Python under Tinker, matplotlib mixed Programming Example One

The example is a candlestick (K-line) drawn with the Tinker embedded matplotlib, and the data is read from the CSV. It's a rough afternoon, and it's just for reference. The Python code is as follows:

Import Matplotlibimport matplotlib.dates asMdatesimport Pandas asPD frommatplotlib.figure Import figure frommatplotlib.finance Import CANDLESTICK_OHLC frommatplotlib.backends.backend_tkagg import Figurecanvastkagg, Navigationtoolbar2tkagg frommatplotlib.backend_bases Import Key_press_handler fromnumpy import Arange, sin, Pimatplotlib.use ('Tkagg') Import sysifsys.version_info[0] <3: Import Tkinter asTkElse: Import Tkinter asTkroot=tk.tk () root.wm_title ("CNY Exchange rate")
Root.iconbitmap (' My_logo.ico ') # Read Datadata= Pd.read_csv ("Data.csv", index_col=0, parse_dates=True) Data=Data.reset_index () data['Date2'] = data['Date'].apply (Lambda d:mdates.date2num (D.to_pydatetime ())) tuples= [Tuple (x) forXinchdata[['Date2','Open',' High',' Low','Close']].values]# Drawarea Setupdrawarea= Figure (Figsize= (Ten,5), dpi= -) Ax= Drawarea.add_axes ([0.1,0.2,0.85,0.7]) ax.spines[' Right'].set_color ('None') ax.spines['Top'].set_color ('None') ax.xaxis.set_ticks_position ('Bottom') ax.yaxis.set_ticks_position (' Left') ax.tick_params (axis='both', Direction=' out', Width=2, Length=8, Labelsize= A, Pad=8) ax.spines[' Left'].set_linewidth (2) ax.spines['Bottom'].set_linewidth (2) ax.set_xticklabels (data['Date2'], rotation= $, horizontalalignment=' Right') ax.xaxis_date () Ax.xaxis.set_major_formatter (mdates. Dateformatter ("%y-%m-%d")) Ax.set_ylabel ('Price ($)', size= -) CANDLESTICK_OHLC (ax, tuples, width=.5, colorup='R', colordown='g'); # a Tk.canvascanvas= Figurecanvastkagg (Drawarea, master=root) canvas.show () Canvas.get_tk_widget ().

Dateformatter ("%y-%m-%d")) Ax.set_ylabel ('Price ($)', size= -) CANDLESTICK_OHLC (ax, tuples, width=.5, colorup='R', colordown='g'); Canvas.show () Tk.label (Root,text=' Money'). Grid (row=0, column=0) Defaultvar=Tk.stringvar (Root) defaultvar.Set("CNY") #defaultvaluemoneylist= Tk.optionmenu (Root, Defaultvar,"CNY","USD","EUR") Moneylist.grid (Row=0, column=1) Btnrefresh= Tk.button (Master=root, text='Refresh', command=_refresh) Btnrefresh.grid (Row=0, column=3) Tk.mainloop ()

One example of data that can be debugged is named Data.csv, which is the same directory as the file above:

Date,open,high,low,close .- on-Geneva,30.49,30.64,30.34,30.57 .- Geneva-Geneva,30.50,31.64,20.34,25.57 .-Geneva-Geneva,30.49,30.64,30.34,30.57 .-Geneva-Geneva,30.49,30.64,30.34,30.57 .- to-Geneva,30.49,30.64,30.34,30.57 .- .-Geneva,30.49,30.64,30.34,30.57 .- --Geneva, -,30.64,30.34,30.57 .- ,-Geneva,20.49,30.64,30.34,30.57 .- the-Geneva,10.49,30.64,30.34,30.57
