Hello John, Thank you very much for your message. All good, things can easily be overlooked. That's why I asked cautiously. There will be a maximum of 2 graph lines. The blue one shows a current, the red one shows the corresponding voltage. The reference curve is the blue one (current). This current can only be positive, sometimes only negative, or both. It doesn't necessarily have a value that goes through 0. In the example it is between 100 and 2850 amperes. The same applies to the voltage. This...

Derek, Sorry this had dropped off my radar because I had not seen the source code in your last message. I know it is frustrating when trying to get an answer online and no one is responding! I have it downloaded and compiling on my computer now and will take a look at it. A few questions to help guide behavior: Does this need to work with more than 2 graph lines at a time? Can we set a 0 point for the graph, IE can we define a percentage of the graph height where 0 should lie? For example if we set...

Hi John, it took a little while to scale down the actual project so that only the problem itself remained. As you can see from the attached picture, the two zero points of the Y/Y2 axis are not at the same height. Therefore, I would like to move the two graphs within the graph pane so that Y0 of the two Y-axes are congruent. Zedgraph probably does not provide such a function as standard. But in this thread (and this is the only one on the www that I could find) it is discussed. Unfortunately the...

Understood, but having abundance of information makes debugging easier. I can work with a vs vb project, so if you can send that ready to show the problem it is having, with an image of the graph you want to produce, I can try to get that working tonight. Even dropping the text from your image in so i dont have to retype it would help. Thanks, John Vickers

Hello John, thanks for the offer. My problem is not that I generally don't get along with zedgaph, but that some properties are simply not members of zedgraph classes when I translate the above C# code to VB. he same problem probably exists in C#, but I can't test it quickly because I'm only running VS with VB. So I'm wondering, where do these properties come from? Are these legacy? However, I can't find any meaningful information about it.
-
I can give you a hand debugging your code, but it is mich easier to start from a sample project that demonstrates your problem. Can you either post or DM me a zip of a sample graph with data as you are seeing it, and describe what you are trying to change on it? I will be able to look at it later this evening if you do. Thanks John Vickers

Hi hello, I know this is a pretty old thread but maybe people will still read it. I have the exact problem that I'm still using Zedgraph in an older application and I want to make the axes Y and Y2 coincide with the zero point in the graph. I use the latest zedgraph version 5.1.7. and program in VB. Therefore I translated the above code. But unfortunately [.IsMinorOppositeTic] and [.Step] are complained about as not being members of ...Axis. What's more, I can't find any real information on the web...

Not sure if this is better here or as a "help requset, so i apologize for the double post Im using zedgraph in a csharp page to generate a graph. I'd like to try to make it load a custom font (a .ttf file) to use as the font. This is running in an environment in which I do not have access to the standard windows fonts directory.

The code you sent isn't the problem.

Hi Vladimir, The error is quite clean actually. RenderGraph is an event.. But you're calling it directly.. You need to share the delegate code in your 'VB translation' before anyone can help.

If this project isn't too urgent I can help you fix your issues (probably the week of Christmas) because I am swamped with work right now. If it is more urgent, and you had a version working with 4 separate graphs, my suggestion would be this: 1) Create a function that can set the scroll position of all 4 graphs 2) Subscribe to the scroll event of each graph 3) In each event, read the scroll position, then feed that into the function to set all the graphs to the same scroll position. Doing the master...

Zedgraph doesn't have organized development/support right now and hasn't for some time. It is still has good feature content, particularly when you consider that the baseline is ~11 years old. I don't know that the SourceForge documentation links ever worked as that was the project that was being fleshed out at the time support was dropped. There was a web library independent of SourceForge that had the examples for awhile. You may be able to find that in a web archive. I have a couple times over...

