How to draw circle by data with matplotlib + python? -


I can draw a circle with scatter , which is shown in the image. But I want to draw them to buy a line, since there are several divisions in total, I need to add the nodes together for a specific cycle. Thank you. Enter image details here

Make some random sequence points first:

NP angle = NP. Range (0, NPPI.2, 0.05) r = 50 + N.P. Randem. Normal (0, 2, angle.Sp) x = R * np.cos (angle) y = r * np.sin (angle) idx = np.random.permutation (angle.shape [0]) x = x [idx ] Y = y [idx]

Then use arctan2 () to analyze the angle, and sort the data by: 

  angle = np.arctan2 (x, y) command = np.argsort (angle) x = x [command] y = y [command] fig, ax = pl.subplots () ax.set_aspect (1.0 ) X2 = np.r_ [x, x [0]] y2 = Ax.plot (x, y, "o") ax.plot (x2, y2, "r", lw = 2)

NPR_ [y, y [0] is produced here:

Member with no value in F# -

After I am trying to convert F # to the following C # code: [StructLayout (LayoutKind.Sequential, charset = CharSet.Ansi)] Private class DOCINFOA {[MarshalAs (UnmanagedType.LPStr)] public string nomeDocumento; [Marshall (UnmanagedType.LPStr)] Public string arquivoSaida; [Marshall (UnmanagedType.LPStr)] Public String Tipodo; } I am doing the following: Named place printer module RawPrinterHelper = [& LT; StructLayout (LayoutKind.Sequential, charset = CharSet.Ansi) & gt;] Type DOCINFOA = [& LT; MarshalAs (UnmanagedType.LPStr) & gt;] Member this.nomeDocumento [& LT; MarshalAs (UnmanagedType.LPStr) & gt;] Member this.arquivoSaida [& LT; MarshalAs (UnmanagedType.LPStr) & gt;] Member This Tipoda [/ code> But I get: One type of definition is necessary for one or more members .

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
