I have a data point with a y-value of 1 being plotted, the MS Chart control will use increments of 0.2 on the y-axis. How can I force it to not use a decimal, keeping in mind I will have values of >100 so I can't just force an increment of 1 on the y-axis?
View 1 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 get this as a result:
I 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:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Chart1.ChartAreas("Area1").AxisX.Minimum = Val(XPrimeMin.Text)

Here's a silly question. I cannot believe I've spent so much time trying to figure it out. I have a textbox where I enter numbers, such as 12, 12.3, etc. I would like this data to display as 12.0000, 12.3000, etc. My line of code looks like this:

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:
<asp:Chart ID="chtNBAChampionships" runat="server">
<Series>
<asp:Series Name="Championships" YValueType="Int32" Palette="Berry"
[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 am using the MSChart object in VB2010. Live futures data is put into an array, then added one point at a time to a line chart (Chart1, one line only) using (1):
frmChart2.Chart1.Series("data").Points.AddXY(sec10, spreadarray(0, sec10))
All fine and good. However, by the time a few thousand data points have come through, its getting hard to see the detail in the chart, therefore I reset the x-axis so that I just see the last 200 (say) points, using (2):
Chart1.ChartAreas("ChartArea1").AxisX.Minimum = frmPrices.sec10 - CLng(lstChartpts.Text)
...where frmPrices.sec10 is the total number of data points, and CLng(lstChartpts.Text) is the number of points required. So if I have 1000 pts, and I wish to see 200 displayed, the AxisX minimum in this case is 1000 - 200 = 800. Points then start to build again one at a time. I am happy with this except that the Y-axis scaling is still taking into consideration all 1000 data values, so need to reset the Yaxis maximum and minimum. No problem (3):
Chart1.ChartAreas("ChartArea1").AxisY.Maximum = (max of the last 200 values + a small increment)
Chart1.ChartAreas("ChartArea1").AxisY.Minimum = (min of the last 200 values - a small increment)
The problem comes in when I want to change the number of points to display back to "ALL". I could re-write the code to use the max and min of all values, as in (3), but I'd rather just reset the yaxis back to the autoscaling that the chart started out with. I've looked everywhere for a property or method to do this! Or is there a way to autoscale the yaxis according to only the displayed values?
I have Date and Time available in xaxis() array format. I would like to assign this to x axis of the MS Chart. My all other data is in datatable format and already have assigned series to this values.Chart1.Series(0).Points.DataBindXY(xaxis, yaxis).. but it gives me error as i do not have valid values for y axis.
View 2 RepliesI 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.

Using 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 working on simple handover process from one mobile station to other. I got three proposed results service disruption time, network entry time, connection set up time. I also have the result of these three as by using some conventional way and got improved these three delay results by proposed way. Results are store in textboxes. Now i want to show graphically. E.g. I want to show conventional service disruption time on x axis and proposed service disruption time on y axis or vice versa. Let suppose I want to have a scale on axes from 1 to 3000 milliseconds. Then I want to show how purposed scheme is better. I am using VB.Net 2008.I have created chart. I also studied MS chart for windows forms samples environment. Also applied different chart properties like titles, series and others, But I am not able to make x and y axes scales. How to get values on the axes and how to generate graph? [code]
A chart element with the name '0' could not be found in the 'ChartAreaCollection'.i also tried using ChartAreas(Default") but i am getting same idea.I don't get what for this chartAreas value in parenthesis is used.
There are plenty of references on the Internet on MSChart (AxMSChart)for Visual Basic 2008, but the published code seems to have all sorts of problems. I am a novice and trying to get a line chart with scaled dates on the x-axis.
View 1 RepliesI'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]
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 RepliesI have X and Y data columns coming from database.
I have to show scatter plot chart with Linear, Exponential, Log, power using asp.net chart control.
Dim y as integer
dim x as double = 125 / 60

That method works, it removes all the numbers after the decimal.
But, how to check if the double contains a decimal and if it has it, remove all the numbers after it?

I have created a DLL that contains basic functions used in my projects. With the DLL I:Compiled it as a Release Moved the .dll file to another folder Deleted the .pdb files in the binRelease folder When I add the reference of this DLL to my projects and I debug my code, I step through line-by-line and when it comes to a function from my DLL, it actually opens up the source files of my DLL and debugs line-by-line in the DLL source code.
This is REALLY annoying for my purposes and I have tried many things now to disable the debugger stepping into my DLL code. I did a text search in the DLL file and found it stores the path of the project folder.
So far the only thing that's worked is moving/renaming the folder where the DLL project source files are. But everytime I re-build the DLL, once again I would have to move/rename the folder again as it's updated the location of the source.
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?

View 2 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.

View 1 RepliesI 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 can't figure out how to plot anything on this chart...finally got it to actually display a pie chart, now I'm trying to somehow bind a data source to it and from there, select the series data..I have added the database to the project as a data source but I don't know how to bind it to the pie chart. some other info: this db has 100's of tables and the program I'm working on is going to be a "status monitor" of sorts that will contain about 6-8 different types of charts all plotting different info for me in chart form.I want to bind this one data source to all the charts and just have them display different information (based on the sql query perhaps)

View 23 RepliesNormally I can get the webbrowser control in my vb.net application to scroll using the following code after the webpage loads into the webbrowser control: WebBrowserPageView.Document.Window.ScrollTo(50, 50)
But when the webpage uses the dom to update the page after the page loads, the scroll bars will scroll for half a moment to 50,50 but then snap back to 0,0.
I'm working with the webbrowser control because I've had so many problems with using a non wrapped browser.
What I'm doing is filling out web forms, pressing submit, filling more information, etc etc. The problem is that when I press the submit but inside the code, the webbrowser doesn't actually reload the page so the second step of form filling can never happen.
From what I've read I think this is because it's simply loading from cache. Is there someway to stop this from happening such that when the submit button is pushed, and the server sends the new page, the webbrowser reloads it automatically?
I have a webbrowser control built into a windows form of my application and I was curious if there was a way that any links that are clicked on in the webbrowser control will be forced to open in a new browser window?