Andy, Take a look at my sample project that demonstrates how to display live data on a scrolling graph with timestamps correctly that don't jump. I suspect it is exactly what you are trying to do. https://github.com/jgvicke/ZedGraph_SineWave By the way Tom's posts were from 2013. On posts that old you are better off starting a new thread instead of tacking onto an old one. John

ZedGraph data points are received through the IPointList interface. If you look at this interface, you will see that you can create any kind of data structure you want in your own custom class. All your interface needs to define is an indexer into your data structure. So create your own class that implements IPointList. Then write your code that updates the data inside your class using the logic you described with start and stop functionality. Call AddCurve on the GraphPane and pass in your IPointList...
-
Peak Counting is typically a local maxima problem. The simplest algorithm divides the time into discrete intervals. For each interval, find the maximum. You will then have one peak for every interval. Then you can plot your peaks. There are other algorithms that get more sophisticated, but how you do it depends on exactly what you consider a peak. For instance, you may want to only count a maxima as a peak if it has a sharp angle that exceeds a certain threshold. In that case, you could apply that...
-
I've searched and can't find an answer to this question. I could write the code myself to do it, but I don't want to reinvent the wheel. :) Since ZedGraph uses an IPointList and its indexer for internal data access, you can assign any kind of data structure to it and dynamically change the data that ZedGraph receives when it calls the indexer. It's a smart architecture, and naturally, it would be feasible to implement a Level-of-Detail system using a custom IPointList where the number of points is...

John, Thanks for reply. I was able to achieve this by adding these lines to my previous code plotpeakcurve.Line.IsVisible = false; Fill fill = new Fill(Color.Red); plotpeakcurve.Symbol.Fill = fill; plotpeakcurve.Symbol.Size = 15; now peaks are plotted exactly. Regards, Mukesh.

Mukesh, I updated my scrolling example with setting a peak dot. Redownload the current version from GitHub and run it to see if it does what you are looking for. If it does take a look at the last 2 commits to see the extra parts I added to make it work. https://github.com/jgvicke/ZedGraph_SineWave/commits/master I think you are trying to make it harder than it needs to be. By the way, Zedgraph will put the first curve added to the pane on top of all the others, so in my code if you reverse the order...

Mukesh, You wouldn't want a function to test the entire series and return points, you would want to add points as they come in live. You have one series for the main graph that is a line without points. Make a second series that is a point without lines, of a different color. This will be your "peak" markers. Plot them both on the same graph with the peak line on top (there is a z parameter for the lines you can use to order them, or you can just add the peak line after the data line). Now, as points...

A peak is defined as a point which is higher that both neighbors or infinity. Non-infinite end points are excluded as a peak. I am looking for function which is similar to MATLAB find peaks() Using Zedgraph lineseries. Any suggetion would be very helpful. Thanks in advance, Mukesh.

Hi John, Thanks for your time and effort. Iam going to call a peak as- How many threshold values in my plot, threshold is given by user in a text box. eg: If iam giving a threshold as 40 all the points above 40 should be marked (Y data will be value from a sensor ranging from 0- 200) (X data time) I am not using any Z varialbe in plot. please find the screenshot attached for reference. I tried using some algorithm available in general in c#(by keeping all the X and Y variables in separate arrays)...
-
Mukesh, There are lots of ways to find peaks, the hardest part is figuring out how you want to determine peaks. Simple is if the last point was higher than the points to either side, it was a local peak. You may make rules that a peak has to be x higher than the troughs around it. You could say anything over Y value is a peak. You first have to be able to describe what you are going to call a peak, then you can look at programming it. Easiest way to mark them is have a second point pair list that...

First thing to check is that the date is importing correctly. Does your c3 variable have the correct C# DateTime object that you expect when you put a breakpoint there? If you are getting correct datetime into the c# object, next I would check how you finish the graph. If you are not doing a live graph (just loading a data set), I would not set your bounds at the top with the scale min and max. After you have all the data added to your graph, call the axischange function, then call zedGraphControl1.Invalidate();....

