ZedGraph | Fork of John Champion 's ZedGraph charting framework

I have three Forms in my project. Form2 Connects the Serial Port. Form1 writes and reads data from the Serial Port. Form 3 only needs to write to the serial port, however when i send data to the serial port I get an "Port is closed error". I do not see any difference in the way i set up form 2 and form 3 so i am not sure why Visual Studios is giving me the "port closed" error.

Form 2 will connect to serial port

When GraphPane contains only one CurveItem rime series, everything works fine, each new point is added to the chart and displayed without gaps or missing values.

Then, I add second time series to the same GraphPane and data points in these time series come in with different frequencies, so they have different values on X axis, data type of X axis is set to DateAsOrdinal. At this moment, when I add data points to each time series, chart seems to try to synchronize data points in both time series and populate difference between data point in the first time series and data point in the second with some average intermediate values.

Example

Windows Forms ZedGraph control in WPF application. The data points are auto-generated and attached to the chart every N seconds. When new data point is added to the chart I shift (pan) chart one point to the left, so there is always no more than last 50 points visible in the viewport. Overall, it works pretty good, except for two things.

Issues

1. If user tries to zoom in or out, the viewport stops following the last data point and chart goes outside of the screen, so panning stops working
2. I would like to pan or shift chart using mouse event, without scrolling, but when I press right mouse button and try to move it to the left, it tries to zoom chart instead of panning

I wrote the following code in C#:

My task is to implement a random number generator using LCG algorithm.

The task is to generate 1000 axes (x,y) between [-1, 1] and print them on a pane.
If the point is inside the circle of radius 1.0, it will be printed as Red.
Otherwise, Blue.

I used the parameters suggested by Numerical Recipes suggested in this YouTube video. I am following the coding style used in this link.

I am using ZedGraph to show my plots.

Why are the random numbers not properly scattered on the pane?
And, where are the blue points?

Random number generator class:

i am converting a windows form application to asp.net, the main issue i have is that i cannot add the connectionstring or appsettings TAG, it continues to give me the error that my web.config file is not valid: "is allowed only one configSections and must be the first child of configuration

If you run with this web.config it works, but if you uncomment the connectionstring it gives error

Here my file web.config:

I have a Dictionary with Key and Value Pairs. I need to create a Line Graph on zedGraph, plotting the Key in the X-Axis and the Value in the Y-Axis. I am using Visual Studio 2017.

the Key is a DateTime type. The Value is a string type.

I was thinking of creating 2 arrays, an X-Axis Array and a Y-Axis array.

Any other/quicker/more optimal suggestions?

I have already tried converting the DateTime values into Ticks, but i cannot create a loop to print them. It gives me an Error:

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 culled based on the xScale and yScale of the GraphPane.

This way you can have millions of points loaded, but when the zoomlevel of the graph would show all the points, they can be culled so that ZedGraph is only drawing a few thousand. As the zoom magnification is increased, fewer points would be culled in the region of interest.

I wanted to know if ZedGraph already offers anything like this out of the box. I haven't seen any indication of support for it.

Does anyone know?

I am new in C# and trying to create zedgraph of lessor sensor. First I create a global variable and write code for graph. My graph is working but after reached to the point of 100 of x axis it will overlap to old line. z1.GraphPane.CurveList.Clear(); command is not working. I tried listPointsOne.clear(); command also but that clear the line and doesn't show anything on graph. Please help me out with this. My code is below :
