Return A Variable Based On The Input Of A Function (.NET C# Or VB)
Apr 12, 2012Say I've got the following variables:
Public Shared x As String = "100"
Public Shared y As String = "text"
Public Shared z As String = "something"
[Code]....
But this doesn't do what I want, naturally. What I want is that my function giveVar returns the value of the variable that holds giveVar. For example I call giveVar("x") I want my function to return "100".
Of course this can be done by a Select Case but thats not what I like to do. Is it even possible to call a value based on a string?

View 2 RepliesC# - Detecting Mouse Over Line In Zedgraph?
Dec 15, 2011I try to detect when the mouse is over a curve in zedgraph, I am capable of doing it if the mouse is over a point of the curve, but the problem is when the curve has no points in that region,let me show you an example:
Curve is defined by 2 points: [X=0;Y=10] -- [X=1000;Y=10]
If mouse is at point [X=500;Y=10] it is over the curve, but not over any point so i cannot detect it.Is there any event which gets fired when mouse is over line but not necessarily over a point?

View 1 RepliesVS 2008 Using ZedGraph To Draw Functions?
Mar 10, 2010I'm using ZedGraph to draw functions.I want it so, that the user can input a function.Eg:
txtFunction.text = x ^ 2 - 3
Graphs are drawn with this code
For x = 0 To 100
y = x ^ 2 - 3
list.Add(x, y)
Next x
This doesn't work
For x = 0 To 100
y = txtFunction.text
list.Add(x, y)
Next x
as the x can't be replaced.Is there an other way to draw graphs, by reading the function from a textbox?

Zedgraph - Y2 Axis Curves Won't Plot
Jul 25, 2010I have followed a tutorial from Zedgraph's wiki but I still seem to be having issues. When I run the code below, only the 3 curves on the Y Axis plot. I know the datasource is correct from which the 4 curves on the second Y axis are being created, because I have checked the table after creation. For some reason, however, the curves do not show up and the Y2 Axis does not change its scale to reflect any new curves. Does anyone see what I'm missing here?

Use 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.

Zedgraph, How To Convert XAxis.Scale.Min To A Date
Dec 16, 2011I use zedgraph to draw figures in my vb.net project. The x axis of figure is date. I have two text boxes showing the minimum and maximum values of x axis in date. The following code shows how to get x axis values when a figure is zoomed by using isEnableWheelZoom property, also see this link zedgraph EnableWheelZoom, how to get axis values after zooming?. But I found that I only get axis value, e.g. 4508.345, but NOT the date that I want. Actually on figure, it shows date correctly. My question is how to get the minimum and maximum date on figure?

View 2 RepliesIn Zedgraph, How To Dynamically Add/delete Bars When Axis.Type=Text
Jan 20, 2012I am using zedgraph to draw bar chart in my vb.net project. The bar base is Y (meaning all bars are horizontal). I have 9 fields for user to choose from, and once a user clicks a field, one corresponding bar will show. Of course, the user can click off the selected field to remove the corresponding bar item. I can do this. The basic idea is to get all bar items and set their visibility according to user's selection. My problems is that I want to have a textlabel next to each bar (this text label is different from legend)so I set the yAxis.Type=text. There are two problems:
1) When I add bars, I still need to specify x and y value. How do I set y value in this case to make sure bar ally perfect with its text?
2) As far as I know, I can add text labels by an array as the last line code shows. But obviously this only works for bar chart with fixed bars. In my case, the number of bars and also the order is changing based on user selection. How can I set text labels?

VS 2008 - Zedgraph Quality Inside PDF Depend On PageSize A4 Rotate
Jul 20, 2010For using you will need this two dll, I'm sure everybody knows that, but its probably the best.
[URLs] (this example use itextsharp-4.1.6 )
My Question
THe following Code will make a Graph, create a Bitmap, and start Adobe-Reade to present the Graph inside. The whole code works fine. I only have trouble, when I use this line:
Dim Doc As New iTextSharp.text.Document (iTextSharp.text.PageSize.A4.Rotate())
Instead of this line:
Dim Doc As New iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10, 10, 10, 10)
The quality of of the whole Picture is not good then. Eventhough when I change width and hight for the Rectangle. Then I tried to change the Bitmap width and hight, but in that case nothing happends? Any way, to handle the quality for using why nothing happens, when I change height or width in this line:
Dim Doc As New iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10, 10, 10, 10)
