Starting the vector with a certain value and the value starts at zero visually on the graph

I am writing an unscented kalman filter code to estimate many parameters. It does not start the graph with the value corresponding to the initial vector. I start the vector x (:, 1) = [118562500 25 * 10e6 3 * 10e6 44000000 22000000] ', but when plotting the graphs, apparently all are plotted correctly and only the last position (22000000) starts at zero, which in theory in the chart should be at 22000000. But when looking at the table of interactions the value starts at 22000000. I am putting the code and graphics. I looked in some places and found nothing to help. I'm grateful for any information that might resolve this error.

It also follows the table with the interactions carried out by the code that I am trying to plot
