Now, with annotations, we can do some other things, like annotating last price for stock charts. ![]() The pyplot version returns both the Figure object and an array of Axes. pyplot.subplots: add a grid of Axes as in the example above. fig.addaxes ( 0, makes an Axes that fills the whole figure. For more advanced use cases you can use GridSpec for a more general subplot layout or Figure.addsubplot for adding subplots at arbitrary locations within the figure. There are a number of other methods for adding Axes to a Figure: Figure.addaxes: manually position an Axes. # ax1.text(date, closep,'Text Example', fontdict=font_dict) Example Draw 2 plots on top of each other: import matplotlib.pyplot as plt import numpy as np plot 1: x np.array ( 0, 1, 2, 3) y np.array ( 3, 8, 1, 10) plt. pyplot.subplots creates a figure and a grid of subplots with a single call, while providing reasonable control over how the individual plots are created. Xytext=(0.8, 0.9), textcoords='axes fraction',Īrrowprops = dict(facecolor='grey',color='grey')) ![]() If 'values' not in line and 'labels' not in line:ĭate, closep, highp, lowp, openp, volume = np.loadtxt(stock_data,Ĭonverters=)Īppend_me = date, openp, highp, lowp, closep, volumeĬandlestick_ohlc(ax1, ohlc, width=0.4, colorup='#77d879', colordown='#db3f3f')Īx1.t_major_formatter(mdates.DateFormatter('%Y-%m-%d'))Īx1.t_major_locator(mticker.MaxNLocator(10))Īx1.annotate('Bad News!',(date,highp), Source_code = (stock_price_url).read().decode() Here's a basic version of the command: In 2: fig, ax plt.subplots() ax.text(0.5, 0. Stock_price_url = ''+stock+'/chartdata type=quote range=1m/csv' The easiest way is to use the text command. The starting point code here is going to be tutorial #15, which is here: import matplotlib.pyplot as pltįrom matplotlib.finance import candlestick_ohlcĭef bytespdate2num(fmt, encoding='utf-8'): import matplotlib.pyplot as plt import numpy as np Fixing random state for reproducibility np.ed(19680801) plt.subplot(211) plt.imshow(np.random.random( (100, 100))) plt.subplot(212) plt.imshow(np.random.random( (100, 100))) plt.subplotsadjust(bottom0.1, right0.8, top0.9) cax plt.axes( 0.85, 0.1, 0.075, 0.8) plt.colorbar(caxc. Another is to specifically annotate a plot on the chart to draw attention to it. A common use case of text is to annotate some feature of the plot, and the annotate() method provides helper functionality to make annotations easy. One is to just place text to a location on the graph. The colors of the annotations have been partially changed for testing purposes. ![]() doing this in a loop like this: for ax in (ax1,ax2): do stuff works fine. Now I guess he also wants the annotation and the vertical and horizontal line in both plots. i copied OPs code, added your line at the beginning. In this tutorial, we're going to be talking about how we add text to Matplotlib graphs. 1 Answer Sorted by: 1 If you use the function to make the subplot a single array (axes.flatten ()) and modify it to draw the graph sequentially, you can draw the graph. at 12:27 r-beginners not directly related to the question.
