I have x data as:

x_data:[[-210.99],[210.666],[553.211],[123.332],.....[234.121]]

If I have n columns then y1,y2,...yn should be plotted with x_data so that
within one graph n data can be visualized. I am also using slideshow for
visualizing a clear view of each column data. For appearing data as a
slideshow I am splitting each data of y1, y2,...yn into 5 data with x_data.

For example if I have columns as Col-1 and Col-2 then:

y1=[[10.556],[12.5687],[44.5568],...[66.6679]]
y2=[[10.4075],[12.5456],[23.5456],...[76.567]]

The split data of y1, y2 with x_data should be plotted multiple and appear
as slideshow. For that I combined into one array as

 splitArraylist=[array[[10.556],[12.5687],[44.5568],...[66.6679]]),array([[10.4075],[12.5456],[23.5456],...[76.567]])]

What I have tried is:

  checked_list=[1,2]
    gvalue=5
    self.XY(splitArraylist)
     def XY(self,y):
        y1=np.array(y)
        for i in range(len(checked_list)):
                self.splitXy(y1[i][0])
        self.graphXY()

    def splitXy(self,res):
        current_iter=0
        #Splitting each data of y1 into 5 graphs
        for j in range(gvalue):
                x_data.append(x[current_iter:current_iter+iters])
                y_data.append(res[current_iter:current_iter+iters])
                current_iter=current_iter+iters

    def graphXY(self):
        global cp, loopbool
        for j in range(len(checked_list)*gvalue):
                    if loopbool == True:
                            n_graphs.append(str(j + 1))
                            cp = int(n_graphs[len(n_graphs)- 1])

                            #PLotting each set of data in y1 and y2 with x_data

                            self.plotDraw(x_data[j],y_data[j])
                            loop = QEventLoop()
                            QTimer.singleShot(int(sec_value), loop.quit)
                            loop.exec_()
                    j = j + 1


    def plotDraw(self, x0, y0):

        self.MplWidget.canvas.axes.clear()
        self.MplWidget.canvas.axes.plot(x0, y0)
        self.MplWidget.canvas.axes.legend(('cosinus', 'sinus'),
loc='upper right')
        self.MplWidget.canvas.axes.set_title('Signal')
        self.MplWidget.canvas.draw()

Currently data is plotting one after the other data. That is first set of
data y1 and is split and plotted. Then next column y2 is plotted and appear
as a slideshow.

I actually want y1 and y2 data to occur in single graph and appear as a
slideshow. (i.e.) For the first graph of slideshow first split data of y1
and y2 occur in one graph then second split data of y1 and y2 ... likewise
5 graphs should be there.

How to do I do this? How can multiple plotting be achieved using loops and
arrays?
