How can I set different colors in a ZedGraph histogram?

I got a histogram drawn in ZedGraph. And I have to set the specific color for a specific range of the values. For example: Graph Pane = zedGraph.GraphPane; list = new PointPairList (); for (int i = 0; i < 256; i++) { list.Add(i, array_with_y_values[i]); } Pane.AddBar("", list, Color.Red); And how I can set the other color for some of them? Are you looking for something like this? This piece of code adds 50 bars with random y values between 0 and 15. It will color bars with y values <5 as red, 5-10 as yellow, and >10 as green. GraphPane pane = zedGraphControl1.GraphPane; PointPairList list =

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I made a C# Winform application, my application briefly dealing with displaying sensors values during operating time, in addition to some other Input/Output tasks. Let's skip the algorithm part, (nothing special to mention here). For the display part, I decided to work with ZedGraph library for its awesome

C#: ZedGraph Show All Points of Zoomed Area

问题 I am plotting to my data to ZedGraph. Using FileStream to read files. Sometimes my data is greater than 200 megabyte. To draw this amount of data i should calculate peak values or must apply a window. However i want to see the all points of zoomed area. Please share any suggestion. PointPairList list1 = new PointPairList(); int read; int count = 0; while (file.Position < file.Length) { read = file.Read(mainBuffer, 0, mainBuffer.Length); for (int i = 0; i < read / window; i++) { list1.Add

Labelling and circle a specific point in zedgraph

问题 I am currently doing a project in which I've managed to identify the peak I want. However, I wanted to do more like circling the particular point with a label attached to it. Is it possible to do that in Zedgraph? I've attached a snippet of my code which only include a text label to that point, and I wanted to do more so people will identify the point more easily. PointPair pt = myCurve.Points[i-1]; const double offset = 0.8; TextObj text = new TextObj("P", pt.X, pt.Y + offset, CoordType

Draw date on X axis and time on Y axis using ZedGraph and C#

问题 In ZedGraph, how do I draw a time (like 00:00, 02:00, 04:00, etc.) on the Y axis and date (like 12-Apr-11, 13-Apr-11, 14-Apr-11, etc.) on the X axis? The bar settings has been set to BarType.Stack . Sample code will be very helpful. 回答1: Here is a sample that I constructed. I was not sure what sort of data you would plot along the Y Axis using a time format except for something like an accrued amount of time (such as number of hours employees worked). ZedGraph uses an XDate format for time

Why is my C# program faster in a profiler?

问题 I have a relatively large system (~25000 lines so far) for monitoring radio-related devices. It shows graphs and such using latest version of ZedGraph. The program is coded using C# on VS2010 with Win7. The problem is: when I run the program from within VS, it runs slow when I run the program from the built EXE, it runs slow when I run the program though Performance Wizard / CPU Profiler, it runs Blazing Fast. when I run the program from the built EXE, and then start VS and Attach a profiler

Generating and Saving ZedGraph plots without showing on forms

问题 Is it possible to plot data on to a ZedGraph graph and save it as a file without showing / generating a graph that is visible to the user? I'm looking to process a lot of datasets and generate a graph and saving it to a file for viewing outside of the application. If this can't be done, would it be possible show the graph on a hidden/minimized form, save the graph, close the window, and repeat for each graph? 回答1: It is possible. You create and manipulate the ZedGraph control as usual, but
