What You Can Do With Plotgraphs.com
As long as you need a graph, we can help you to make it. One of the things you can do is the calculation of function derivatives through the intuitive graphical formula editor. You can also create 2D and 3D plots, and once the graph is done, it can be made available in different formats, such as JPG and PDF, making it easier to have it submitted easily. You no longer need to be in a struggle with your pen, paper, and calculator as everything can be easily accomplished with our revolutionary graphing calculator.
What Makes Us Different
While there are many options, you can see online when it comes to the best graphing calculator, we take pride in having an intuitive interface. Some are too complicated, which makes the entire task more difficult rather than extending a helping hand. At Plotgraphs.com, you will surely be able to create a graph in the most effortless way possible. Mathematical functions can be inputted without the need to be on a struggle with syntax. There are also
multiple functions per plot, which will make it possible for you to do more. Plotgraphs.com is a
free graphing calculator and plotting tool, which is another reason why you should choose us above others. You do not have to pay anything to enjoy premium service. Even if it is for free, we make sure that the graph will be accurate, and your experience is given priority. We also make it easy for you to export the graph in different printable formats. Aside from graphing, you can also calculate basic derivative functions. While this feature is still in its infancy and being tested, it is already very promising. As you can do more with our graphing calculator, you have more reasons to be thankful for discovering our website. In sum, if you have complex mathematical problems and if you need to plot a graph, do not forget to check our website. We will help to make math an easier subject for everyone through the numerous functions of our graphing calculator.
How to make an 2D plot - Instructions:
The Basics: It has never been that easy to
plot graphs online. Just press
edit and a prompt for entering the expression you want to plot will appear. Enter your function and press
plot. Here you go! The plot of your graph shows up immediately. To plot an
additional graph press
+ and then repeat the steps from above. The new graph will be added to your existing plot. If you want to remove a graph from your plot just press
- to delete it. Each new graph will be drawn in a new color. The colors are chosen automatically at the moment. In future we will allow you also to set a specific style for each of your particular plots.
Plot parametric functions:
- In the promt you can also choose to plot a parameric function `x(s)=s, y(s)=s^2` by clicking 'Parametric function' right at the top of the prompt. Important: The parameter has to be called 's'.
- Fine tuning: You have various possibilities to improve your result. In Axis properties you can set the X-range and the Y-range for your plot. Furthermore you can choose a logarithmic scale here and activate or deactivate grid lines. In General properties you can set the height and width of your plot in pixels. Furthermore you can set a custom title for your plot.
How to define general graph properties
- You can define the type of your graph (e.g. curve, points, bars etc.). Just click on "Graph Properties" and the available options will show up to you.
Handsome export feature for your Plots:
- You can export your plots using the export section at the top of the page. At the moment the formats PDF, SVG, PNG and JPG are available.
- The export feature is available for both 2d and 3d graphs
How to create 3-Dimensional Plots:
Yes, you can plot 3D functions here in a very comfortable and easy way. To get started choose '
3D Plot' in the main menu. A demo plot will appear at once. You now have two possibilities to enter the function you want to plot:
- 3D Graphs of implicit function definitions: If you want to plot an implicit function of the variables x, y and z you may enter it like follows: `z=x+y` or `3=x^2+y^2+z^2 ` or `z=1`. The position of the equal sign does not matter.
- 3D Plots of Explicit function: You can enter the function you want to plot also explicit as `f(x,y)=x^2+y^2`. Important: In that case the expression you have to enter in the formula editor is only `x^2+y^2`
- Note:There will be the same input for explicit and implicit functions. Implicit functions are detected automatically by the equal sign
- Axis range: It is possible to set the axis range of your 3D plot independently for the x-, y- and z-axis.
- Rotate the plot: You can change the angles under which your plot is seen using the buttons provided next to the input for the axis range.
- Export:To export your 3D plot you can proceed as described above.
My plot is empty and does not contain any graphs - what did I do wrong?
Don't panik and check the syntax of your input. Most probably you made some inconsitent input like `z=^+`. If predefined functions are multiplied an explicit dot is needed in between like `cos(x)*sin(x)` and not `cos(x)sin(x)`.
Function Derivatives
You can use this page to calculate derivatives of basic functions. The feature is still experimental but is steadily improved. To derive a function just enter it using our formula editor. By clicking the
f'(x) - Button next to the edit button the function will be derived and the derivative will also be plotted in the same coordinate frame as the original input. Please let us know in case you encounter any problems with this brandnew feature.
The terms of service
This service is available for free in the hope that it will be useful. It can be used by everybody to plot his graphs online. The plots can be exported on downloaded free of charge. Plots created by this service can be redistributed. However, there is no warrenty of any kind for the service provided by this website. Furthermore there is no warrenty for the correctness of the plots which are produced.