Mukesh, Go check out my scrolling graph example here: https://github.com/jgvicke/ZedGraph_SineWave It deals with graphing real time data with timestamps. You will need to convert your time string to a real time in C#, something like: DateTime dateTime = DateTime.ParseExact(time, "yyyy-MM-dd h:mm:ss tt", CultureInfo.InvariantCulture); Then use the xdate functions in zedgraph to convert a C# date into the date format for the zedgraph point.

-
I will add that it sounds like you are trying to get too much data on a single chart. In general, most people cannot digest very complex live charts, you are a lot better off keeping each chart simple, but having multiple charts to look at. In most commercial software, it is rare to even see 2 real time variables being plotted on the same strip chart. Can you link an image of what you are trying to achieve? Even a hand drawn sample of what you are thinking would be useful. John

I haven't used ZedGraph in a long time. What version do you have? I downloaded the control, and then tried to use your code. It does not compile as written because pane is not defined. Also, where and how are you calling GetImage()? Can you post up some working code? Example: private ZedGraph.ZedGraphControl z1; public ZedGraphForm() { z1 = new ZedGraphControl(); z1.Location = new System.Drawing.Point(0, 0); z1.Name = "zedGraphControl1"; z1.TabIndex = 0; InitializeComponent(); zpath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);...

I've got a ZedGraph with several LineItems and a single BarItem and this renders as expected on the screen (bar item appears as a solid two-colour bar across the full width of the graph, red/green for moving/stationary). The colour of each individual bar point is determined by the Z value (1/0). The settings used were: pane.BarSettings.MinClusterGap = 0.0F; pane.BarSettings.MinBarGap = 0.0F; Color[] colours = new Color[] { Color.Red, Color.Green }; bar.Bar.Fill = new Fill(colours); bar.Bar.Fill.SecondaryValueGradientColor...

The only thing I can think of is you accidently modified my code. The only line with that function, there are 4 arguments. If VS is seeing 3 arguments, maybe you accidently deleted a comma. John

... not the same error.... for "_myPane.FindNearestObject(new PointF(e.X, e.Y), this.CreateGraphics(), out object nearestobject, out int index);" I get now the error: "No overload for method "findNearestObject" takes 3 arguments" Any suggestion?

I try to install with NuGet Zedgraph library 5.1.5 and Zedgraph 5.1.7, but with booth I get the same errors.

Hi John, I did as you mentioned, but still the same error!

I just downloaded my source code from GitHub to see what you would be seeing and evidently it didn't carry the ZedGraph DLL with it. Do this: 1) Open the solution 2) Right click on the solution in the solution explorer 3) Click "Manage NuGet Packages for Solution" 4) Click "Browse" 5) Search for ZedGraph 6) Install it into the solution 7) Clean and Build the project Let me know if you still have errors because this worked just fine for me. Thanks, John Vickers

Hi John, I have checked your source code example! But I got the "nearestobject" error. Google was not my friend in this case, I have no idea, what is wrong.... Maybe you can help? Michael

Michael, You should check my source code example, it will work for you. https://github.com/jgvicke/ZedGraph_DirectPointEdit John Vickers

Hello Libor, I try out your sample code and try to compile it with Visual Studio 2010. But I got errors.... the expession "nearestobject" is invalid. What is wrong? Greetings, Michael

Hi All, I have implemented ZedGraph in windows application (c#) and its working great. But facing one problem in auto scroll section. In first one minutes section candle stick graph generate one by one in the panel on each second. Once the time reached to 60 second, application starts scrolling. In next each tick, application generating new candle and graph moving forward to x axis. As the time increased slowly and gradually new graph generation position shifted towards left side (as shown in the...

The best sample I could give you is the ZGControlTest.sln from the zedgraph_sample_projects_5.1.2.zip. You might be familiar with that:-) When hovering over the points it is the font (in particular the size) used to show the point values that I want to change. I think I have tried all the fonts I could find under zedgraph, pane, chart, curve, label, etc. in order to change the font without any luck. Eric

If you can post a sample project with how you have it now, I will see if I can find the setting you are missing. John Vickers
