# faust2svgplot
## A tool to create SVG and HTML files of plotted values.
### Usage
```
faust2svgplot <options> <file.dsp>
./file -n (nb_samples)[default:4096]> -bs (buffer_size)[default:1] -r (sample_rate)[default:44100] -s (start_at_sample)[default:0] -sp (split)[default:0]
```
### Basic example
Here is a DSP code example:
```
import("stdfaust.lib");
process =
(
(
os.osc(100),
os.square(100)*0.15,
os.triangle(400)*0.15
)
);
```
<img src="example.png" class="mx-auto d-block" width="80%">
#### Notes
* in usage, insert in <file.dsp> your favourite Faust dsp file
### The probe metadata
You can use the `probe` metadata in bargraph in order to plot specific signals in the program. Here is a DSP code example:
```cpp
import("stdfaust.lib");
sendtoOut(n) = vbargraph("[probe:%n]label%n",0,1);
process =
(
(
((os.osc(100) : sendtoOut(1)),
(os.square(100)*0.15 : sendtoOut(2)),
(os.triangle(400)*0.15 : sendtoOut(3)))
:>_
)
);
```
<img src="probeexample.png" class="mx-auto d-block" width="80%">
### The split option
You can split your graph in multiples graph.svg for every probe and every channel.
* usage: `./file -sp 1`
<img src="splitexample.png" class="mx-auto d-block" width="80%">
#### Notes
* the probes are evaluated at every buffer size end.
If you want the maximum precision, you will need to have a buffer size of 1 sample (set to 1 by default).
