Function for subplots for real time plotting in Python

I have a code which gives me 4 individual live plotting graphs for 4 different sensors. But, I want them in a single frame using subplots. Pasting the piece of code which are plotting my graphs. How should I modify them for my output to be a subplots of 4 live graphs.

def makeFigure(xLimit, yLimit, title):
    xmin, xmax = xLimit
    ymin, ymax = yLimit
    fig = plt.figure()
    ax = plt.axes(xlim=(xmin, xmax), ylim=(int(ymin - (ymax - ymin) / 10), int(ymax + (ymax - ymin) / 10)))
    ax.set_title(title)
    ax.set_xlabel("Time")
    ax.set_ylabel("Detector Output")
    ax.grid(True)
    return fig, ax

pltInterval = 50  # Period at which the plot animation updates [ms]
    lineLabelText = ['Detector A', 'Detector B', 'Detector C', 'Detector D']
    title = ['Detector A', 'Detector B', 'Detector C', 'Detector D']
    xLimit = [(0, maxPlotLength), (0, maxPlotLength), (0, maxPlotLength), (0, maxPlotLength)]
    yLimit = [(-1, 1), (-1, 1), (-1, 1), (-1, 1)]
    style = ['r-', 'g-', 'b-', 'y-']  # linestyles for the different plots
    anim = []
    for i in range(numPlots):
        fig, ax = makeFigure(xLimit[i], yLimit[i], title[i])
        lines = ax.plot([], [], style[i], label=lineLabelText[i])[0]
        timeText = ax.text(0.50, 0.95, '', transform=ax.transAxes)
        lineValueText = ax.text(0.50, 0.90, '', transform=ax.transAxes)

        anim.append(
            animation.FuncAnimation(fig, s.getSerialData, fargs=(lines, lineValueText, lineLabelText[i], timeText, i),
                                    interval=pltInterval))  # fargs has to be a tuple

        plt.legend(loc="upper left")
        plt.subplot(2,2,i)
    plt.show()

    s.close()

What I have tried:

I have tried editing this function with regular subplot commands but am getting many errors.
