In the case of the 3D graph, you can select one of the three available 3D graph plotting methods namely 3D circle , 3D Dot , and 3D Density.
Besides this, you can also add grid to the background of the graphs to get the classic graph view. This software also comes with a dedicated Analyze menu that allows you to convert plot data , set data point , and set plot range.
Plus, options to manually define plot lines , regression lines , Gaussian curve , and arbitrary function for graph analysis is also present in the Analyze menu. I See Graphs is yet another free scientific graph software for Windows.
This software is specially designed for teachers to teach graph making process to their students. Using it, you can easily create various different types of scientific graphs like Slider Graphs , Function Theory , Inequalities , Probability , 3D Graphs , Matrices , and more. For each type of graph, it provides a dedicated section.
By going to a specific section, you can input equations and coordinate values to plot the graph. Within each section, you get the corresponding graph, but you cannot export or save the graph. This software also comes with a fully fledged scientific calculator to help you solve equations. Apart from various tools and features, it also provides a really customizable interface that lets you select any combination of primary and secondary colors.
As a scientific calculator, it provides all important function , numerical keys , and calculation keys on its interface to perform mathematical and scientific calculations. Along with standard scientific calculator features, you also get various graph plotting features namely 3D surface , regression , fx graphics , and fx analyze. Overall, it is pretty easy to plot scientific graphs in this software, but this software does not allow you to save any of the graphs.
Dream Calc is a free scientific calculator software that also lets you plot scientific graphs. The main interface of this software is dominated by a virtual scientific calculator in which you can perform complex calculations. To access its Graphing feature, you need to press the F12 hotkey or access it from its Windows Menu. At any time, you can also change the unit of input coordinates to Degree , Radian , Grad , and Cycle to get output graph accordingly.
RJS Graph is the next free scientific graph software for Windows. This software is used to create professional 2D scientific graphs. So in this case you can turn the sequences of adjacent segments into paths:. From this figure you can select by double-clicking the path you are looking for, copy graphics selection and paste as new Graphics.
Now we have the points not in the coordinate system of the graph but in the coordinate system of the PDF file. We need to establish relationship between them. From the above plot you select ticks by hand holding Shift for multiple selection , then copy them and paste as new Graphics. Here is how you can extract coordinates of horizontal ticks:. From these differences you can see how precise is positioning of the ticks in the PDF file.
It gives an estimate of error introduced by converting original datapoints into vector graph included in the PDF file. If there are appreciable errors in ticks positioning you can reduce the error by fitting the coordinates of ticks to a linear model. This linear function now can be used to get original coordinates of points of the path that is in the coordinate system of the plot. Works in Linux and Windows.
