Aviod joining two strokes of drawing while making a plot using kivy garden!

[Shruti Chandra]

Hi, I am plotting a graph reading a file with x, y positions. These drawings are in form of letters(y, c etc).
In actual drawing there is a gap (visually) in the strokes of letters, but when i am making a graph using kivy garden. It is somehow joining the two strokes with a line.

In the attached pic, you can see there are two strokes of y, one is small (first one) and second is remaining full y. Both two strokes are attached by a straight line (approx pos: 600, -80).

How can I avoid this?

Thanks in advance! Quiet new in kivy!

You should put each connected series in its own Plot (so, for this example, you should have two Plots).

I am putting the block of the code which I am calling in App. Every time it is reading the strokes and plotting the graph, so for every stroke there should be new graph. Could you please tell me where i should change the code?



def draw(self, curr_data):
       
        point_list = []
        point_list_x = []
        point_list_y = [] 
        for stroke in curr_data:  
                 
            for i in range(len(stroke)):
                stroke[i][1] = - stroke[i][1]
                #xp = storke[i][1]
                a = tuple(stroke[i])
                point_list.append(a)               
              
           
               
            graph = Graph(xlabel='X', ylabel='Y', x_ticks_major = 50, y_ticks_major = 20, y_grid_label = True, x_grid_label = True, padding = 5,
            x_grid = False, y_grid=True, xmin = 500, xmax = 800, ymin=-180, ymax=-50, draw_border =  True)
            plot = MeshLinePlot(color=[1, 0, 0, 1])
            plot.points = (point_list)
            #plot.points = (stroke[:, 0], -stroke[:, 1])
            #print '----------------', plot.points
            print point_list_x
            print point_list_y
           
            graph.add_plot(plot)
            graph._plot_area
            graph.pos = 30,120
            graph.size = 400,400
            self.add_widget(graph)

Hi, Problem solved.

Here is my updated code.

        num = 0
      
        point_list = [] 
      
        for stroke in curr_data:
           
            print '+++++++++++++++++++++++++++',stroke
           
            num += 1

           
          
            graph = Graph(xlabel='X', ylabel='Y', x_ticks_major = 50, y_ticks_major = 20, y_grid_label = True, x_grid_label = True, padding = 5,

            x_grid = False, y_grid=True, xmin = 500, xmax = 800, ymin=180, ymax=50, draw_border =  True)

           
           
            plot = MeshLinePlot(color=[1, 0, 0, 1])           

            plot.points = stroke

       
            graph.pos = 30,120
            graph.size = 400,400
            self.add_widget(graph)

            graph.add_plot(plot)     #   
            print num
