Plotting Definition and 560 Threads

Hi PF! I have a list of numbers, and I'm trying to plot each constant value on a 1-unit long interval. What I'm trying is this a = Table[i, {i, 2, 8}]; For[i = 1, i < 5, i++, Plot[a[[i]], {x, i - 1, i}] // Print] but that generates plots that are not on the same axes. Any help?

Hi PF! I type the following into Mathematica: domain = -10; ListPlot[{0.3}, PlotMarkers -> {{"\[LongDash]", Large}}, PlotRange -> {{0, 5.5}, {-10, 200}}] And notice we see the plot 0.3. But, now let domain = 0. Notice now we can't see 0.3. Does anyone know how to fix this?

how do you define x to be from minus pi to plus pi in matlab? i tried: x = -pi : piBut when i said plot (x,y) Matlab says: "Error using plot Data must be numeric, datetime, duration or an array convertible to double" (i already defined y interms of x, that function is ok) so i culd not...

i could use a bit of tutelage with Matlab. I have a rather simple equation I would like to plot. I want to create a rational series of primes divided by their corresponding W value from the equation I have. P are primes 2,3,5,7,11,13... I am still working on this. Thanks
