Visual studio array plotter

Imagine for a moment that you are stranded on a deserted island only create csv using camel your laptop, your task is to write a compiled application that will let the user load a file with numbers and plot these on a graphic. For the sake of argument let's suppose you have a Windows based computer and, because Windows does not include any compiler by default, we'll also suppose you have Visual Studio installed.

What would you do? Last week I was in a similar situation when my internet connection was down for two days and I was pressed by a client to add some 2D graphical capability to a C application, the deadline for this project was quickly arriving and no third party library was allowed, only what is included by default with VS My solution was to use the Chart control for plotting the data on a Windows Form.

The by-product of this project was this post in which I will show you how to add to a C application a plotting area that will allow you to plot and save the graphics as high quality images. This tutorial is intended to be self sustained even for a beginner so I will exemplify each step of building this app with screenshots.

If you are an advanced C coder feel free to skip the boilerplate sections. Next figure is an example of what kind of graphics you can create with the app we are going to build:. In case you are wondering, this is the formula I've used for generating the data for the upper picture:. Press OK. You should end up with a fresh Windows Form in your Design panel:. From Solution Explorer right click Form1. Press Yes when VS will ask if you want to rename this in all references.

Right click on the Form and select Properties, this will open a new Properties panel at right, change the value for Text from "Form1" to GraphDemo. You should see the new name on the Form.

Change the Size property of the Form fromtoof course you can achieve a similar result by dragging the lower right corner of the Form. As you can guess by now, our application will allow the user to open a data file, plot the data and save the resulting image. Let's add some code to the above submenus, double click on Exit, this will create for you an empty function that will be called when the user presses Exit:.

If you haven't made any error you should see the app running. Try to close the app using the Exit submenu! Next, we will implement the Open functionality. In order to keep the code simple we will assume that the user will only load csv files comma separated valuese. If you will copy the above code in GraphDemo.

The above function will only let us use the Open submenu to select a csv file from our computer, we still need to add the code that will actually read the file. For actually reading a bmw 325ci file from the disk we will create a new C class. We will add code for parsing a csv file and for storing and retrieving the header and the data. Let's start by creating a few private variables used for storing the data and the functions used for getting this data:.

Like before StreamReder will be underlined in red, right click and chose Resolve We are ready to use the Read class, open GraphDemo. In the above code we have used an undefined variable rr, which is a Read object. Scroll at the beginning of GraphDemo. This is a possible arrangement for the GUI feel free to move the elements as you see fit :. Apply the same procedure for label2, change the Text to Y-Axis.

Do not change the Text property for the ComboBoxes! For btnPlot change the Text property from "button1" to "Plot". If it works than it is OK :D, you can close the application, we have work to do.

We'll start by populating the two ComboBoxes using the header of the input csv file.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again.

The PyData ecosystem has a number of core Python data containers that allow users to work with a wide array of datatypes, including:. Several of these libraries have the concept of a high-level plotting API that lets a user generate common plot types very easily.

The native plotting APIs are generally built on Matplotlibwhich provides a solid foundation, but means that users miss out the benefits of modern, interactive plotting libraries for the web like Bokeh and HoloViews. To start using hvplot have a look at the Getting Started Guide and check out the current functionality in the User Guide.

Mostly I use textual representation of the objects by editing autoexp. But for some of the variables it is better to have a plot rather than having values in textual form.

In general I am interested to have something like Matlab or Ch IDEwhere I can plot certain variable externally when the program is at a debug break.

Since VSVisual Studio has included Visualizerswhich could almost have been designed specifically for your problem. MSDN explains the concept better than I can:. Visualizers are a new component of the Visual Studio debugger user interface.

A visualizer creates a dialog box or other interface to displays a variable or object in a meaningful way that is appropriate to its data type. For example, an HTML visualizer interprets an HTML string and displays the result as it would appear in a browser window, a bitmap visualizer interprets a bitmap structure and displays the graphic it represents, and so on. Some visualizers allow you to edit as well as view the data. See here for a tutorial on how to write one.

As others have noted, I'm not sure exactly what do you wish to plot. I usually understand, when someone says he wants to "plot something", he usually means some array with numerical values. If this is true in your case, Intel's Array Visualizer is maybe of some help. It can be downloaded freely, it integrates into visual studio, and you can use it in two ways: as a standalone application or while debugging "while in some breakpoint" so you can plot array values "while program is running".

