How do I plot a mathematical function in Mandriva?
The quick and easy solution is to use kmplot. If your installation of Mandriva is running under KDE, you should be able to access it from the main KDE menu, under
More applications -> Education -> Sciences -> kmplot (Figure 1).
The program is quite limited, but you'll get a fairly good looking plot in less than a minute, which can be quite handy from time to time.
In kmplot, simply click on the curve icon, enter the formula of the mathematical function you want to plot, hit apply, et voilà, you have your plot (Figure 2)!
Finally, you may want to play around with axis, colors, steps, and so on. All of those options can be found in the
You second option is to use the plotting tool Grace. Grace is more complex, but it is a full featured plotting software, so you'll be able to do way more that plot a basic curve.
I already wrote a tutorial on Grace, Scientific Plots with Mandriva Linux, so if you want to learn the basics, such as setting colors, axis, or many other options, have a look at it!
To plot a curve with
Grace, select the menu
Edit -> Data sets. In the datasets window, right-click on the clear area, and select
Create new -> By formula (Figure 3). In the formula window, enter your equation, and simply
Accept (Figure 4). For the plot in Figure 4 for instance, I enterred the following parameter:
- Parameter mesh starts at
0, ends at
x = $t
y = $t * sin($t)
Accept, and the
Autoscalebutton in the main window. Et voilà!
For more options, such as line colors or axis style, have a look at my old tutorial, Scientific Plots with Mandriva Linux, it's all there!
