Hello,
I am running a test in which the value of RPM first goes up linearly and them comes down linearly and i want to plot the values obtained as output for each RPM. But since i want to plot this in xy graph as the RPM starts decreasing the graph starts moving backwards, to overcome this i kept on plotting the data where the RPM values appear to go beyond the limit but they are actually decreasing, so that the test is running backwards. Is there a way so that the x-y graph x axis shows the real values of RPM. I am attaching a figure where the test first runs forward and then backwards and both are plotted on the same graph.
Thanks

Hi Kirtikant,
No, you cannot have 2 different X-values correspond to the same point on the axis. The graph you are plotting now is a kind of Hysteresis graph, which is nice for some applications.
Your other choice would be to time on the X-axis, then have a plot for your RPM and a plot for your dependent variable, which I think will be clearer than what you were trying to do.

i found a work around where i used two strict type def xy-graph and joined them together so that they look like one. But i get your point, i could go it that way also.
