Hello,
I'm new to Simulink, and I'm stuck for a few days on the plot of a graph. I think I have to use the "1-D Lookup Table" block but I can't manage to use it correctly. I think I'm making a mistake in the "sample time"/"stop time" or in te use of a clock...
I want to plot a figure as if I was using the "plot" of matlab, I have data of electrical consumption per hour over one year so 8760 values. I have a table containing the 8760 consumption values and a table containing the hours (from 1 to 8760). But when I ask to plot, I only get a very rough graph... How can I do it?
Thank you for your answer.
An example of what I want to get: (but for the whole year)
What I get on Simulink :
My simulink screen:
And when I click on "edit table and breakpoints", I get this. And what I want is the plot on the right.
Thanks! :)

Mostly correct. Just need a few settings
  1. Press Ctrl+E to open the configuration parameters, set the Solver to be fixed step, discrete, set the step size to be 3600 seconds
  2. In the Scope, select menu View, Style, change options for "Line" and "Marker". You will get the smooth line plot, or the data points plot with the marker as "o".
