There could be a few reasons for this. First, make sure that you have entered the correct data into the plot function. Check for any typos or missing brackets. Also, make sure that the data you are plotting is in the correct format for the plot function. Finally, check that the data is not too large or too small to be displayed on the plot.
To customize the appearance of your plot, you can use various options within the plot function. For example, you can change the color, style, and thickness of the plot line, add labels and titles, adjust the axes, and more. You can also use the "PlotStyle" option to specify a specific style for your plot.
You can use the "PlotRangePadding" option to adjust the spacing between data points on your plot. This allows you to add more white space around the plot, making it less crowded. You can also use the "PlotRange" option to specify the range of values to be displayed on the plot, which can help with spacing as well.
To add multiple plots to the same graph, you can use the "Show" function. This allows you to combine multiple plots into one by specifying them as arguments within the function. You can also use the "Epilog" option to add additional graphics or annotations to your plot.
You can use the "PlotRange" option to specify the desired range on the axes. This allows you to adjust the minimum and maximum values that are displayed on the x and y axes. You can also use the "AxesOrigin" option to specify the point where the axes intersect on the plot.