Could you use gnuplot for this? Spit out the data you want to plot as debug prints, and then while you're sitting at a breakpoint, copy it to an external file and run it through the plotter.

But this method has two disadvantages: First is that, function overloading almost never works when calling a function from debugger so I had to pass type as a second parameterand the function call occasionally crashes, though it works perfectly when called from within code.

Yes, if you use notebook interface. And last month they MS improved their python extension to support Jupyter notebooks right in the Visual Code together with.

Get extension here and check blog post how to use it with Jupyter notebooks. Another one is Neuron, under development, but looks nice - again, notebooks in VS Code, with graphs, markdown etc.

Get it here. One way to use plots in Visual Studio Code is with Juypiter notebooks. You need to install the official Microsoft Python plugin ms-python. Docs: Create or open a Jupyter Notebook. The Plot Viewer gives you the ability to work more deeply with your plots. In the viewer you can pan, zoom, and navigate plots in the current session.

Within the Notebook Editor window, double-click any plot to open it in the viewer, or select the plot viewer button on the upper left corner of the plot visible on hover.

One great feature would be a checkbox so NaN values are ignored in the plot. Love this tool. Is there a workaround to install it into the new VS? I will be working on a VS release shortly, but that requires I install first! FYI ArrayPlotter 0. I would love to love this tool and am super impressed with what you've done! I've tried your demo solution and it works fine Visual Studio However, when debugging C code while attached to a Unity instance, I cannot seem to get the plotter to recognize my array in the Y: expression.

I know it can see bufferCheck because I can put bufferCheck. Any thoughts? Hi o2deprived, Sadly the problem isn't with you! My understanding is that Visual GDB and seemingly Unity Editor publish things like variables, callstack etc to Visual Studio via a debugging API, that means Visual Studio doesn't actually have access to the raw memory of the ultimately debugged application.

ArrayPlotter requires access to the raw memory to copy over in chunks. So in this case I assume that the Y Pointer expression fails due to being unable to return a memory address. Alternatively I could build the array up element by element But that would be rather slow.

I may look into this in the future, in the cases where direct memory copy fails. But for now, sorry, but it doesn't look like ArrayPlotter supports debugging of Unity applications. Thanks for the explanation Rodney -- really appreciate the quick response! And there is absolutely no need to apologize. I'm debugging some audio analysis code and being able to visualize the mountains of data is paramount to understanding where things are going wrong. For now, I'm getting by, selecting the data in a watch view and simply copying it to Excel and graphing it there.

It's a bit cumbersome, but it does work. I saw your plug-in and thought it would be the holy grail for what I was needing -- but such is the way of things. Thanks again for your efforts on this project and if you ever decide to see about making this work, I for one will be all over it!

Awesome tool! Is there any way to make it work with Intel compilers? I would love to use this with Fortran applications. Hey there, that is an interesting idea. I have a theory for how I might be able to make it work with external toolsets ie Visual GDB is the previous example that has been askedbut it would be slow see comment above. So at the moment, I don't know how to make it work, but I may be able to do so in the future.

How would one go about plotting 5 series of 10 points each based on C array 'double a[5,10]'? I could swear i was able to do this in the past Thanks Rodney. Unfortunately those do not work with a 2D array.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I am trying to create two plots, and show them in separate windows at the same time. A simple example is. But the second plot does not show up unless I close the first plot. Similarly for a larger script, the rest of the code chunk after plt. I tried executing without debugging and it does not work. However, when I run the same code in Ipython interactive window, all the code executes and I can see both plots as inline, yet it is not what I want.

I want to all the code to run creating as many plots as needed in different windows without me interrupting like closing the plot for the rest of the code to run. I can still do it in Spyder, but I want to switch to Visual Studio completely and this issue is bugging me.

Now I don't know how this would work in VS but whenever I have to make multiple plots in interactive window without saving them and I want to display all of them together this is what I do:. To have an interactive window that doesn't obstruct the rest of your code, you have to use IPython, or some other tool which enables async plotting and calculations. However directly from Python interpreter, you're going to have to wait until you terminate that line.

Additionally you could turn on interactive mode by doing plt.

This enables direct view to your plot, which updates after you issue commands pertaining to it. I believe that is the actual command you're looking for. Here's the manual. I haven't done this in Visual Studio but with Matplotlib you can use a non-blocking call to show.

The draw method does not block but if you don't end the calls by doing a show then the graph window will immediately close. Here is a related question on the same topic. Personally I use subplots as shown in the matplotlib examples. Then you won't need plt.
