Hey, I'm working on MPU 9250. I want to plot real time data of MPU in 3D, I'm able to plot real data in 3D, the plot contained all the data from first reading to the last but I want to plot the first reading then the second reading and so on. I'm not able to plot the data. Please help me.
Thank you in advance.
Regards,
Aradhya Tare

Aradhya - how are you plotting the data from the first reading? How do you then plot data from the second reading? Please include a sample of your code. And is the "first reading" a single point or is it multiple points?

Aradhya - everytime you call plot3 you are creating a new plot (graphics) object and the previous one is deleted. Perhaps that is why you are not seeing all of the data being plotted (if I understand your question correctly). Rather than using a loop to plot the data, just do it all at once
plot3( x_accel(1:999), y_accel(1:999), z_accel(1:999))
Else if you want to plot each point (with perhaps a pause between each one), then you will want to create one plot object and update that on each iteration of your loop
hPlot = plot3(x_accel(1), y_accel(1), z_accel(1));
for k = 2:1000-1
pause(0.5);
xdata = [get(hPlot, 'XData') ; x_accel(k)];
ydata = [get(hPlot, 'YData') ; y_accel(k)];
zdata = [get(hPlot, 'ZData') ; z_accel(k)];
set(hPlot, 'XData', xdata, 'YData', ydata, 'ZData', zdata);
end
I haven't tested the above, but it should work something like that.

Sorry, Aradhya. Try removing the semi-colons:
hPlot = plot3(x_accel(1), y_accel(1), z_accel(1));
for k = 2:1000-1
pause(0.5);
xdata = [get(hPlot, 'XData') x_accel(k)];
ydata = [get(hPlot, 'YData') y_accel(k)];
zdata = [get(hPlot, 'ZData') z_accel(k)];
set(hPlot, 'XData', xdata, 'YData', ydata, 'ZData', zdata);
end
