You can use many options with your functions to specify exactly how the functions should work. Here is a list of all options available.
This changes the plot color to blue.
When you set an option you must use "->" This is because we want to separate
options from variables (to set a variable use "=")
If you want to use more than one options you separate them with "|" like
This is very important to remember because if you use "," it will not work and no warning message will be displayed either.
Whenever you plot a function, Eudox will try to scale the function right,
so you will get the best view of it. While this works very well in general,
it may sometimes give undesirable result, especially when ploting functions
with singularities. This plots tan(x) in the interval -Pi to Pi. Note
that tan(x) has singularities, in this case two singular points. The first
one at -Pi/2 and the second at Pi/2.
If Eudox does not scale the function right you can use the option PlotRange
to specify the visible area of the plot.
This plots the function sin(1/x)
The plot looks a bit strange between -0.25 and 0.25. This is because
the default value for how many plot points to use is to low. This plots
the same plot but with PlotPoints set to 5000.
This plot is more correct but it takes more time to calculate.
When you plot several functions and want to use individual options on the functions, you do like this. This plots two functions with some different plot options.
Here are two plots. The first is one with the option AxesStyle set to
Axes (default) and the second to Frame.
As you can see PlotStyle set to Frame looks much better on this specific plot.
This fills the area between the plot and the x-axis with a color.
This change the fill color to red.
Notice that only the graph is displayed (no fill color) and that the axes is now displayed as a frame. This is because only the function-values from the last plot are stored in "%" and AxesStyle is set to Frame by default with Show
This makes a density plot of function z=sin(x*y) in two different ways.
The first one with ColorFunction set to GrayLevel (standard value) and
the second one to Hue.
The second plot can be difficult to understand at the first look. It works like this: the color represents the z value, where red is max. After red comes pink, blue, light blue, green, yellow, orange and finally red again. To use red for both the maximum and minimum value is very good because you use all colors available to represent your values.
If you don't want to show the black grid (mesh) in the plot you can turn
in off by the Mesh option. This plots the same function but with Mesh
set to False.
As you can see it doesn't look that nice. We recommend that if you set
Mesh to False you should set PlotPoints to a high value.
This plots two functions, the fist one is x^2+y^2 and the second one
As you can see there is no difference! It seems like the multiplication
by 3 didn't hade any effect in the second plot. This is because Eudox
scales the plot so that you will always get a good view of the function.
However, if you would like to change the ratio between the z axis and
the x, y axes you can use the option ZRatio. ZRatio has default value
0.333 This plots the same functions as above but with ZRatio set to 1.
Note that even though you set ZRatio to 1 the two functions will look the same. So if you would like to show the difference you would have to use ZRatio set to 0.333 at the first and ZRatio set to 1 at the second.
