 5 AxMSChart1.Plot.SeriesCollection(1).DataPoints(1).Brush.FillColor.Set(250, 250, 250) 'error says index given is out bounds [/code]
How do I do the following with an MSChart?Set axes to x: [0 - 1000] and y: [0 - 1].Show the gridlines when chart has no points.Disable auto adjusting of gridlines.
Note: Setting Axis(X/Y).(Min/Max)imum seems to have no effect if a point exists inside the bounds.
VB2005 - I have a form that has three DGVs. Two of these DGVs have data that I want to plot on a chart (currently testing with MSChart). Im struggling to figure out how to just plot the data from one DGV. The DGV has a column Time and Level which I want o plot as X and Y respectively. Can this be done directly with data from a DGV?
