Introduction: How LogarithmPlotter works
LogarithmPlotter is a software to create plots and graphs with a logarithmic scale, the most well known kind being Bode plots, which LogarithmPlotter helps create in asymptotic form. While logarithmic scales in the primary interest of LogarithmPlotter, LogarithmPlotter also supports non logarithmic scales, which may be required to use certain features.
To do that, LogarithmPlotter uses a system called Objects, which may seem familiar to you if you have used other plotting software like Geogebra.
An "object" is anything that can be reprensented on the graph. LogarithmPlotter allows you to create 9 types of objects:
| Icon | Type | Works well in logarithmic scale | Works well in non logarithmic scale | Allows pointer positioning | Comment |
|---|---|---|---|---|---|
 |
Points | ✓ | ✓ | ✓ | |
 |
Texts | ✓ | ✓ | ✓ | Used as additional labels if necessary |
 |
Functions | ✓ | ✓ | X | |
 |
Bode Magnitudes | ✓ | X | X | |
 |
Bode Phases | ✓ | X | ||
 |
X Cursors | ✓ | ✓ | ✓ | Cursors on the x-axis |
 |
Sequences | X | ✓ | X | There are several performance issues on the logarithmic scale related to having to calculate far to many values. You should use functions defined on N as a substitute if possible. |
 |
Distributions | ✓ | ✓ | X |
LogarithmPlotter will also create it's own objects automaticly when needed (for example, the sums of the bode gains and phases).
