Create a pretty line graph from two arrays in C#

Question

1.00/5 (1 vote)

See more:

I have two arrays. One of them contains DateTime and the other contains double. Is there a way to make a graph displayed from those data on an x and y axis?

Preferably the scale is automatic and the data is easy to visualize.

Thanks all!

What I have tried:

I have the two arrays, probably around a size of 100,000 each but I want to plot the values with the x axis being DateTime

Line graphs uses a series of x and y data points; you'll have to in effect "join" your 2 arrays to come up with a series of data points when it comes to loading the chart.

Write to a CSV file. Open in Excel. Create graph. Done.

Depends on the environment you want to run in.
For Winforms, I use the MS Chart control: Getting Started with Windows Forms Chart control | Syncfusion[^] may help.

My app is a console app. Some suggested outputting to a file and then using Excel, which may be easiest. I just thought there might be an easy one or two lines that would automatically create a chart from the code, where the user could stretch, zoom, and otherwise interact with the chart. Thanks!

No.
Console apps are text based, nothing else.
You want to display a chart ion a console app? Bad idea, and you are going to be looking at a reasonable amount of work that nobody really does any more - and certainly not in C#! That kind of thing died with C on early monitors that didn't support a graphics mode, and is just not a good idea for a modern app where doing it for windows is almost trivial in comparison!

i appreciate your reply. i didnt mean building it from scratch in console. i like console apps because they are computationally efficient. is it not possible to add a using statement to use winforms in a console app?

OriginalGriff 2-Oct-21 8:30am

Why would you bother?
They are fundamentally different: a console app is procedural, you the developer decide what is going to happen and when, and the user has little or no affect other then to type when he is told to.
Windows apps are different: the user is in control, and he decides what happens when by telling you when he is ready to do something by clicking buttons and so on - he can type in input boxes at any time.

Windows apps do that via message loops: they sit processing messages from a huge number of sources and running small bits of code as a result. Adding all that to a Console app is difficult and won't work when you start asking the user for input again!
Seriously: if you want a GUI, then use a GUI application!

So youre staying create a winforms app not a console app, is that correct? Are there built-in classes in Visual Studio for charts? The link you sent appears to be a third party thing?

OriginalGriff 2-Oct-21 10:02am

Yes.
There is a MS version of Chart - google will find it for you.

Cool, thanks.
