Formatting Axis Labels Based On Axis Label Values?
May 22, 2012I 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?

Aug 25, 2009I am having problems passing data from one form to another form opened from the first form.Here is my scenario: I have my start-up form. From this form I open a form by using the following:
[code]...
I use this because I want to be able to open multiple forms from the start-up form.Then from the PartyDetail form I open another form to display order details, like this:
[code]...
I want this order details form to be able to get a partyid variable from the party detail form.This works, but depending on the order that I open the forms the variables are incorrect Example:If I open the first PartyDetail form and then open the OrderDetail form, it works correctly. I can open as many PartyDetail and OrderDetail forms that I want and the variables are correct.But, say I open a PartyDetail form and then open another PartyDetail form and then open the OrderDetail form from the first opened PartyDetail form, it displays data based on the second opened PartyDetail form instead of the first. Basically, I want to be able to open multiple PartyDetail forms and then open OrderDetail forms based on whichever PartyDetail form it is opened from.Right now I am using Public Shared variables on the PartyDetail form and accessing this variable from the OrderDetail form. I suspect this is my main problem but don't know the best way to pass the variables from the PartyDetail form to the OrderDetail form.What would be the best way to do this?
VS 2008 Best Way To Draw This Simple Graph?
Apr 10, 2010Will any of the free light-weight charting libraries; ZedGraph or NPlot, be able to draw a simple graph similar to attached image (no waste of space, and with colored plot areas)? This plot will act much like the task manager "CPU Usage" plots, with update of last value every 500ms, but only making a new datapoint every 1 minute or so.
Or is this so extremely simple that it's better to hard-code it? What classes should I look into for this?

For i = 1 To 20

View 11 RepliesUse ZedGraph To Plot A Graph Based On Some Data?
Oct 2, 2009I'm currently trying to use ZedGraph to plot a graph based on some data I have extracted from a machine, with reference to a user entered "Frequency" range. I has to be a line graph, with Frequency on the X-axis, and extracted data on the Y-axis. There are 4 channels for the machine, but all data values extracted are close to each other, so multiple Y-axes are not needed. I'm also trying to do it within a class, and the graph should only be drawn when I click "Button3", otherwise there would be no data anyway and button2 extracts the data.
Below are my class (the graph code is at the bottom) and form1, which button3 should call the class, but I'm stuck for both the button interfacing and the class writing. I have also attached the output I get so you can have a look at what I need. Open it in Excel to see the format. The whole program is also attached as a text file if you prefer it that way.

Excel - Code In VBA And Recording A Macro - Input A Values For The X Axis Rotation And The Y Axis Rotation
Sep 16, 2009I 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.

RDLC Chart - Produce A Chart Showing The Month Along The Y-axis And The Value Up The X-axis
Jan 8, 2009I 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 would like to rotate them about an axis of rotation defined by a line through two 3d points.

My maths is a bit rusty now so is there a function that would calculate the axis easily ?

View 1 Replies.NET Chart Y-axis Scaling?
May 13, 2011I 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?
